Architecture and Enclosure services
for new and heritage buildings

About us

I opened this practice to serve the needs of  Building Owners, Architects, Engineers, Contractors, and Real Estate Professionals who value sustainable, durable, and efficient  solutions for their projects. I focus first on understanding client and building needs, followed by developing practical solutions based on careful evaluation and assessment.  Together, we will find success.

Transformative enclosure solutions

making a

BEC+D is committed to transformative enclosure solutions for new and existing buildings. Design is a collaborative process with a focus on assessment, energy efficient enclosure upgrades, maintaining embedded carbon, and rehabilitation of heritage buildings. 

Existing buildings are the foundations of our communities. Even as our building stock evolves we honor the spirit of place while aiming for accessibility, walkability, safe streets, and vibrant contextual design.

New buildings will be here beyond our own lifetimes. We advocate that our clients work beyond code minimums to provide long term durability, and high performance building systems

Simply, we want all of our work to be part of the climate solution.
