Union Park
Hillwood master-plan straddling US-380 with an on-site Denton ISD elementary and a 30-acre central park
Union Park is a Hillwood master-planned community on the Little Elm side of US-380, anchored by a large central park and a lifestyle-programming model similar to Hillwood’s other DFW developments. It is fully within Denton ISD, with an on-site elementary school and Ray Braswell High School directly across the highway. It was named the Dallas Builders Association Master-Planned Community of the Year in 2024. Homes are predominantly newer construction from a rotation of national and regional builders.

Check these before you offer
The trade-offs a listing will not mention. None of these are reasons not to buy here; they are the things worth pricing in.
- It is Denton ISD despite the Little Elm mailing address, and buyers who assume Frisco or Little Elm ISD from the address have assumed wrong. That is the thing to settle first.
- It is still building out in newer phases, so construction traffic continues and early resale competes with builders selling new alongside incentives.
- Large Hillwood master plans of this type commonly carry a PID or MUD that adds to the annual tax bill outside the list price. Establish the full tax picture for the specific lot.
- Amenities and programming are funded by mandatory dues, and a full-time lifestyle manager is a real recurring cost.
- US-380 traffic and the Tollway extension construction are both part of the daily reality here.
- Downtown Dallas is roughly 50 minutes, so this is a Frisco-and-north commute rather than a Dallas one.
