Whether you're dreaming of a new bedroom, a larger kitchen, or a dedicated workspace, room additions turn that vision into reality.

What Room Additions Entails

Room additions encompass many different types of construction that span everything from constructing a new bathroom to major kitchen expansions. At their core, room additions require adding to your home's existing structure — either outward. This is different than remodeling, which works within the original layout.

These projects demand a full range of trades that brings together architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions involve multiple building disciplines, choosing a skilled construction team who can manage all of it is essential.

Room additions are ideal for homeowners who want a dedicated space but aren't ready to move. They're also a popular choice for multigenerational households. No matter the size, the approach follows a structured set of stages that our team have executed on hundreds of projects.
