Possibly one of Africa’s most sustainable buildings, the Hemp House has an incredibly light carbon footprint and is nothing short of genius. Created by Tony Budden and Duncan Parke, the House is made largely from Hemp – a commonly used term for high-growing varieties of the Cannabis plant. This versatile super plant can be converted into countless materials, including paper, textiles, biodegradable plastics, and fuel. The house itself is partially powered by solar energy, passively cooled, heated, and ventilated.
The floors are made from sustainably-sourced cork, 85% of the furniture and cabinetry is made from hemp-board, and all of the grey and black water will be treated and recycled. It is also fitted with LED lamps to reduce energy use, reclaimed stone and eco-paints are used to prevent harmful off-gassing. The internal modular walls are comprised of hemp insulation and sealed with magnesium oxide boards, while the external walls are made from a lime-based “hempcrete” that is considerably less energy intensive to produce and less dense than traditional cement.
