Design, permits and build. One Dallas team.
Guest houses, in-law suites and home additions built to match your house. Most builders in Dallas can't get the permit. We can.
Build Your ADU →See Our Work →Estate ADU designs, permits and builds ADUs in Dallas, from backyard guest houses to garage conversions. We'll tell you what fits before you spend a dime.

Why families build
Most families call us after something changes. A fall. A parent who shouldn't live alone anymore.
Assisted living feels far away. Moving in together means nobody gets a door to close. An in-law suite or backyard guest house solves both. Mom gets her own front door and a zero-step entry. You get to walk over for coffee.
Growing family instead? Same idea. More room, same street. We build in Lakewood, the M Streets, Highland Park, University Park and across Dallas.
What we build
One team for the design, the permit and the build.
01
A full home in your backyard with its own bedroom, bath, kitchen and front door.
Explore →02
Room for a parent to live on their own, close enough to check in every day. Attached or detached.
Explore →03
Add up to 1,000 sq ft to an older Dallas home without losing what you love about it. We know how to tie into a 100-year-old house.
Explore →04
Turn the garage nobody parks in into a garage apartment or home office. Usually the fastest way to add a unit.
Explore →Process
You always know what happens next, what it costs, and who's responsible.
See the full process →We review your goals, your lot and zoning so you know what's possible before you spend more.
Drawings, elevations and every document for city and HOA review. Approved plans and accurate pricing.

About us
We help Dallas families keep the people they love close, with ADUs, in-law suites and additions that get permitted and fit the neighborhood.
Ryan Huston and Jeff Karr ran large commercial builds before starting Estate ADU. When they started, Ryan gathered every ADU bid he could find in Dallas. Some came in at double a fair price, and he kept meeting homeowners whose builder couldn't get a permit. So they built a team that focuses on ADUs and handles the permit for you, out of an office on Greenville Ave.


Where we build
We build in Dallas and the Park Cities, mostly in older neighborhoods where zoning and conservation district rules trip up other builders. Don't see your street? Call us. We'll tell you straight if we can help.

Client words
“We met with multiple companies to get quotes for our backyard tiny house. Jeff and his team were by far the most professional and gave us a competitive quote.”

Often, yes. In the City of Dallas, a backyard unit with a kitchen usually needs a special exception from the Board of Adjustment, unless your lot is in an ADU overlay. Highland Park and University Park have their own rules. We check yours for free.
Dallas ADU permit guide →Timing depends on your property, design and permitting. We'll discuss a timeline for your project during the lot check.
Yes. We prepare the drawings, file with the city, present at the Board of Adjustment if you need it and work with your HOA. It's the part most builders struggle with, and it's usually why families call us.
It should. We design around your roofline, materials and style so it looks like it was always there. In conservation districts like Lakewood and the M Streets, the city reviews that too.
Yes. Many Dallas families use a HELOC or a construction loan.
