Our holistic vision includes both architecture and interior design.

An Integrated Approach

At the heart of our practice is an integrated approach to design, where architecture, interior design and technical systems work together. The studio is a creative lab where designers collaborate on the best solutions for each project’s unique needs. Just like a natural eco-system, almost every aspect of a building’s design affects its performance. Its orientation, landscape, placement of windows, location and lighting can all have an impact on the ultimate energy performance of the building.

Always the “A” Team

Collaboration is at the heart of DECA’s practice. We champion our clients’ visions, while expertly guiding them through the design process. We set high standards and meet them, not only for must haves like quality control, but for how we listen and communicate. DECA’s principals bring over 25 years of experience to every project, and they’re on the job from day one. If you work with DECA, you work with the “A” team, start to finish.

Sustainable Design, Rooted in Place

Our designs include the use of natural, locally-sourced materials wherever possible and emphasize an understanding of how people interact with built environments. Sustainability is an integral part of our approach — we help clients find sustainable strategies that make sense and provide lasting value. As evidence of our dedication, all of our architects are LEED accredited.

No Short Cuts

Our studio environment emphasizes research, attention to detail, and commitment to excellence — a creative think-tank that’s both flexible and solutions-driven. DECA’s high standards for technical documentation are key to our work. They help us achieve sustainable, modern designs that respond to context and improve the interaction between people and the spaces they inhabit.
