Whether you're ready to build a new bedroom, a functional office, or a guest suite, room additions are the answer.

What This Type of Project Covers
Room additions are a broad category that include everything from building an attached garage to large-scale family room builds. At their core, room additions mean physically extending your home's footprint — either upward. This is not the same as remodeling, which works within the existing website walls.
These projects require a coordinated effort that combines architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions require so many interconnected trades, choosing a skilled construction team who can manage all of it is critical.
Room additions are a great fit for homeowners who need more room but prefer to stay in place. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a clear set of phases that our builders have executed on hundreds of projects.

During your planning session, we give you a clear breakdown specific to your project.
What's the typical timeline for room additions?A typical room addition build spans four to twelve months from permit approval to final inspection. Custom or specialty additions may take longer. City review and approval often accounts for a noticeable share of that overall timeline.

What's the difference between a room addition and a home remodel?A new-room build adds to your home's existing size by extending the structure beyond the current walls.

How do you make a new addition look like part of the original home?Matching the existing home is one of our core goals on every room addition project.
