Let’s talk about your project.

Why Homeowners Choose Treun

The Part Where Contractors Usually Disappear? We Don’t Do That Here.

Most residential projects fall apart long before the drywall goes up.

Miscommunication, unclear scopes, late crews, disappearing subcontractors — homeowners end up managing chaos they never signed up for.

Treun Construction Group was built to eliminate all of that.

We’re a woman-owned, detail-driven construction company with every trade under one roof, meaning you never have to chase down separate contractors or figure out who’s responsible for what. We keep your project moving, your decisions simple, and your sanity completely intact.

What Makes Treun Different?

All Trades Under One Roof

Electricians, plumbers, carpenters, masons, roofers — coordinated by one team that actually talks to each other.

Licensed in Every Trade That Touches Your Home

No patchwork subcontracting. No guessing. No shortcuts.

Detail-Driven Leadership (Yes, It Shows)

Schedules, scopes, updates, selections — everything runs tighter and cleaner when someone is paying attention.

Transparent Scopes + Predictable Timelines

You know what’s happening, when it’s happening, and why. No vague allowances or contractor magic tricks.

A Single Point of Contact

One project manager. One communication line. No confusion. No “We’ll ask the other guy.”

Craftsmanship That Lasts

We don’t do band-aid work. Everything is built to withstand years of use, not just inspection day.

Respect for Your Home

Clean job sites. Professional crews. Clear expectations. You’d be surprised how rare this is — but it shouldn’t be.

A Better Residential Experience Is Possible. We Build It Every Day.

Whether you’re remodeling a kitchen, expanding your home, or starting fresh with a custom build, Treun provides a level of organization and accountability that homeowners in Northern Virginia rarely experience and always appreciate.

Custom home construction

Custom Home Construction — Built Around Your Life, Not a Template

There are two kinds of homes in Northern Virginia: the ones people settle for, and the ones people intentionally create. If you’re here, you’re probably leaning toward the second type — and that’s exactly where Treun Construction Group excels.

Building a custom home is not just about walls, windows, and square footage. It’s about designing a space that supports how you live today, and how you’ll live ten years from now. It’s about craftsmanship you can feel, layouts that make sense, and a building process that respects your time, your budget, and your sanity.

Most importantly, it’s about having a construction team that doesn’t disappear the moment the plans get complicated.

Treun brings every trade under one roof from excavation to electrical to finish carpentry so you’re not stuck coordinating separate contractors or guessing who’s responsible for what. The result? A custom home build that actually feels custom, not chaotic.

What “Custom Home” Really Means at Treun

Below is the full pillar-page write-up for each service area.

Every project starts with learning how you actually want to live.

Do you entertain often? Need a mudroom that can survive kids, pets, and Virginia weather? Dreaming of a chef’s kitchen or a spa-level bathroom?

We focus on the functional and personal details that transform a house into your home.

Architectural Coordination Without the Headaches

Some clients come with an architect already on board; others need help choosing one.

Either way, we act as your advocate — ensuring plans are buildable, structurally sound, budget- aligned, and compliant with county requirements.

Architects love when we’re involved early. Homeowners love it even more.

Engineering and Permits (Handled, Not Handed Off)

The fastest way to derail a custom home is to underestimate the complexity of permitting in Northern Virginia.

We handle:

Structural engineering
Soil work & grading
Site plans
County approvals
Utility coordination
Inspections

You won’t have to learn what a footing detail is or why Fairfax County cares about stormwater flow.

(Unless you want to. We won’t stop you.)

All Trades Under One Roof: The Number-One Advantage in Custom Home Construction

The average home build requires dozens of specialists — plumbers, electricians, masons, framers, HVAC techs, roofers, tile installers, painters, and more.

Most companies subcontract nearly everything. That means:

Miscommunication
Delays
Finger-pointing
Inconsistent craftsmanship
Homeowners being the “middleman” between trades Treun eliminates that entire dynamic.

Here’s what happens instead:

One coordinated construction team
One project manager

One consistent schedule
One standard of quality
One contractor accountable for the entire home

It’s the difference between building a custom home… and trying to assemble one from disconnected parts.

Quality That Lasts Decades — Not Just Until the Warranty Expires

A custom home is a long-term investment, so durability matters just as much as design. Our builds emphasize:

Structural integrity
Moisture control
High-efficiency systems
Proper ventilation
Premium materials (not builder-grade shortcuts)
Craftsmanship that stands up to actual daily use

This is where “woman-owned detail-driven leadership” isn’t a slogan — it’s a standard.

