Home Additions & Expansions in Dallas, TX
Thoughtfully designed home additions that create more livable space for your family without changing neighborhoods.
Expand Your Home with a Tailored, High-Quality Addition
While Estate ADU specializes in accessory dwelling units, some families need additional space within the main home rather than a separate structure. Our home additions and expansions are built with the same clarity, precision, and design-build oversight that defines our ADU work.
We help homeowners throughout Dallas — including Lakewood, Preston Hollow, East Dallas, University Park, and Highland Park — expand their existing footprint with carefully planned additions that respect the home's architecture and meet the needs of aging parents or extended family.
Whether it’s a suite addition, expanded living space, or a redesigned layout to support long-term comfort, our team handles the design, permitting, engineering, and construction from start to finish.
Seamless Integrations for Multi-Generational Living
Adding space is often the best solution for families who want to stay in their neighborhood but need a safer, more comfortable layout. Estate ADU focuses on expansions that improve functionality without compromising the charm of Dallas’s established homes.
We evaluate structural requirements, tying into existing utilities, roofline continuity, natural light, and long-term accessibility. The result is a tailored addition that feels intentional, not like an afterthought.

Trusted by Families Across Dallas
Great experience converting a detached garage into a Mother-In-Law Suite. Full kitchen, bathroom, shower and laundry n demand hot water. Punctual and well managed. Jeff and his crews take pride in their work. There was one minor issue with city permitting but it was quickly resolved and was at no fault of EADU. Highly recommend!
