More space, built to match your home
A room addition adds square footage, such as a bedroom, family room, or expanded living space, designed to work with your home’s existing structure and style.
We manage room additions from planning and permitting through framing, systems, and finishes, coordinating each trade along the way.

Room Additions FAQ
Answers to common questions about adding space to your home.
What’s involved in adding a room to my home?
A room addition typically involves design planning, permitting, foundation and framing work, and finishes, coordinated as one project.
Do room additions require permits?
Yes. Room additions require permits, and we manage that process as part of the project.
Can a room addition match my home’s existing style?
Yes. We design additions to tie into your home’s existing structure, rooflines, and finishes where possible.
How long does a room addition take?
Timelines depend on size, design complexity, and permitting. We provide a project-specific timeline after assessment.
Is a room addition different from an ADU?
Yes. A room addition expands your existing home’s footprint, while an ADU is typically a separate living unit. We can help you determine which fits your goals.
