What Home Addition Work Entails
Room additions encompass many different types of construction that include everything from constructing a new bathroom to large-scale family room builds. At their foundation, room additions require adding to your home's current floor plan — either outward. This is different than remodeling, which stays inside the current square footage.
These projects demand a full range of trades that brings together architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions touch so many systems, choosing a general contractor who can coordinate each phase is critical.
Room additions are commonly chosen by homeowners who need more room but aren't ready to move. They're frequently selected for multigenerational households. No matter the size, the approach follows a clear set of phases that our team have executed on hundreds of projects.
