Looking to add a casita, ADU, or guest house to your property? Ernie and his team design and build custom standalone living spaces for East Valley homeowners. With 35 years of experience and BBB accreditation, Custom Design Build & Remodel builds your detached space to fit your family, your home, and your lot.
Your property may have more potential than you think. An accessory dwelling unit, or ADU, is a self-contained living space built on the same lot as your home. Homeowners across Mesa, Gilbert, Chandler, Tempe, and the East Valley use them as guest houses, casitas, home offices, or private suites for family. Ernie works with you from the first sketch to the final walkthrough, so the finished building matches your home and the way you live.
An ADU is a building with its own living area, either attached to your home or standing on its own. A casita is a small, standalone version, often used as a guest house or a private retreat. A well-built ADU can include its own kitchen and full bathroom, so it lives like a true second home. As a licensed and insured contractor, Ernie and his team handle every part of the build. Whether you picture a quiet studio in the backyard or a full guest house, we design each project around your needs and your property.
A casita is one of the most popular ways to add comfort and value to your property. It gives visiting family and friends a private place to stay, and it can serve as a peaceful retreat or a flexible bonus space. If you are drawn to the tiny home lifestyle, we can build a compact, well-planned structure that still feels open and livable. Every casita is custom-built to your style, from a cozy guest suite to a fully finished tiny home.
More families are choosing to live close while keeping their independence. A mother-in-law suite gives a parent or loved one their own private space right on your property. We design these suites for comfort and easy access, with an open layout and thoughtful finishes. It is a warm way to keep family near without giving up privacy for anyone.
Beyond casitas and suites, we build custom standalone structures from the ground up. That starts with a solid concrete foundation, poured to support your new building for the long haul. Whether you are planning a detached studio, a backyard office, or a small custom home, Ernie and his team handle the full build, including the kitchen, bath, heating, and cooling, with the same care we bring to every remodel.
Framing is where your building takes shape. Our team frames every casita and ADU to be strong, square, and built to last through Arizona summers. We use quality materials and proven methods, and Ernie personally checks the work at each stage. The result is a structure that feels solid and finished, inside and out.
A detached building needs a roof that can stand up to the desert sun and monsoon season. We install durable roofing and seal your new structure against heat and weather, so it stays comfortable year-round. From the first framing to the final finish, we build your casita or ADU to protect what matters and to look right at home next to your house.