If something feels off, looks sloppy, or won’t hold up long-term, it doesn’t get installed. Simple as that.

A Transparent Process — No Surprises, No Contractor Mysteries

Custom home construction often feels unpredictable. Homeowners expect delays, vague explanations, and shifting budgets because that’s what the industry taught them to expect.

Treun does it differently.

We provide:

Transparent estimates with clear allowances

Upfront discussions about feasibility and cost impacts
A predictable build schedule
Weekly updates
Digital progress tracking
Proactive communication about decisions You’re never left wondering:

“What’s happening this week?” “Who’s on site today?”

“Why is this taking longer?” “What am I waiting on?”

You’ll always know.

Making the Big Decisions Easier

A custom home comes with hundreds of decisions — layout, materials, finishes, fixtures, lighting, flooring, hardware, tile, cabinetry, appliance specs… the list goes on.

We simplify this with:

Guided design support
Showroom partnerships
Coordinated material scheduling
Early procurement to avoid delays
Recommendations that balance aesthetics, durability, and cost You don’t need to be an expert.

You just need a contractor who can help you make confident decisions.

How Treun Protects Your Budget (and Your Stress Level)

Custom homes don’t go over budget because homeowners overspend — they go over budget because contractors under-scope, under-plan, and “figure things out later.”

We prevent that with:

Extremely detailed scope development
Clear material allowances
Builder-ready construction documents
Early-stage engineering review
Realistic scheduling
No “surprise” change orders for items we should have planned for You get the truth upfront, not halfway through framing.

Who This Service Is Perfect For

Treun’s Custom Home Construction service is ideal for homeowners who:

Want a fully personalized home
Value organization, transparency, and strong project management
Prefer one accountable contractor, not a rotating cast of crews
Care about craftsmanship and long-term durability
Expect professionalism from every person on site

If you want a team that treats your home as a legacy project — and treats the process with the seriousness it deserves — we’re the right fit.

Home Renovations & Additions

When Your Home Needs to Grow, Improve, or Finally Make Sense, We Build the Space That Fits Your Life

Homes evolve. Families get bigger, layouts stop working, storage disappears, and the kitchen you inherited from the previous owner starts reminding you why they moved.

A smart renovation or well-planned addition doesn’t just upgrade a house — it fixes the daily frustrations that keep it from feeling like home.

Treun Construction Group specializes in transforming Northern Virginia homes with renovations and expansions that improve flow, add functionality, and elevate the way you live. Whether you’re opening up the main floor, adding a second story, extending the back of the home, or modernizing outdated rooms, we bring the structure, clarity, and craftsmanship your project deserves.

And because every trade is under one roof, your renovation doesn’t dissolve into contractor chaos halfway through. It moves forward — cleanly, strategically, and with a team that actually communicates.

When an Addition Makes More Sense Than Moving

Northern Virginia homes often have the perfect location… and imperfect square footage. Instead of starting over in a new neighborhood, many homeowners choose to expand where they already live.

We build:

Second-Story Additions

Add bedrooms, bathrooms, or a full upper-level suite without sacrificing your yard.

Rear Extensions

Expand kitchens, living rooms, or dining areas to create the open, modern spaces today’s families want.

Garage Conversions

Turn underused square footage into guest suites, gyms, offices, or full living spaces.

Sunrooms & Four-Season Rooms

Bring in more natural light and usable year-round space without a full-scale expansion.

Treun’s structural and architectural coordination ensures your addition looks and feels seamless not like something that was bolted on as an afterthought.

Renovations That Improve Daily Life

A great renovation doesn’t just change how your home looks it changes how effortlessly everything works.

We deliver thoughtful, technically sound upgrades to:

Main Living Areas

Open-concept designs, load-bearing wall modifications, circulation improvements, custom carpentry, and more.

Basements

From simple finishing to full second-living spaces with bathrooms, bars, egress windows, and media rooms.

Bedrooms & Suites

Walk-in closets, ensuite bathrooms, layout redesigns, and upgrades that make your private spaces feel elevated.

Whole-Home Renovations

A full reset tailored to older NOVA homes that need modernization from top to bottom — mechanicals, electrical, layout, and finishes.

We’re especially familiar with the quirks of Northern Virginia construction — 1940s bungalows, 1960s colonials, 1980s builder-grade layouts — and we know exactly how to bring them up to today’s standards without losing their character.

