The Verbiest single-family dwelling and artist studio in the Brussels municipality of Molenbeek is an example of how an alternative design of living spaces can guide a different use and behaviour of the residents, resulting in lower energy consumption. Instead of wrapping the former warehouse in polyurethane, the architect – who also owns and occupies the house – opted for a low-tech approach, which after careful calculations also has the greatest impact. Only the essential parts of the living space are heated: the kitchen, bathroom, a small living area and the bedrooms. In-between, spaces arise that evolve with the seasons: an office, an extra lounge area, a winter garden. The massive structure of the original industrial building retains heat in the autumn and is pleasantly cool in the spring. Or how the willingness to break fixed habits can lead to win-win situations in terms of energy and quality.
