What Home Addition Work Covers
Room additions encompass many different types of construction that include everything from building an attached garage to major kitchen expansions. At their heart, room additions require adding to your home's existing structure — either horizontally or vertically. This is different than remodeling, which stays inside the existing walls.
These builds call for a coordinated effort that brings together architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, choosing a skilled construction team who can oversee every step is essential.
Room additions are ideal for homeowners who need more room but prefer to stay in place. They're frequently selected for homeowners planning to age in place. No matter the size, the process follows a well-defined set of stages that our team have refined over many years.
