What Room Additions Involves
Room additions cover a wide range of projects that span everything from constructing a new bathroom to full second-story additions. At their heart, room additions mean physically extending your home's current floor plan — either horizontally or vertically. This is different than remodeling, which stays inside the current square footage.
These builds require a coordinated effort that involves 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 experienced builder who can coordinate each phase is the key to a smooth project.
Room additions are a great fit for homeowners who have outgrown their current layout but aren't ready to move. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a well-defined set of steps that our team have refined over many years.
