Whether you're planning for a new bedroom, a functional office, or a sunroom, room additions are the answer.

What This Type of Project Involves
Room additions cover a wide range of projects that involve everything from building an attached garage to large-scale family room builds. At their foundation, room additions mean physically extending your home's existing structure — either horizontally or vertically. This is distinct from remodeling, which works within the original layout.
These projects call for a full range of trades that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions touch so many systems, working with a skilled construction team who can coordinate each phase is critical.
Room additions are commonly chosen by homeowners who want a dedicated space but want to keep their current property. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the approach follows a well-defined set of phases that our builders have refined over many years.
