New Construction in Sunnyvale, TX

Sunnyvale, Texas builds new homes the same way it does everything else: slowly, deliberately, and on big lots. This is not a town where a national builder drops 400 rooftops in a cornfield. One-acre minimum zoning covers much of Sunnyvale's 16.5 square miles, which means fewer lots, bigger houses, and a new-construction market that looks nothing like the rest of the eastern Dallas suburbs. As of late 2025 there were only about 44 new-construction homes on the market here, and the median new-build sale price was about $1,125,000. If you want volume and $400K starter homes, Forney is 10 minutes east. If you want an acre, an A-rated school district, and a house nobody has lived in, this is the page.

What is actually being built

The short version: large single-family homes on large lots, and not many of them. The one-acre minimum shapes everything downstream. A builder who pays for an acre of Sunnyvale dirt is not going to put a 1,800 square foot tract home on it, so what gets built skews big, custom or semi-custom, and priced accordingly.

That also means supply is structurally limited. Sunnyvale is a town of roughly 9,300 people that has chosen low density on purpose, so there is no pipeline of thousand-lot master-planned communities behind the current ones. When a phase closes out here, it is genuinely gone. That scarcity is a big part of why Sunnyvale real estate holds its value the way it does, and why new-build pricing sits where it does.

A note before the details: inventory in a market this small moves fast, and this page does not track individual listings. Treat everything below as a map of the landscape, then verify current availability, pricing, and lot supply with each builder directly.

The builders

Five builders are active in town as of this writing:

• Windsor Homes
• Kindred Homes
• Drees Custom Homes
• Chesmar Homes
• Village Builders

The one community-to-builder pairing we can state plainly: Kindred Homes is building Las Brisas, the final phase of Stoney Creek, on roughly one-acre lots. Beyond that, we deliberately do not assign builders to specific communities here, because those assignments change as phases sell through. Call the builders, ask what they have in Sunnyvale specifically, and ask how many lots remain.

One transparency note: this site offers a Featured Builder sponsor slot on this page, and how that works is spelled out here; sponsorship never changes what we report. We are also not a brokerage and nobody here earns a commission on what you buy.

Where the building is happening

Las Brisas is the headline. It is the final phase of Stoney Creek, Sunnyvale's largest master-planned community, with Kindred Homes building on roughly one-acre lots. The word "final" matters: when Las Brisas closes out, new supply inside Stoney Creek ends, full stop. Buyers who want new construction inside that community are working against a finite lot count. Start with our Las Brisas guide and the broader Stoney Creek guide.

St James Park is the other named community with active new construction. See the St James Park guide for the neighborhood picture.

Scattered custom builds round out the market. Because so much of Sunnyvale is zoned for one-acre lots, individual owners buy land and build one-off customs around town. These rarely show up in builder inventory counts, so if that is your path, you are shopping for dirt first and a builder second.

The established neighborhoods, Stone Canyon and Homestead, are essentially built out. They matter to a new-construction shopper mainly as the resale comparison: what does a finished, landscaped, lived-in Sunnyvale house cost versus a new one?

What it costs

The median new-construction sale price in Sunnyvale was about $1,125,000 as of late 2025. That number deserves context rather than sticker shock: you are typically buying a large new house on an acre, in a town where the schools rate an A from the TEA and the overall median sale price already sits around $829,000. New construction here is priced as the top of an already expensive market, not as an outlier.

Budget beyond the base price the way you would anywhere: lot premiums, design-center upgrades, and landscaping an acre (which is a real line item, not an afterthought). Ask each builder what is included, what the incentive structure looks like, and whether they are offering rate buydowns, because those programs change month to month and we do not track them here.

New build vs resale in Sunnyvale

The honest framing: as of mid-2026 you pay roughly a $300K premium for new over the typical resale.

| Factor | New construction | Resale | | ------------ | ----------------------------------------------------- | -------------------------------------------------------------- | | Median price | About $1,125,000 (late 2025) | About $829,000 (June 2026) | | Supply | About 44 homes, 4 builders (late 2025) | Broader, but still a small town | | Where | Las Brisas, St James Park, custom lots | Stone Canyon, Homestead, older Stoney Creek phases, and beyond | | Trade-off | Pick your finishes, warranty, waiting on construction | Mature trees, established landscaping, move-in now |

Neither answer is wrong. Resale gets you an established street and often more house per dollar. New gets you the warranty, the floor plan you chose, and, in Las Brisas specifically, a shot at the last new lots Stoney Creek will ever have.
