are a type of housing, they come in many shapes and sizes. We specialize in helping homeowners build beautiful, thoughtfully-designed cottages in their backyards.
Welcome your aging parents, or offer additional space for your kids to grow
We design, permit, and find the right build method to get your backyard dream home built. We have designed and permitted about 200 backyard cottages and built over 60 of them since 2008, before these were called ADUs. That makes us the most experienced ADU architects in the Bay Area.
We need to hear your goals and understand the potential and limitations of your yard to determine what type of ADU is best for you. We aim to keep the process fun and manageable, but we are building a whole house, so there is much to discuss!
Construction cost in general is around $450 - 700+ per sq ft. The smaller the ADU, the higher the cost per sq ft as you are adding all the expensive pieces of a big house in a small footprint. Other factors that may impact the price are: steep backyards or difficult access.
From the day you ask for our remote assessment, our average project take 9-12 months. Homeowners using our pre-designed plan sets tend to fall in the shorter end of that range, while fully custom jobs tend to fall toward the higher end of that range.
Our clients love knowing they could live in their ADU themselves, and take pride and
comfort knowing this home is designed to be multipurpose and multi-generational. We
work best with homeowners who appreciate thoughtful, breath-taking design.
