Carmel-based Leo Brown Group plans to break ground early next month on a $17 million senior-living community south of Keystone at the Crossing. The project, dubbed Traditions at Solana, will be within the new Solana at the Crossing residential community under development by locally based Milhaus Development. Milhaus, which is developing The Artistry project downtown, bought the unfinished $150 million South Carolina-themed community in May. It’s developed 336 apartments in 16 new buildings and three that remain from the ill-fated condo project. About a third of the units are leased, said David Leazenby, Milhaus’ vice president of predevelopment services. Meanwhile, Traditions at Solana will include two-bedroom independent-living units as well as an assisted-living area and memory-care wing. The first residents are expected to move into the community in the fall. Traditions at Solana will be managed by an affiliate of Leo Brown Group, Traditions Management, which operates 162 senior-living units within Indiana. Architects for Solana at the Crossing are locally based firms AET Inc. and Odle McGuire Shook Inc.
