What Room Additions Entails
Room additions are a broad category that involve everything from building an attached garage to major kitchen expansions. At their core, room additions involve expanding your home's footprint — either outward. This is distinct from remodeling, which works within the current square footage.
These builds call for a collaborative approach that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions touch so many systems, choosing a general contractor who can manage all of it is critical.
Room additions are ideal for homeowners who need more room but aren't ready to move. They're also a popular choice for families welcoming new members. No matter the size, the process follows a well-defined set of phases that we have mastered through experience.