Clear Scopes, Predictable Schedules, No Drama

Renovations are notorious for surprises… mostly because contractors don’t plan ahead or coordinate trades.

We do both — obsessively.

Treun’s renovation and addition process includes:

A detailed scope of work before construction begins
Structural evaluation to prevent mid-project surprises
Permit management and county compliance
Early material selection to avoid delays
Full-time project oversight
A single point of contact
Weekly updates you don’t have to chase

You’re never left wondering why nothing happened today, who’s showing up tomorrow, or where things stand.

Structural Challenges? Old Layouts? Awkward Rooms? We Thrive on This Stuff.

Many renovation contractors only want the “easy” jobs. We’re not that company.

We routinely handle:

Load-bearing wall removals
Foundation work for additions
HVAC re-routing
Electrical and plumbing upgrades
Complex framing adjustments
Waterproofing and drainage corrections
Code and safety updates in older homes

The harder the problem, the more our all-trades-under-one-roof model shines.

Designed for Today’s Lifestyle — Built for Tomorrow’s Durability

Your renovation or addition isn’t something that should just look good on move-in day. It needs to stand up to everyday living.

Treun focuses on:

High-quality craftsmanship
Moisture management
Proper insulation and ventilation
Long-lasting materials
Workmanship that reduces future maintenance

When everything is built correctly the first time, it saves you time, money, and headaches later.

Who This Service Is Perfect For

You’ll love working with Treun if you’re a homeowner who:

Needs more space but doesn’t want to move
Wants a layout that finally works for daily life
Values organization, clear communication, and true project management
Wants one accountable contractor not a revolving door of subs
Expects craftsmanship that lasts

If your home is ready for a smarter layout, more room, or a complete refresh, we’re ready to build it.

Kitchen & Bathroom Remodeling

The Two Rooms Everyone Uses — and the Two Rooms Most Construction Projects Mess Up

Kitchens and bathrooms are the heartbeat of a home.

They’re where mornings begin, meals happen, guests gather, and long days finally wind down. When they’re outdated or poorly designed, you feel it every single day.

When they’re remodeled well, the entire home feels elevated.

Treun Construction Group specializes in remodeling kitchens and bathrooms with craftsmanship, clarity, and all trades under one roof — which means your plumbing, electrical, tile, cabinetry, and finishes all move forward in sync, not in conflict.

No disappearing tile guy.

No plumber blaming the electrician.

No “your vanity is delayed… we think.”

Just a smooth, well-coordinated renovation led by a team that knows how to manage every detail.

A Better Kitchen Starts With Better Planning

Most kitchen remodels fail long before demo day. Wrong measurements, missing materials, unclear scopes, and a “figure it out later” approach cause cost overruns and chaos.

Treun solves all of that with thoughtful design coordination and tight project management.

We Remodel Kitchens With:

Smarter Layouts

Open-concept conversions, workspace optimization, appliance relocations, and traffic flow improvements.

Custom Cabinetry Options

From full-overlay modern cabinets to timeless inset designs — built for durability and storage efficiency.

Electrical & Lighting Upgrades

Recessed lighting, under-cabinet lighting, dedicated appliance circuits, and code-compliant panel upgrades.

Plumbing Improvements

Sink relocations, new supply lines, modern fixtures, filtration systems — done by licensed professionals.

High-Quality Countertops & Backsplashes

Quartz, natural stone, porcelain slabs, custom tile patterns — installed with precision.

Flooring That Survives Real Life

Hardwood, luxury vinyl, tile — chosen for beauty and performance.

Whether you want a bright modern kitchen, a warm traditional space, or a chef-level layout for hosting and cooking, we build kitchens that work as beautifully as they look.

Bathrooms That Feel Like a Retreat and Function Like a Workhorse

Bathrooms aren’t just utility rooms anymore.

When designed well, they add luxury, comfort, and value to your home.

When designed poorly, they lead to leaks, mold, layout frustrations, and costly repairs.

Treun’s bathroom remodels combine aesthetics with technical expertise — especially important in Northern Virginia’s older homes.

We Remodel Bathrooms With:

Luxury Showers & Wet Rooms

Zero-threshold entries, frameless glass, linear drains, handheld + rain shower systems, steam options, and waterproofing that actually protects your home.

Updated Plumbing & Ventilation

Hot-water efficiency, moisture control, drain upgrades, and exhaust systems that prevent mold and humidity damage.

Elegant Tilework

Porcelain, ceramic, natural stone, mosaic patterns, niche shelving — installed by craftsmen, not hobbyists.

