What This Type of Project Entails
Room additions are a broad category that include everything from building an attached garage to major kitchen expansions. At their core, room additions involve expanding your home's existing structure — either upward. This is different than remodeling, which works within the current square footage.
These undertakings demand a coordinated effort that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions involve multiple building disciplines, choosing a skilled construction team who can manage all of it is critical.
Room additions are ideal for homeowners who want a dedicated space but prefer to stay in place. They're often the right move for families welcoming new members. No matter the size, the work follows a structured set of stages that our team have mastered through experience.
