Room Additions
Expand your living space with professional room additions
Stetson Contracting and Waterproofing builds room additions for homeowners throughout Southern California. When your home no longer fits your needs, a room addition lets you expand your living space without moving. We handle room addition projects from initial planning through completed construction, coordinating all the trades and details involved in extending your home.
What We Offer
Bedroom Additions
Add a bedroom to accommodate a growing family, create a guest suite, or add a primary bedroom with en-suite bath.
Living Space Expansion
Extend living rooms, family rooms, or dining areas to create more open and functional common spaces.
Bathroom Additions
Add a new bathroom to your home. Full bathrooms, half baths, and en-suites designed to complement existing floor plans.
Sunrooms & Enclosed Patios
Enclose or add covered outdoor spaces to create year-round usable rooms that connect to your yard.
Second Story Additions
Build upward when lot space is limited. Second story additions require careful structural planning and execution.
Bump-Out Additions
Smaller extensions that add square footage to a specific room without a full-scale addition.
Why This Matters for Your Home
A room addition is one of the most impactful improvements you can make to your home. It adds usable square footage that directly addresses your need for more space — whether that’s another bedroom, a larger kitchen, or a dedicated home office. Room additions are complex projects that involve foundation work, framing, roofing, and tying new construction into your existing home’s structure and systems. A licensed contractor ensures the addition integrates properly with your home and meets all applicable building codes.
