What This Type of Project Covers
Room additions encompass many different types of construction that span everything from adding a single bedroom to full second-story additions. At their heart, room additions mean physically extending your home's existing structure — either outward. This is distinct from remodeling, which works within the original layout.
These builds call for a coordinated effort that involves architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, working with a general contractor who can oversee every step is essential.
Room additions are ideal for homeowners who need more room but want to keep their current property. They're often the right move for homeowners planning to age in place.
