What This Type of Project Involves
Room additions encompass many different types of construction that include everything from constructing a new bathroom to large-scale family room builds. At their core, room additions require adding to your home's existing structure — either outward. This is distinct from remodeling, which reconfigures the existing walls.
These projects call for a collaborative approach that combines architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, choosing a skilled construction team who can coordinate each phase is the key to a smooth project.
Room additions are commonly chosen by homeowners who want a dedicated space but aren't ready to move. They're often the right move for homeowners planning to age in place. No matter the size, the approach follows a well-defined set of stages that we have refined over many years.
