What This Type of Project Covers
Room additions are a broad category that span everything from constructing a new bathroom to full second-story additions. At their foundation, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the current square footage.
These undertakings require a full range of trades that brings together architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions touch so many systems, hiring a general contractor who can oversee every step is critical.
Room additions are a great fit 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 steps that our builders have executed on hundreds of projects.
