The philosophy throughout all design projects is that simplicity is the most important element for success. A project should be timeless, elegant and functional. The juxtaposition between modern and traditional is carefully considered.

DHD Architecture & Design believes in creating continuity between the outdoor environment, the building structure, the indoor spaces and objects within. Design should create a seamless blend and subtle sensory experience as one moves throughout various spaces. Structures should respond to the site and utilize views, wind and light to its best advantage. Building mechanics can often include solar, geothermal or passive heating and cooling.

Projects can be full service from design, through construction and also include interiors. The firm has experience with primary and vacation residences in the city, country, mountains and on the coast. Commissions can extend into product design as well.
