A
former 63-acre office campus in Littleton, just south of Denver, has been transformed into a major development project. Republic Investment Group purchased the Lumen Technologies campus for $50 million, or $793,651 per acre, from Qwest. The property will be demolished to make way for new construction.

    The deal involved several transactions: Costco acquired 18.5 acres for $5.8 million, or $313,514 per acre, and plans to build a retail store, tire center, and gas station by 2026. Embrey, a multifamily developer, bought 17.5 acres for $17.1 million, or $977,143 per acre, and will construct a 370-unit luxury apartment complex called The Sullivan.

    The Sullivan will feature one-, two- and three-bedroom units, including 19 affordable options, as well as various amenities such as a clubhouse, fitness center, and resort-style pool. Embrey expects to break ground early next year, with the first units available in fall 2026 and completion expected by 2027.

    The City of Littleton has partnered with Republic Investment on an economic development project called Mineral Place, which will include retail and housing. The city has agreed to provide a $29.5 million share-back sales tax deal, and Costco's construction is expected to be completed by 2026.
