What Room Additions Entails
Room additions encompass many different types of construction that include everything from building an attached garage to full second-story additions. At their core, room additions mean physically extending your home's existing structure — either outward. This is distinct from remodeling, which works within the current square footage.
These builds call for a collaborative approach that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions involve multiple building disciplines, hiring a experienced builder who can manage all of it is the key to a smooth project.
Room additions are ideal for homeowners who want a dedicated space but prefer to stay in place. They're also a popular choice for multigenerational households. No matter the size, the approach follows a well-defined set of phases that we have executed on hundreds of projects.
