Washington DC Architecture & Engineering
TCG provides in-house architectural design, structural engineering, and MEP engineering across the DC metro, integrated with construction under one design-build contract for a single point of accountability.
DC Metro Design-Build Cost Estimator
Describe your project (DC, Northern Virginia, or Maryland) and get a preliminary construction cost estimate. TCG can carry it from design through delivery under one contract.

Your DC Metro Construction Cost Estimate
Design and Construction Under One Roof
Terrapin Construction Group provides integrated architecture and engineering across the DC metro from One Franklin Square, 1301 K St NW, Washington, DC 20005. Most projects separate the designer from the builder, which creates coordination gaps, change orders, and finger-pointing. TCG's design-build model puts architectural design, structural engineering, and MEP engineering on the same team as construction and preconstruction, so the design is buildable, budgeted, and permit-ready from the start. Architects are licensed in Virginia through DPOR and across the DMV.
This matters in a tri-jurisdictional market. Designing for DC, Virginia, and Maryland means three code environments, three permitting paths, and, in the District, historic and height constraints. A team that designs and builds understands how each choice affects cost and schedule. Learn how design-build compares in our design-build vs CM-at-risk vs design-bid-build guide.
Architecture, Structural, and MEP In-House
TCG delivers full architectural design, structural engineering for steel, concrete, and PEMB, and MEP engineering for mechanical, electrical, plumbing, and specialty systems. Integrating these disciplines with construction reduces rework and accelerates permitting. For complex building types (labs, data centers, cold storage, cannabis), in-house engineering is a real advantage because the systems are the project. Understand fee structures in our guides on architectural services cost and value and A&E fees and soft costs. See why design-build is winning.
Statewide Virginia reach. TCG designs and builds across Virginia and coordinates with our Richmond and Virginia Beach teams for statewide A&E and construction.
What Design and Engineering Cost in the DC Metro
Architectural and engineering fees generally run a percentage of construction cost that varies by building complexity, with simple shells at the low end and labs, data centers, and healthcare at the top. Soft costs (design, permitting, testing, and project management) typically add a meaningful percentage on top of hard construction cost. The design-build advantage is not just lower fees; it is fewer change orders, faster permitting, and single-point accountability.

Washington DC Frequently Asked Questions
Common questions about architecture and engineering for DC metro projects.
Yes. TCG delivers in-house architectural design, structural engineering, and MEP engineering, integrated with construction under one design-build contract.
Design-build puts design and construction on one team, which means single-point accountability, fewer change orders, and 15 to 30 percent faster delivery. In a tri-jurisdictional, prevailing-wage market, schedule compression translates directly to savings. See our delivery method comparison.
Fees generally run a percentage of construction cost that scales with complexity, and soft costs add a meaningful percentage on top. See our A&E fees and soft costs guide.
No. TCG can start from a concept and provide full design, or bid from existing plans as a general contractor. Try the estimator above or book a call.
Yes. In-house engineering is a real advantage on labs, data centers, cold storage, and cannabis, where the mechanical and structural systems are the project.
Yes. TCG designs and builds statewide and coordinates with our Richmond and Virginia Beach teams. Architects are licensed through Virginia DPOR.
