What This Type of Project Entails

Room additions encompass many different types of construction that involve everything from adding a single bedroom to full second-story additions. At their heart, room additions require adding to your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the original layout.

These builds demand a collaborative approach that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions involve multiple building disciplines, working with a experienced builder who can manage all of it is the key to a smooth project.

Room additions are commonly chosen by homeowners who have outgrown their current layout but want to keep their current property. They're also a popular choice for families welcoming new members. Regardless of the scope, the work follows a well-defined set of phases that we have executed on hundreds of projects.