Custom Vanities & Storage

Built-in cabinetry, floating vanities, linen storage, integrated lighting, and durable finishes.

Heated Floors & Comfort Features

Radiant heat, smart fans, LED mirrors, dimmable lighting — little touches that make a big difference.

Efficient Redesigns

Reworking awkward layouts, enlarging showers, improving circulation, and making every inch feel intentional.

The result is a bathroom that feels like a spa but functions perfectly for everyday life.

Coordinated Trades = Renovations That Don’t Derail

Kitchens and bathrooms rely on multiple licensed trades working in tight quarters:

Plumbers
Electricians
Carpenters
Tile installers
Countertop fabricators
HVAC technicians
Painters
Flooring specialists

When these roles are scattered across multiple subcontractors — each on their own schedule — things fall apart fast.

Treun keeps everything under one roof and one project manager, so you get:

A predictable timeline
Fewer delays
No miscommunication
No “He said / they said” contractor drama
A consistent standard of quality
A crew that respects your home

You’ll see progress every week — not excuses.

Design Support Without Overwhelm

Choosing tile, cabinets, fixtures, counters, lighting, paint colors, and hardware can feel like a full-time job.

We help simplify the process with:

Material selection guidance
Showroom partnerships
Lead-time verification
Early procurement to avoid delays
Clear communication about how each decision affects cost and schedule

You don’t need to know the difference between a bullnose edge and a Schluter profile — we walk you through everything.

Modern Function, Lasting Craftsmanship

Every remodel is built for long-term durability, not just first-day aesthetics. We prioritize:

Proper waterproofing (a surprisingly rare skill)
Code-compliant electrical work
Long-lasting plumbing connections
Correct substrate installation
Moisture control
High-performance materials
Tight finish work

Because nothing is “custom” if it falls apart in a year.

Who This Service Is Perfect For

Our kitchen and bathroom remodeling services are an ideal fit if you:

Want a modern, functional, beautiful space
Need a contractor who actually manages the trades
Prefer clarity and communication over unpredictability
Value craftsmanship and long-term durability
Want a collaborative design + build experience
Don’t want to chase contractors or figure things out alone

If these rooms are ready for an upgrade (or a complete transformation), we’re ready to build it right.

Roofing & Exterior Improvements

Because the Outside of Your Home Deserves the Same Attention as the Inside

A beautiful home shouldn’t stop at the drywall.

Your exterior is the first thing people see and the first line of defense against Northern Virginia weather — rain, heat, humidity, wind, and whatever else the seasons decide to do. When your roofing, siding, decks, windows, or exterior trim start showing their age, the whole home feels it.

Treun Construction Group upgrades and protects your home’s exterior with durable materials, licensed trades, and craftsmanship that’s built to last. Whether you’re refreshing curb appeal, addressing storm damage, replacing an aging roof, or expanding your outdoor living space, we handle every detail with the precision and coordination your home deserves.

Professional Roofing That Protects Your Home for Decades

Roofing is one of the most important and most overlooked parts of a home until there’s a leak, stain, draft, or water where it shouldn’t be.

A roof replacement or repair isn’t just a maintenance task; it’s a major structural safeguard. Treun installs and services:

Asphalt Shingle Roofing

Durable, cost-effective, and available in premium architectural styles that elevate curb appeal.

Metal Roofing

Long-lasting, energy-efficient, and ideal for homeowners seeking superior protection and a modern look.

Flat Roofing Systems

Perfect for additions, garages, porches, and contemporary designs that require proper drainage and waterproofing.

Roof Repairs & Diagnostics

Targeted repairs, flashing corrections, leak detection, and ventilation improvements to address problems before they escalate.

Every roof we install is built with proper underlayment, ventilation, and moisture control — the technical details that most homeowners never see, but always benefit from.

Siding, Trim, and Exterior Restoration

Exterior materials fade, crack, warp, and weather over time — especially in climates with hot summers and cold winters.

We restore and enhance your home’s exterior envelope with:

Siding Installation & Replacement

Fiber cement, vinyl, engineered wood, composite — selected for durability and style.

Exterior Trim & Fascia Work

Custom carpentry, rot repair, waterproofing, and crisp finishing details that make the home look sharp and intentional.

Window & Door Replacement

Energy-efficient upgrades that eliminate drafts, improve insulation, and increase comfort year- round.

Ridge Vents, Gutter Work & Ventilation Improvements

Small upgrades that dramatically improve performance and prevent future damage.

