A former school in the Highlands neighborhood will be converted into a center for fitness-oriented businesses. Nuture bought the 20,700 square foot building at 2949 Federal Boulevard for $6.1 million, or about $294 per square foot. Plans call for a mixture of retail and office tenants, all offering products and services oriented to health and wellness. Nuture will also include a cafe. The seller of the former Escuela Tlatelolco was Alpine Partners.
