Nashville-based development company Richland Building Partners is seeking to develop a Chestnut Hill site with a mixed-use building.

According to a document submitted to the Metro Codes Department, the company envisions an eight-story building with commercial space on the main level and seven floors of for-sale residential spaces. The address of the three-parcel 0.57-acre property — located about three blocks from downtown’s southern fringe and about three blocks northeast of Wedgwood-Houston — is 1020-1024-1026 Third Ave. S.
