What Home Addition Work Covers
Room additions encompass many different types of construction that include everything from building an attached garage to full second-story additions. At their heart, room additions involve expanding your home's existing structure — either upward. This is different than remodeling, which reconfigures the existing walls.
These projects require a coordinated effort that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, hiring a experienced builder who can coordinate each phase is the key to a smooth project.
Room additions are ideal for homeowners who want a dedicated space but aren't ready to move. They're also a popular choice for multigenerational households. No matter the size, the work follows a well-defined set of steps that our team have mastered through experience.
