What Room Additions Entails

Room additions cover a wide range of projects that span everything from constructing a new bathroom to full second-story additions. At their foundation, room additions require adding to your home's existing structure — either upward. This is different than remodeling, which stays inside the original layout.

These builds call for a collaborative approach that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions touch so many systems, choosing a general contractor who can oversee every step is critical.

Room additions are commonly chosen by homeowners who want a dedicated space but aren't ready to move. They're also a popular choice for families welcoming new members. Regardless of the scope, the approach follows a well-defined set of stages that our builders have mastered through experience.
