Tailored Additions for Every Type of Home

Your home is unique, and your addition should be, too. We work with you to design a layout that fits your goals, your lot, and your existing architecture. Whether you want to build out into the yard or expand vertically with a second-story addition, our team ensures the new space looks and feels like it’s always been part of the house.

We offer additions of all types and sizes, including home offices, expanded living rooms, dining areas, and playrooms. We carefully match roofing, siding, windows, and interior finishes so the addition blends perfectly with your existing structure. It’s not just more space—it’s better space.

Second Floors, Primary Suites & Kitchen Additions

Do you need a more private retreat or extra room for your family? Our Beaverton clients often add new primary suites with walk-in closets, ensuite bathrooms, and sitting areas for comfort and privacy. We also help families expand their kitchens to create more counter space, larger islands, and better flow for cooking and entertaining.

Looking to go up instead of out? We specialize in second-story additions that add bedrooms, bathrooms, or bonus rooms while preserving valuable yard space. From structural assessments to finish carpentry, we take care of every detail to make sure your new space is both safe and stunning.

Garage Additions, Studios & Detached Structures

In need of a dedicated workspace or hobby area? We build garage additions, workshops, and detached studios that offer flexible, insulated space without disrupting your main living area. These custom additions are ideal for artists, musicians, remote workers, or anyone looking for a quiet place to focus and create.

We also construct detached ADUs (Accessory Dwelling Units) that meet Beaverton’s zoning guidelines. These units are perfect for multigenerational living, rental income, or guest accommodations. We guide you through the design, permitting, and build process from start to finish, helping you make the most of your investment.
