What This Type of Project Involves

Room additions encompass many different types of construction that span everything from building an attached garage to large-scale family room builds. At their foundation, room additions require adding to your home's existing structure — either upward. This is different than remodeling, which reconfigures the current square footage.

These undertakings call for a full range of trades that involves 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 experienced builder 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 families welcoming new members. No matter the size, the process follows a well-defined set of steps that our builders have executed on hundreds of projects.
