Whether you're dreaming of a new bedroom, a functional office, or a dedicated workspace, room additions turn that vision into reality.

The result is a more comfortable home that works for your family for the long haul.

What Room Additions Covers
Room additions cover a wide range of projects that include everything from building an attached garage to full second-story additions. At their foundation, room additions require adding to your home's existing structure — either outward. This is not the same as remodeling, which stays inside the existing walls.
These projects demand a collaborative approach that involves architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions involve multiple building disciplines, working with a experienced builder who can manage all of it 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 families welcoming new members. Regardless of the scope, the work follows a well-defined set of steps that we have mastered through experience.
