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.

Our Design-Build Process

01 | PLAN AND EVALUATE
We begin with a focused conversation and a site assessment so we can understand your goals, your property, and your timeline. Our team reviews feasibility, zoning considerations, and architectural direction early so you know exactly what is possible on your lot. This stage gives you clarity before investing further and establishes a clear path toward a permitted, buildable ADU.
02 | DESIGN AND APPROVE
Once the direction is set, we coordinate architectural drawings, elevations, and the documents required for city and HOA review. Estate ADU manages communication with reviewers and guides you through each checkpoint so nothing feels uncertain. By the end of this phase, you have approved plans, accurate pricing, and a clear understanding of the next steps.
03 | BUILD AND COMPLETE
With permits secured, construction begins. Our team oversees scheduling, trades, quality, and communication from start to finish. Homeowners receive consistent updates and a predictable experience as the ADU takes shape. The result is a well built, thoughtfully planned accessory dwelling that supports your family’s needs for years to come.

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!

They transformed my vision into a beautiful, high-quality ADU on time and within budget. Their transparency throughout the process was refreshing, and I appreciated their honest advice on what would work best for my property. I highly recommend Estate ADU for anyone looking to build an Accessory Dwelling Unit—truly top-notch service!
