What This Type of Project Involves
Room additions cover a wide range of projects that include everything from building an attached garage to full second-story additions. At their heart, room additions require adding to your home's footprint — either upward. This is different than remodeling, which reconfigures the existing walls.
These undertakings require a collaborative approach that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions involve multiple building disciplines, working with a skilled construction team who can manage all of it is critical.
Room additions are commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. 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 mastered through experience.
