D|A is a full service architectural firm founded in 1995. We maintain a diverse practice assisting clients in both the private and public sectors. Our projects vary from one-of-a-kind custom residences to large-scale, multi-use developments.
Past projects include new construction and building additions, as well as comprehensive renovations, modernization, rehabilitation, and historic preservation work. Our continued involvement with local and state agencies has kept us current with the comprehensive regulatory requirements and building codes governing today's construction industry.
We believe in taking a whole building approach, designing your building as a single integrated system—a key strategy in sustainable design. The collaboration of architect and owner with engineers and contractors results in a building that ages well and is energy efficient, healthy, safe, affordable, and comfortable.
While maintaining a primary practice in the seacoast of New Hampshire, DeStefano Architects is comprised of uniquely qualified individuals who are registered to practice architecture across New England.
D|A is dedicated to creating environments that function with efficiency, enhance productivity, and improve quality of life. We strive to continually improve the environments in which we live, and recognize the impact that buildings have on both the environment and their occupants.
Environmental sensitivity is fundamental to our approach. Whether the project goal is LEED certification or increased energy efficiency, our team has the expertise and innovation required to find a sustainable solution to any project. We encourage clients to discuss their goals at the earliest stages to maximize the benefits of their investment in sustainable architecture.
A distinctive service that D|A provides is our expertise in the permit and approval processes with local Planning Boards, the Historic District Commissions, and area Municipalities, with a notable success rate for permits and approvals.
