What Room Additions Covers
Room additions are a broad category that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions mean physically extending your home's footprint — either horizontally or vertically. This is not the same as remodeling, which stays inside the existing walls.
These undertakings require a collaborative approach that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, working with a general contractor who can coordinate each phase is critical.
Room additions are a great fit for homeowners who need more room but want to keep their current property. They're often the right move for families welcoming new members. Regardless of the scope, the work follows a structured set of stages that our team have executed on hundreds of projects.
