Whether you're ready to build a new bedroom, a functional office, or a guest suite, room additions are the answer.

What Home Addition Work Entails
Room additions encompass many different types of construction that span everything from building an attached garage to large-scale family room builds. At their foundation, room additions require adding to your home's existing structure — either horizontally or vertically. This is distinct from remodeling, which stays inside the current square footage.
These projects call for a coordinated effort that combines architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions involve multiple building disciplines, working with a general contractor who can coordinate each phase is essential.
Room additions are commonly chosen by homeowners who need more room but prefer to stay in place. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a clear set of phases that our team have refined over many years.
