What Home Addition Work Covers
Room additions cover a wide range of projects that include everything from adding a single bedroom to major kitchen expansions. At their heart, room additions mean physically extending your home's current floor plan — either outward. This is not the same as remodeling, which stays inside the current square footage.
These builds require a collaborative approach that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions require so many interconnected trades, hiring a experienced builder who can manage all of it is critical.
Room additions are commonly chosen by homeowners who want a dedicated space but prefer to stay in place. They're also a popular choice for homeowners planning to age in place. No matter the size, the approach follows a well-defined set of stages that our team have executed on hundreds of projects.
