Toll Brothers, Tri Pointe plan 919-home community near Tomball

Two national homebuilders have assembled 445 acres along Telge Road, just north of the Grand Parkway, for a 919-home neighborhood, and the real test in northwest Harris County is whether the added growth will deepen the strain on affordability, traffic, schools and drainage or help relieve a housing market that still needs more options.

Toll Brothers purchased three parcels totaling nearly 160.5 acres, while Tri Pointe Homes bought five parcels totaling nearly 288 acres. The land came from eight different sellers and the tracts ranged from four acres to 113 acres, a patchwork that took about four years to assemble. Land Advisors Organization said the site had been hard and expensive to sell or develop one parcel at a time because of drainage challenges, which is why the larger plan matters as much as the home count.

The development is planned for single-family homes on lots ranging from 45 to 80 feet wide, with lakes, waterways, a recreation area and pocket parks. That combination points to a neighborhood likely aimed above the entry-level market, even as first-time buyers in northwest Harris County continue to look for anything within reach. Toll Brothers and Tri Pointe have already teamed up on other Houston-area projects, including Evergrove, a 911-acre, 1,655-home community near Richmond in Fort Bend County.

The Tomball-area site sits about 32 miles northwest of downtown Houston in a corridor that has kept filling since the Grand Parkway segment north of U.S. 290 opened in 2016. The roadway was built to support demographic and economic growth, and the Telge Road site now sits in the middle of that same pressure. Nearby developments include Amira to the west near Mueschke Road, the Grand at 249 retail project to the east and the Interchange 249 business park south of the Grand Parkway.

Schools will also be part of the equation. Tomball Independent School District serves portions of Harris and Montgomery counties and had 23,271 students in the most recent enrollment data cited, spread across 25 campuses. The district’s growth has tracked the same housing boom that pushed builders deeper into northwest Harris County, where road access and school capacity remain key selling points.

Drainage may be the most important issue of all. The Harris County Flood Control District says the Willow Creek watershed is in northwest Harris County and drains about half of the City of Tomball, a reminder that every new subdivision in the area adds pressure to systems already tied to flooding risk. Toll Brothers and Tri Pointe expect to break ground in late 2026 or early 2027, but the question for Tomball is whether this 919-home project becomes part of the solution or another layer of growth to manage.
