Lahagu Housing Project

Lahagu Housing Project

The Lahagu Housing project is an affordable housing development in Tamale, Ghana. Developed by Reall, a leading international real estate developer, the project highlights that homes that are climate-smart can also be affordable. It gives low-income customers the opportunity to get on the Ghanaian housing ladder, and also encourages developers to see the value of building green homes.

The project consists of 100 two-bedroom green affordable homes developed by Afreh Group achieving 34% improvements in energy efficiency, 31% improvements in water efficiency, and 56% improvements in embodied energy in materials, as compared with conventional local construction methods. The contractor has achieved improved green performance through measures such as low-flow water fittings, walls built with compressed earth blocks, and naturally ventilated spaces.

The Lahagu Housing Project is the first EDGE-certified project in Northern Ghana. Reall and Afreh Group have brought in best practices from the construction sectors in both Ghana and the UK to deliver a product which is affordable, climate-smart and attractive to the Ghanaian customer. This project was delivered for the benefit of the Tamale Community Cooperative Credit Union, and serves as a demonstration of what can be delivered in the Ghanaian market. Local mortgage providers such as First National Bank, Stanbic and Absa have all expressed a keen interest in this kind of product and the opportunity it represents for engaging with whole new market segments while delivering on climate commitments.

The Lahagu Housing Project has received Final EDGE Certification from Sintali-SGS.
