What Home Addition Work Covers
Room additions encompass many different types of construction that include everything from constructing a new bathroom to full second-story additions. At their foundation, room additions mean physically extending your home's existing structure — either horizontally or vertically. This is not the same as remodeling, which stays inside the original layout.
These undertakings call for a full range of trades that combines architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, choosing a general contractor who can coordinate each phase is the key to a smooth project.
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 we have executed on hundreds of projects.
