Spring Hill, TN

June Lake is the largest mixed-use project in Spring Hill's history. Master-developed by Nashville-based Southeast Venture, it spans 775 acres on the Williamson County side of I-65 (off Buckner Lane) and carries an estimated construction value of more than $2.4 billion at full buildout, per a Cumming Construction Management assessment cited at the 2020 project announcement. The plan calls for roughly 2,900 homes, 3.9 million square feet of Class A office space, nearly 1.3 million square feet of retail and restaurant space, and 400 hotel rooms, all organized around an 11-acre lake and a walkable town center.

Ground was broken on June 3, 2021, with the first single-family homes starting construction in 2022. Signature Homes is the primary Phase 1 homebuilder (about 400 single-family homes and townhomes plus an amenity center on 86.5 acres), with a 28-home custom section, The Preserve at June Lake, by Tudor Building Group; Southeast Venture's own 227-unit Solstice multifamily community broke ground in late 2022 and welcomed its first residents in 2024. Ohio-based Lifestyle Communities has also announced a second multifamily project, LC June Lake, a 509-unit development next to the Hy-Vee on June Lake Boulevard, announced in January 2025 with a groundbreaking targeted for summer 2025. As of 2026, homes are selling and occupied across multiple phases and the town center remains under development, with announced or in-pipeline commercial tenants including Liberty Federal Credit Union (an approved ~6,800-sq-ft branch), a Goddard School, and Image Studios. The Williamson County side is zoned to Williamson County Schools, though attendance boundaries near June Lake are split by I-65 and have been subject to district rezoning. The project is paired with major road infrastructure, including the I-65/June Lake Boulevard interchange (Exit 55) and an approximately 2.25-mile extension of Buckner Road; developers describe the full buildout as a roughly 20-year horizon.

On the industrial side, GM's Spring Hill Assembly is one of General Motors' most significant U.S. plants. GM committed about $2 billion to transition the plant to build electric vehicles, beginning with the Cadillac LYRIQ, and in April 2021 GM and LG announced a separate $2.3 billion Ultium Cells battery plant in Spring Hill. In March 2026, the Ultium Cells joint venture announced a roughly $70 million retooling to add lithium-iron-phosphate (LFP) battery cells for energy-storage systems, recalling about 700 furloughed workers. In June 2026, GM announced an additional $275 million across the complex: $150 million at Spring Hill Assembly to prepare for a future internal-combustion Cadillac model and $125 million at the Spring Hill Global Propulsion Systems engine plant for its 2.7-liter turbo engine program. With added Chevrolet Blazer production slated to begin in 2027, GM has said Spring Hill is on track to become a five-vehicle operation.

For buyers relocating to Middle Tennessee, these projects explain much of what is changing in Spring Hill: June Lake is adding thousands of homes plus offices, shops, hotels and new road infrastructure on the Williamson County side of the city, while the GM and Ultium Cells campus anchors a large base of manufacturing employment on the Maury County side. Understanding which side of the I-65 / county line a neighborhood falls on matters for school zoning, taxes and commute, and both developments are actively under construction in 2026.
