"Potaarde" project is an innovative development located in Berchem-Sainte-Agathe, a green and picturesque district of Brussels. This small-scale project comprises 10 high-quality apartements and offers many advantages. The project is an example of investment in Future Proof building and environmentally responsible living, with the added benefit of considerable savings on energy and water costs. L'Etoile Verte is equipped with solar panels that cover +/- 40% of energy needs. Excess energy is sold, reducing communal costs. All flats have triple drainage and a rainwater recovery system for the toilets (+/- 20% of water consumption). Each flat has its own cellar and parkingspot.
