What Room Additions Covers
Room additions encompass many different types of construction that involve everything from constructing a new bathroom to large-scale family room builds. At their heart, room additions require adding to your home's existing structure — either upward. This is different than remodeling, which works within the original layout.
These builds demand a collaborative approach that involves architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, hiring a general contractor who can coordinate each phase is critical.
Room additions are ideal for homeowners who want a dedicated space but aren't ready to move. They're frequently selected for families welcoming new members. Whether it's a small bump-out or a full-scale addition, the work follows a structured set of steps that our team have executed on hundreds of projects.
