Commercial Design-Build Contractor in Connecticut
Design and construction managed under one contract, one team, and one point of contact from concept through completion.

Design and Construction Under One Roof
Design-build puts design and construction under a single contract. You get one team responsible for both, which means fewer handoffs, faster project timelines, and a single point of contact from the first sketch through the final walkthrough.
Advanced Construction operates a dedicated Design/Build Division that handles commercial design-build projects across southeastern Connecticut. Our design-build services cover concept development, space planning, material selection, engineering coordination, and full construction execution. We work with business owners, developers, and property managers on commercial design-build projects in Mystic, New London, Groton, Stonington, and the surrounding region.
Concept and Space Planning
We work with you to define the project scope, layout, functional requirements, and design direction before construction begins. Our design-build approach includes floor plans, elevations, material boards, and engineering coordination.
In-House Design and Engineering
Our Design/Build Division handles architectural plans, structural coordination, and material specifications. We coordinate with licensed engineers for structural, mechanical, and civil requirements on commercial design-build projects.
Integrated Construction
The same team that designed your project builds it. There are no gaps between what was drawn and what gets built, because the designers and builders work together throughout the entire project.
Where Commercial Design-Build Fits
Design-build works best when speed matters, when the scope is still being defined, or when coordinating separate design and construction teams would slow the project down.
Restaurant and Retail Design-Build
Concept-to-keys for new restaurants, storefronts, and hospitality venues where the design evolves alongside construction. Our design-build approach lets restaurant and retail clients make decisions in real time without derailing the schedule.
Commercial Tenant Improvement Design-Build
Commercial spaces built out for new tenants where the layout, finishes, and mechanical systems all need to come together on a tight timeline. Design-build tenant improvements move faster because design and construction overlap.
Renovation Design-Build
Existing commercial spaces being reimagined with new layouts, finishes, and functionality. Design-build renovation projects benefit from having the construction team involved during the design phase, identifying structural and mechanical constraints before they become change orders.
