What Room Additions Entails
Room additions are a broad category that include everything from building an attached garage to full second-story additions. At their heart, room additions require adding to your home's existing structure — either outward. This is not the same as remodeling, which reconfigures the existing walls.
These builds call for a collaborative approach that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions touch so many systems, working with a general contractor 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 often the right move for families welcoming new members. Regardless of the scope, the work follows a well-defined set of stages that we have refined over many years.
