What This Type of Project Involves

Room additions are a broad category that span everything from adding a single bedroom to large-scale family room builds. At their heart, room additions mean physically extending your home's existing structure — either horizontally or vertically. This is different than remodeling, which stays inside the original layout.

These undertakings call for a coordinated effort that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, choosing a general contractor who can coordinate each phase is essential.

Regardless of the scope, the work follows a structured set of steps that our builders have executed on hundreds of projects.
