About This Service
Custom ADUs Built for How You Want to Use Your Property
An ADU gives you more usable space without having to move. Whether you want a detached guest house, a backyard apartment, an in-law suite, or a flexible living space, Gage Construction can help you build an ADU that feels intentional, durable, and connected to your long-term goals.
We work with homeowners throughout Central Texas to create custom ADU solutions that improve property function, support changing family needs, and add value over time.

What We Do
Interior & Exterior Residential Remodeling Services
Create a separate living space on your property for guests, family members, rental use, or added flexibility. Detached ADUs can include bedrooms, bathrooms, kitchens, living areas, storage, and private entrances.
Build a comfortable guest house that gives visitors privacy while keeping them close to your main home. These spaces can be designed for weekend guests, extended family, or long-term use.
Support multi-generational living with a custom in-law suite designed for comfort, accessibility, and independence. We can help create a space that works well for parents, adult children, or family members who need their own private area.
Turn an existing garage into usable living space, a studio, home office, apartment, or guest suite. Garage conversions can be a practical way to add function without building a fully detached structure.
Create a quiet, separate space for work, creativity, hobbies, or personal use. A custom backyard studio can give you separation from the main home while staying conveniently on your property.
Not every ADU needs to be large. We can help design and build compact, efficient living spaces that make smart use of square footage while still feeling comfortable and complete.
