What Home Addition Work Covers
Room additions are a broad category that span everything from adding a single bedroom to major kitchen expansions. At their heart, room additions involve expanding your home's existing structure — either outward. This is distinct from remodeling, which reconfigures the existing walls.
These projects call for a coordinated effort that involves architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions involve multiple building disciplines, choosing a general contractor who can oversee every step is essential.
Room additions are a great fit for homeowners who want a dedicated space but aren't ready to move. They're frequently selected for families welcoming new members. No matter the size, the process follows a well-defined set of phases that we have refined over many years.

How many months does a room addition project take?The average home addition project spans four to eight months from breaking ground to move-in. Custom or specialty additions may take longer. City review and approval can take up a noticeable share of that project length.

Is a room addition the same as a renovation?A new-room build physically expands your home's total square footage by extending the structure outside the existing floor plan. A remodel works within your current square footage without adding new area. Room additions usually require more complex construction than finish upgrades.
