Choosing a commercial contractor is more than choosing someone who can build. It’s choosing a team that understands timelines, leases, budgets, brand standards, and the operational demands of running a business in one of the most competitive markets in the region.
Here’s why organizations across Northern Virginia rely on Treun:
Most commercial projects slow down because multiple contractors are coordinating independently, often with conflicting priorities. Treun operates differently.

Commercial construction pricing varies widely based on scope, building type, mechanical requirements, and finish level. However, most clients want a range before diving into planning. Typical starting points include:

Treun brings structured project management and multi-trade expertise to retail and restaurant construction, delivering spaces that align with both brand vision and operational function.
Retail Construction Services
Restaurant & Food Service Construction
Restaurants often involve more complex mechanical and health-code requirements. We handle:
Timeline Expectations

Restaurant projects: 12–28+ weeks
(Primarily influenced by kitchen requirements and inspections.)
Why Clients Choose Treun for Retail & Restaurants
Treun understands that in retail and restaurants, time is revenue, and precision cannot be compromised.
Tenant Improvement (TI) projects involve modifying leased spaces to meet a tenant’s functional, operational, and aesthetic needs. These projects often work within limited budgets, strict lease timelines, and defined landlord requirements. Treun’s ability to manage TI work efficiently while keeping both tenant and landlord aligned makes us a strong partner for property management groups, commercial tenants, and multi-tenant building owners.
Common Types of TI Projects

We understand the dynamics of:
Treun helps tenants maximize their TI allowance while supporting landlords in maintaining the building’s long-term functionality.
Why Clients Choose Treun for Tenant Improvements
TI projects require clarity and efficiency — and Treun is structured to deliver both.
Commercial buildings in Northern Virginia vary significantly in age and infrastructure. Many properties require strategic upgrades to meet modern codes, improve performance, enhance tenant satisfaction, or extend the life of critical building systems. Treun supports owners and property managers with facility upgrades and capital improvements that align with long-term planning and operational goals.

Capital Improvement Support
We assist building owners and property managers with:
What Makes Treun Effective in Facility Upgrades
Facility upgrades are not routine repairs — they are strategic investments that shape building performance, tenant satisfaction, and long-term asset value. Treun delivers those improvements with the planning and precision they require.
Commercial construction costs vary significantly based on building type, existing conditions, scope, and required mechanical systems. Business owners, building managers, and tenants often
need a realistic range before entering preconstruction, so this section provides the foundational guidance they’re searching for.
These ranges reflect current Northern Virginia market norms:
Office Build-Outs
Major cost drivers for office spaces include glazing, specialty ceilings, lighting packages, and IT rooms requiring enhanced electrical systems.
Retail Construction
Retail costs increase with custom millwork, display systems, and specialty lighting.
Restaurant Construction
Restaurants consistently have the highest cost range because they require:
Typical Range:
$200–$600+ per sq. ft.
Tenant Improvements (TI)
TI costs vary widely based on:
General Range:
$40–$300+ per sq. ft.
Facility Upgrades & Capital Improvements
These projects don’t always have a per-square-foot price because they are system-driven. Common cost drivers include:
Costs depend heavily on the building’s age, system condition, and required phasing.
Mechanical, Electrical, and Plumbing (MEP) Complexity
MEP often represents 40–60% of the cost in restaurants and heavy-use spaces.
Existing Building Conditions
Older buildings may require:
Material and Finish Level
Luxury finishes, custom millwork, and specialty lighting significantly influence cost.
Kitchen or Specialty Equipment
Restaurants and medical spaces require specialized coordination.
Phasing and After-Hours Work
Occupied buildings increase labor hours.
Permitting and Inspections
More complex spaces undergo stricter review processes.
Treun helps clients identify these cost drivers early, allowing for better planning and more informed decision-making.
This is where the project is truly shaped. Our preconstruction work includes:
Preconstruction reduces surprises and improves cost accuracy.
