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

What Home Addition Work Covers
Room additions encompass many different types of construction that involve everything from adding a single bedroom to full second-story additions. At their heart, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is different than remodeling, which stays inside the original layout.
These builds call for a collaborative approach that brings together architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions require so many interconnected trades, hiring a experienced builder who can oversee every step is the key to a smooth project.
Room additions are a great fit for homeowners who need more room but prefer to stay in place. They're also a popular choice for homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the process follows a well-defined set of phases that our builders have mastered through experience.
