DENVER – December 22, 2025 – McWhinney, a Colorado-based real estate investor and developer of commercial, multifamily, hospitality, residential, and mixed-use assets, and Livmark Communities, a developer specializing in multifamily and single-family for-rent communities, announced today the groundbreaking of Mountain Brook Flats, a new 200-unit luxury apartment community in Longmont, Colorado. The $71 million joint venture brings together Livmark’s experience designing high-quality, ownership-level communities and McWhinney’s long-term approach to executing and operating multifamily assets across the region.
“Mountain Brook Flats reflects the kind of opportunity that McWhinney looks for: well-designed communities where we can bring strong execution experience and make long-term investments in Colorado’s growth,” said Dani Sassower, Senior Vice President of Housing with McWhinney. “As housing preferences evolve, we’re focused on supporting more ways for people to live well across every stage of life, while continuing to invest in vibrant, sustainable communities along the Front Range.”
Located within the Mountain Brook master-planned community, the project spans nine acres and is strategically positioned just west of downtown Longmont, within walking distance of restaurants and retail along Hover Street and less than a 20-minute drive from downtown Boulder.
“We’re thrilled to introduce Mountain Brook Flats, a new standard of rental living for Longmont. These homes feature condo-level craftsmanship and design typically reserved for Colorado’s most upscale for-sale communities, paired with a best-in-class amenity package that truly elevates the resident experience. It’s unlike anything Longmont has seen before,” said Chris Beabout, Managing Partner at Livmark Communities.
Building on Livmark Communities’ experience designing similar floor plans for for-sale condominiums, McWhinney and Livmark aim to bring the same ownership-quality design to the rental market with Mountain Brook Flats. The 200-home community will feature 10 three-story, 20-unit buildings with one-, two-, and three-bedroom residences averaging just over 1,150 square feet. The apartment homes are designed for comfort and longevity, with high-quality finishes, oversized balconies and convenient garage parking. Residents will also share the new Mountain Brook Clubhouse, currently inclusive of a resort-style pool with swim lanes and a splash pad, a fitness center with yoga studios, an outdoor fireplace and seating area, a tavern lounge, tennis and pickleball courts and pocket parks that connect the community, with plans to add a dog park.
With Longmont’s CHIPS Zone designation, one of only two in Colorado, fueling investment in semiconductor and advanced manufacturing, the region is poised for continued growth in jobs and housing. Residents benefit from proximity to employers in technology, healthcare, and advanced manufacturing, including Google, IBM, Ball Aerospace, and UC Health — all while providing a more attainable cost of living than nearby Boulder and Denver.
“Longmont continues to experience strong population and employment growth, and Mountain Brook Flats is designed to meet that demand with larger units, elevated finishes, and in-demand amenities,” said Chad O’Connor, Vice President – Acquisitions & Development. “We’re proud to partner with Livmark Communities on a project that complements the broader Mountain Brook community and reinforces Longmont’s position as one of Colorado’s most desirable places to live.”
Construction of Mountain Brook Flats is scheduled to begin in December 2025, with lease-up anticipated to commence in 2027. Landmark Construction Solutions, a Livmark Communities-affiliated company, will serve as the general contractor.
