Welcome to our studio

The places in which we live our lives are more than a collection of buildings, parks and street grids; they are the context and the content of our collective experience. Places are a reflection of a deep relationship between man, land, air, water, and light. How people shape their place in the context of the local natural environment creates a rich fabric of traditions, patterns, and landscapes. Celebrating these is the essence of a community’s human connection to a place!

Great design grows from an abundance of listening and asking questions about a place’s human connection. A planning or design process is a means for telling powerful stories and celebrating a particular place and its people in a physical form. At EPD, we harness multi-disciplinary collaboration to make human, cultural and natural experiences that enrich the places we live in and visit. Since 1939, our firm has sought to give voices to places’ people, heritage and natural bounties.

Our firm name is the embodiment of our planning and design philosophy.  This philosophy is borne from man’s fundamental understanding of nature.  Our firm’s logo is based on the symbols used by early man to represent the essential elements of nature and is an abstract interpretation of primitive cave carvings found in Europe.
