People are happier in a green environment than in grey surroundings! Between the pavers, we planted some creeping thyme, and put a little plum tree in their small yard! An herb garden and downspout garden was a must-have for these excellent chefs. By building a living roof, we climate-proofed this laneway.A green roof provides a rainwater buffer, purifies the air, reduces the ambient temperature, regulates the indoor temperature, saves energy and encourages biodiversity in the city.
