Fred Kummer’s plan for a condominium tower across the street from Clayton City Hall will have its first public hearing in front of the city’s architectural review board later this month.

Plans filed with Clayton also offered the first details on the design and specifications of HBE Corp.’s proposed development at the corner of Bemiston and Maryland avenues. The $175 million building would rise 21 stories and add 110 residential units to the booming seat of St. Louis County.

Plans call for 250 parking spaces in four levels of interior garage space, three of which would be below ground. There are no plans for street-level commercial space, though there would be green space added to the west side of the building.

Last week, HBE’s president, Kummer, 90, dropped plans for a hotel just to the west of the planned condo tower and will instead use it as a construction staging area while he and his team finalize plans for a future development phase, likely retail and restaurant-oriented. Working with Kummer on the project are Steve Smith, CEO of the Lawrence Group; F. Stafford Manion, president of Gladys Manion Inc.; and Clayton-based Castle Design.

HBE closed in February on the purchase of the northern half of the block bounded by Maryland, Bemiston and Central avenues, mostly owned by the Gershman family.
