Mattamy Homes has acquired the land for Twin Peaks Crossings, a 154-homesite community on the Twin Peaks corridor in Marana, Arizona. This is the builder's third active project in the area, joining Tavira at Twin Peaks and Silverbell Ridge, and it adds meaningful new inventory to one of the fastest-growing parts of the Tucson metro.
What Mattamy Homes Marana Arizona Is Building on the Twin Peaks Corridor
Twin Peaks Crossings sits on a corridor that has seen steady infrastructure investment over the past decade. The location gives residents direct access to Interstate 10, with Tucson and Oro Valley both close by. Nearby retail includes the Tucson Premium Outlet Mall, Oro Valley Marketplace, and La Encantada. The Dove Mountain area, known for championship golf courses and resort amenities, is also within easy reach.
Mattamy opened Tavira at Twin Peaks in September 2025 and Silverbell Ridge in February 2026. Adding a third community with 154 lots in the same corridor signals that the builder sees sustained demand here, not a one-time opportunity.
For context on how national builders evaluate land acquisitions, the National Association of Realtors tracks new construction activity as one of several leading indicators of local housing supply and demand.
What New Supply at This Scale Means for Nearby Homeowners
A 154-lot community does not flood a market overnight. Build-out typically stretches over two to four years, so the effect on nearby home values tends to be gradual rather than sudden. That said, homeowners within a mile or two of Twin Peaks Crossings should understand a few things.
New construction gives buyers a direct comparison point. If Mattamy prices its homes competitively, resale sellers nearby need to price accurately and present their homes well to compete. At the same time, new communities often raise the profile of a corridor, bringing more retail, services, and infrastructure that can support values across the broader area.

New construction in this price range typically carries builder incentives during the early sales phase, which is worth noting if your timeline aligns with a mid-to-late 2026 opening window.
