Whether you're planning for a new bedroom, a expanded living area, or a dedicated workspace, room additions are the answer.

What This Type of Project Entails
Room additions encompass many different types of construction that span everything from constructing a new bathroom to large-scale family room builds. At their heart, room additions require adding to your home's current floor plan — either outward. This is distinct from remodeling, which works within the original layout.
These projects require a full range of trades that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and cosmetic detailing. 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 want a dedicated space but want to keep their current property. They're also a popular choice for multigenerational households. No matter the size, the work follows a well-defined set of phases that our team have refined over many years.
