Whether you're dreaming of a new bedroom, a functional office, or a guest suite, room additions turn that vision into reality.

What Room Additions Involves
Room additions encompass many different types of construction that span everything from adding a single bedroom to full second-story additions. At their foundation, room additions involve expanding your home's existing structure — either upward. This is distinct from remodeling, which works within the existing walls.
These undertakings require a coordinated effort that brings together architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions involve multiple building disciplines, choosing a skilled construction team who can manage all of it is the key to a smooth project.
Room additions are commonly chosen by homeowners who need more room but aren't ready to move. They're often the right move here for homeowners planning to age in place. Regardless of the scope, the work follows a well-defined set of stages that our builders have executed on hundreds of projects.
