With 12 storeys, a breathtaking view of Cape Town’s imposing Table Mountain and a minimal ecological footprint, the world’s tallest building made with industrial hemp is soon to open its doors in South Africa. Workers in central Cape Town are putting the finishing touches on the 54-room Hemp Hotel, which is due to be completed in June. “Hempcrete” blocks derived from the cannabis plant have been used to fill the building’s walls, supported by a concrete and cement structure. Hemp bricks are becoming increasingly popular in the construction world thanks to their insulating, fire-resistant and climate-friendly properties. Afrimat Hemp is now preparing to produce its first blocks made only with South African hemp. Hemp Hotel architect Wolf Wolf, 52, sees this as a game changer to make hemp buildings more widespread in this corner of the world.
