deMartin Dunham Builders is a Cape Cod based design-build firm
focusing on high-end residential properties.

As a boutique firm, we provide highly personalized design and building services to discriminating homeowners. Our staff works one-on-one with our clients to craft a design that fits your lifestyle and personal vision – decidedly not a one-size fits all approach. During construction, we continue this personalized service to ensure the project comes together exactly as you envision it.

Our reputation is built on years of custom home design/build experience, meaningful client relationships, and solid supplier partnerships to provide the highest standard of quality and craftsmanship. We prioritize integrity and trust in our partnerships with clients and vendors, believing that relationships are the glue that holds everything together.

With decades on Cape Cod, we understand that this area is a unique ecosystem and are intimately familiar with the laws and regulations surrounding renovations and new construction. The importance of this cannot be overstated since dealing with complex federal, state, and local regulations is critical to completing projects on time and on budget.
