What This Type of Project Covers
Room additions encompass many different types of construction that span everything from adding a single bedroom to major kitchen expansions. At their core, room additions involve expanding your home's footprint — either upward. This is different than remodeling, which stays inside the current square footage.
These undertakings require a coordinated effort that involves architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions involve multiple building disciplines, hiring a general contractor who can coordinate each phase is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. They're often the right move for families welcoming new members. Whether it's a small bump-out or a full-scale addition, the work follows a well-defined set of stages that our team have executed on hundreds of projects.
