Whether you're ready to build a new bedroom, a expanded living area, or a sunroom, room additions are the answer.

What This Type of Project Entails

Room additions are a broad category that span everything from adding a single bedroom to full second-story additions. At their core, room additions require adding to your home's existing structure — either horizontally or vertically. This is distinct from remodeling, which reconfigures the existing walls.

These projects require a full range of trades that brings together architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and final finishes. Because room additions touch so many systems, hiring a general contractor who can coordinate each phase is critical.
