What Home Addition Work Entails
Room additions encompass many different types of construction that include everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which works within the original layout.
These projects require a full range of trades that combines architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and final finishes. 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 have outgrown their current layout but aren't ready to move. They're frequently selected for homeowners planning to age in place. No matter the size, the work follows a structured set of phases that our builders have executed on hundreds of projects.
