What Room Additions Involves
Room additions are a broad category that involve everything from building an attached garage to large-scale family room builds. At their core, room additions require adding to your home's existing structure — either upward. This is different than remodeling, which stays inside the current square footage.
These builds call for a full range of trades that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, hiring a skilled construction team who can oversee every step is the key to a smooth project.
Room additions are a great fit for homeowners who need more room but want to keep their current property. They're also a popular choice for multigenerational households. Whether it's a small bump-out or a full-scale addition, the approach follows a structured set of stages that we have executed on hundreds of projects.
