our vision

We are Yes Duffy Architects.


We use design to elevate and activate compassionate, community-focused solutions to the housing crisis.


We believe housing is a human right.


And as design activists, we are here to strengthen, collaborate with, and celebrate communities that share these passions and perspectives. 

We are experts in leveraging the diverse and ever-changing array of local and state laws promoting housing production in our region.


Our current projects effectively utilize SB330(Streamlining), Ab2011(Affordable Housing), AB1287(Density Bonus), SB4(Housing on Faith Lands), SB9(Lot Subdivisions) and many other state and local pro-housing laws aimed at rapidly addressing our housing crisis.


We also specialize in innovations rapidly providing housing such as modular, mass timber and off-site fabrication.
