An innovative housing pilot project has been launched in Mamelodi, east of Pretoria. An environmentaly-friendly structure is erected over an existing shack ensuring that the shack-owner does not have to relocate while their shack is being converted into a house. Tshwane Executive Mayor, Kgosientso Ramokgopa, says the coverted shacks, dubbed "the Lighthouse", take only four weeks to complete. The double-storey "lighthouse" which is rodent-proof also comes with superior thermal and acoustic features. Maluti Obuseng reports
