The Block

The Block

The Block is an affordable housing complex being developed in Bellville, in the eastern metropolitan region of Cape Town, South Africa. Developed by Transcend Residential Property Fund, a South African real estate investment and development company, the project will retrofit 253 existing housing units. The units will be upgraded to a higher efficiency standard through the incorporation of technologies such as water-efficient plumbing features, reflective paint for roofs and walls, energy-efficient glass, heat pumps for hot water generation, LED lighting using lighting controls and smart electricity meters.

The project is part of the wider strategy of Transcend to invest in affordable housing across South Africa. Projects are located close to job opportunities, transport corridors and other amenities such as schools.

The Block has received a Preliminary EDGE Certificate from Green Building Council South Africa.
