What Home Addition Work Covers
Room additions are a broad category that span everything from building an attached garage to full second-story additions. At their core, room additions mean physically extending your home's current floor plan — either outward. This is different than remodeling, which reconfigures the existing walls.
These builds demand a collaborative approach that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions require so many interconnected trades, hiring a general contractor who can coordinate each phase is critical.
Room additions are a great fit for homeowners who need more room but prefer to stay in place. They're frequently selected for homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the approach follows a structured set of stages that we have refined over many years.

During your planning session, we provide a detailed estimate specific to your goals.
What's the typical timeline for room additions?Most room additions runs approximately four to twelve months from breaking ground to move-in. Multi-room or second-story additions can extend the timeline. Getting permits through often accounts for a large chunk of that total schedule.
