What This Type of Project Entails
Room additions encompass many different types of construction that span everything from read more adding a single bedroom to full second-story additions. At their heart, room additions involve expanding your home's existing structure — either upward. This is distinct from remodeling, which works within the original layout.
These builds call for a coordinated effort that brings together architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and cosmetic detailing.
