What Room Additions Entails

Room additions cover a wide range of projects that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions mean physically extending your home's existing structure — either outward. This is not the same as remodeling, which reconfigures the existing walls.

These builds call for a full range of trades that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, wall systems, and final finishes. Because room additions involve multiple building disciplines, working with a experienced builder who can coordinate each phase is critical.

Room additions are ideal for homeowners who need more room but prefer to stay in place. They're also a popular choice for families welcoming new members. Regardless of the scope, the approach follows a well-defined set of steps that we have mastered through experience.
