What Home Addition Work Covers
Room additions are a broad category that include everything from building an attached garage to full second-story additions. At their core, room additions involve expanding your home's existing structure — either outward. This is not the same as remodeling, which stays inside the original layout.
These builds call for a full range of trades that brings together architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, choosing a experienced builder who can oversee every step is essential.
Room additions are commonly chosen by homeowners who need more room but aren't ready to move. They're also a popular choice for families welcoming new members. No matter the size, the process follows a well-defined set of stages that we have mastered through experience.
