A TpESTATE eco-home is a house built from interlocking stabilised soil blocks, with solar power and biodigester sanitation. The walls are pressed from local soil with 8–10% cement and dry-stacked. TpESTATE designs and builds them and sells them in its own estates. ### Can I buy a home in Sierra Leone from the diaspora? Yes. TpESTATE sells eco-homes to buyers abroad, and the Diaspora Investor Package is built for them: you buy an eco-home in a managed estate and Eco-Living Oasis can let it for you. Many buyers start with the Homecoming Tour or a visit to Kent. ### Where are TpESTATE's estates? TpESTATE has four estates in development: Kent, Mile-36, Gullah Paradise at Lungi and Dublin on Banana Island. Kent, the Eco-Living Oasis, opens officially on 14 November 2026. ### Do soil-block homes stay cool? They are designed to. Thick soil-block walls slow the movement of heat into the rooms, and TpESTATE's designs add deep shade and cross-ventilation. The aim is a home that stays comfortable without air-conditioning and when the power is out. ### How is an eco-home powered and supplied with water? Eco-homes are designed for solar power, and at Kent that means 5 kW for each home and 10 kW for the community, 85 kW in all. Water comes from local wells and a borehole. Kent is not carbon neutral: a generator still runs in two short daily windows, and becomes true backup when the national grid arrives. ### How does the carbon footprint of a soil-block wall compare with brick? Kent's walls come to about 54.5 kg of CO₂ per m³ of wall, against 642.9 kg for fired clay brick. They use 8–10% cement and no kiln or firing. ### How can I see an eco-home before I decide? Visit the Eco-Living Oasis at Kent, which opens officially on 14 November 2026, the same date as part of the Homecoming Tour.