These improvements don’t just change how your home looks they improve how it withstands the elements.

Decks, Porches & Outdoor Living Spaces

Outdoor spaces should feel like an extension of your home, not an afterthought. Treun builds and renovates:

Custom Decks

Composite or natural lumber, high-quality framing, modern railings, and layouts that maximize usable space.

Screened Porches & Covered Structures

Protection from bugs, sun, rain, and humidity — perfect for Northern Virginia’s changing seasons.

Front Porches & Entry Enhancements

Architectural elements that increase charm, functionality, and curb appeal.

Exterior Stair Systems

Safe, durable, properly framed stairways with code-compliant rises and runs. Built right, these spaces become some of the most enjoyable areas of your home.

Storm Damage, Repairs & Exterior Assessments

Wind storms, heavy rain, fallen branches, and hail can all leave your home vulnerable. We provide:

Roofing assessments
Siding repairs
Structural inspections
Leak and moisture diagnostics
Fascia and soffit replacement
Insurance documentation assistance

Fast, reliable repairs prevent small issues from turning into expensive problems.

Why Homeowners Trust Treun With Exterior Work

Exterior construction requires coordination of multiple licensed trades roofers, carpenters, siding installers, window specialists, and waterproofing experts. Most contractors subcontract each trade separately, leaving the homeowner stuck managing communication, scheduling, and quality control.

Treun handles everything under one roof, offering:

One accountable contractor
One project manager
A consistent standard of craftsmanship
Detailed material selection guidance
Predictable timelines
Clean job sites
Results that actually last

We treat the outside of your home with the same care and attention as the inside.

Who This Service Is Perfect For

You’ll benefit most from our exterior services if you:

Need a new roof or suspect yours is failing
Want to upgrade curb appeal with modern siding or trim
Are planning to build or renovate a deck or porch
Want better energy efficiency through upgraded windows & doors
Need long-lasting repairs after storm damage
Prefer one coordinated contractor instead of juggling multiple crews

If the outside of your home is ready for improvement — whether subtle or major — we’re ready to build something better.

Our Process

A Construction Process Designed to Remove Surprises, Stress, and “Why Didn’t Anyone Tell Me This?” Moments

Most construction frustrations come from one thing: a lack of structure. Not here.

Treun’s residential process is built to keep projects moving smoothly, decisions simple, and communication crystal clear.

No guesswork. No disappearing crews. No mystery timelines. Here’s how we turn your vision into a well-built reality:

1. Discovery & Consultation

Every project begins with a conversation — not a sales pitch.

We learn what you want to change, how you live, what’s frustrating you, and what success looks like for your home.

Then we walk the space (physically or virtually), identify constraints, and confirm feasibility. This step ensures we’re designing solutions around real needs, not assumptions.

2. Detailed Scope & Transparent Estimate

This is where our all-trades-under-one-roof advantage becomes obvious. We don’t throw out ballpark numbers or vague allowances.

We build a detailed scope of work, review options, and outline structural needs, materials, and realistic expectations.

You receive:

A clear estimate
Defined scopes
Transparent allowances
No-surprise cost visibility

This is how we prevent the “contractor changed the price halfway through” story you’ve probably heard a dozen times.

3. Design, Planning & Material Selection

Whether you’re choosing tile, cabinetry, windows, fixtures, or flooring, we guide you through the decisions that impact both function and budget.

We assist with:

Material recommendations
Lead-time verification
Structural and layout planning
Cabinet and finish selections
Showroom coordination

Everything is chosen early and ordered early — eliminating the delays that slow most renovations and new builds.

4. Construction & On-Site Management

Once construction begins, your project manager oversees every trade, every sequence, and every detail.

This includes:

Daily coordination of all crews
Ensuring trades don’t overlap or conflict
Quality control and inspections
Keeping the job site clean and safe
Weekly updates so you’re always informed

Because we control the trades, the schedule stays on track.

Because we communicate clearly, you never wonder what’s happening or who’s on site.

5. Quality Assurance, Punch List & Final Walkthrough

When work is complete, we don’t rush you through a quick “looks good, right?” moment. We conduct:

A meticulous quality check
A formal punch list
A full walkthrough with your project manager
A final review of all completed work
Guidance on maintenance, care, and warranties

Only when everything aligns with our standards and yours do we consider the project complete.

A Better Experience From Start to Finish

Our process isn’t built around speed or shortcuts.

It’s built around accuracy, clarity, craftsmanship, and communication — the things that make residential construction not only successful, but surprisingly enjoyable.

