What Room Additions Entails
Room additions are a broad category that span everything from building an attached garage to large-scale family room builds. At their core, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which stays inside the original layout.
These projects call for a collaborative approach that involves architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim.

Room additions are ideal for homeowners who want a dedicated space but prefer to stay in place. They're often the right move for multigenerational households. No matter the size, the approach follows a well-defined set of steps that we have mastered through experience.
