What This Type of Project Involves
Room additions cover a wide range of projects that involve everything from adding a single bedroom to major kitchen expansions. At their core, room additions require adding to your home's existing structure — either horizontally or vertically. This is different than remodeling, which reconfigures the current square footage.
These projects call for a coordinated effort that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, choosing a experienced builder who can oversee every step is the key to a smooth project.
Room additions are commonly chosen by homeowners who have outgrown their current layout but prefer to stay in place. They're also a popular choice for multigenerational households. Regardless of the scope, the approach follows a well-defined set of stages that our builders have mastered through experience.
