What Room Additions Entails

Room additions encompass many different types of construction that span everything from adding a single bedroom to full second-story additions. At their heart, room additions involve expanding your home's existing structure — either outward. This is different than remodeling, which reconfigures the current square footage.

These builds call for a full range of trades that involves architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions involve multiple building disciplines, choosing a general contractor who can oversee every step is essential.

Room additions are ideal for homeowners who have outgrown their current layout but prefer to stay in place. They're often the right move for families welcoming new members. No matter the size, the process follows a clear set of stages that our builders have refined over many years.
