What Room Additions Involves

Room additions are a broad category that include everything from adding a single bedroom to full second-story additions. At their heart, room additions mean physically extending your home's current floor plan — either horizontally or vertically. This is not the same as remodeling, which reconfigures the existing walls.

These projects demand a collaborative approach that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, choosing a skilled construction team who can manage all of it is essential.

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 team have executed on hundreds of projects.
