Our Home Addition Services
We handle all types of home additions—from concept to completion:Room Additions
Need a new bedroom, guest suite, or home office? We design and build custom room additions that integrate beautifully with your home’s existing structure—inside and out.
Second Story Additions
Maximize your property’s footprint by building up instead of out. Our second-story additions add significant living space without reducing your yard size, and we ensure the structural integrity of your home remains intact during the process.
Kitchen Expansions
If your kitchen feels cramped or outdated, an expansion can add space for new appliances, more storage, and open-concept layouts. We create kitchens that are functional, modern, and perfect for entertaining.
Bathroom Additions
A new bathroom can make daily life more convenient, especially for growing families or guests. We handle everything from layout design to plumbing and finishing.
Garage Conversions & ADUs
Turn your garage into a livable, permitted space, or let us help you build a separate accessory dwelling unit (ADU) in your backyard. These additions are perfect for multigenerational living, rental income, or a private workspace.
Sunrooms & Enclosures
Want to enjoy more natural light or create a quiet retreat? We design sunrooms, covered patios, and enclosed porches that are comfortable year-round.