When every trade, every decision, and every detail is managed under one roof, the entire process just works better.

And so does your home.

Frequently Asked Questions

How much does a kitchen remodel cost in Northern Virginia?

Kitchen remodels vary depending on layout changes, cabinetry, electrical work, and finish level. We provide a detailed, transparent estimate based on your specific design goals so you know exactly what to expect before construction begins.

How long does a kitchen remodel take?

Most kitchen renovations take 2–6 weeks once construction begins, depending on complexity, material lead times, and structural changes.

How much does a bathroom remodel cost?

Bathroom remodel costs vary widely depending on size, plumbing changes, tile selection, and custom features such as walk-in showers or heated flooring.

We prepare a clear scope and estimate so you can make informed decisions.

How long does a bathroom remodel take?

A typical bathroom renovation takes 2–3 weeks, depending on the level of complexity and the materials you choose.

How long does a home addition take to build?

Most additions require 2–6 months, after the permitting. This includes the entire process from foundation to roofing and everything in between, such as, framing, mechanicals, inspections, and finishing work.

Do I need permits for a home renovation or addition in Virginia?

Yes most structural, electrical, plumbing, and mechanical work requires permits. Treun can handles all permitting, county submissions, and inspections on your behalf.

Can I live in my home during a renovation?

It depends on the scope of work.

Smaller projects can often be sectioned off, while whole-home renovations or second-story additions may require temporary relocation for comfort or safety.

Can my home support a second-story addition?

Many homes can support a second story, but some require engineering reinforcement. We evaluate your structure, foundation, and local zoning requirements before confirming feasibility.

Do I need an architect for a home addition?

We can work seamlessly with your architect or provide design-build support.

Both approaches work what matters is early coordination to ensure buildability and accurate budgeting.

How much does a roof replacement cost?

Pricing depends on roofing material (asphalt, metal, etc.), roof pitch, size, and existing conditions.

We provide a thorough assessment and clear estimate before any work begins.

How long does a roof replacement take?

Most asphalt shingle roofs can be replaced in 1–2 days, weather permitting.

Is Treun a “custom home builder near me”?

If you live in Northern Virginia, yes. We can build custom homes throughout McLean, Arlington, Alexandria, Vienna, Great Falls, Tysons, Falls Church, Fairfax, and surrounding communities.

How much does it cost to build a custom home per square foot?

Square-foot pricing is often misleading because it doesn’t account for design complexity, engineering, site conditions, and finish level.

We provide accurate, project-specific estimates during the planning phase.

How long does it take to build a custom home?

Custom homes typically take 8–14 months, depending on design, permitting timelines, and material selections.

Do you build ADUs (Accessory Dwelling Units)?

Yes.

We design and build ADUs such as guest houses, in-law suites, rental units, and detached or attached living spaces complete with full permitting and structural planning.

How much does it cost to build an ADU in Northern Virginia?

ADU costs vary by size, utility connections, zoning requirements, and finishes.

We perform a feasibility review and provide a detailed estimate tailored to your property.

What’s the difference between working with a design-build firm and hiring an architect separately?

Design-build streamlines everything under one team, reducing miscommunication and keeping the project on schedule.

Working with an independent architect also works — as long as your contractor and architect coordinate early and often.

Each has it’s own advantages. The design-build sometime could save you from paying separately for architectural fees, and will make the full responsibility of the design and structure on the firm providing this service.

At the same time, working with an architect in advance will help you achieve a design or layout that works with your need first and foremost, rather than work with the builder’s needs. Also, having an architectural drawings upfront will allow you to shop around for builders and compare apples to apples.

Can Treun work with plans I already have?

Yes.

We frequently build from architect-prepared plans and coordinate closely with your design team to ensure accuracy, feasibility, and cost alignment.

Does remodeling increase home value in Northern Virginia?

Yes.

Kitchens, bathrooms, additions, and exterior improvements often increase both comfort and resale appeal.

We guide you toward upgrades that make sense for your home and neighborhood.

Is it cheaper to renovate or move?

In many Northern Virginia neighborhoods, renovating or adding space is more cost-effective than buying a larger home — especially if you love your current location.

Who handles materials and selections us or the builder?

We guide you through the entire selection process, verify lead times, coordinate with showrooms, and ensure everything aligns with your schedule and budget.

What is the first step to start a remodeling or addition project?

Simply schedule a consultation.

We walk the space, understand your goals, and outline a clear plan no pressure, no obligation.
