In the Poorterstraat district of Montfoort, a social housing area, GroenWest owned 92 single-family houses that had provided affordable homes for local families since the 1970s.
However, after almost 40 years, the houses had become worn and uncomfortable by 21st century standards. The shortcomings included draughty, gloomy interiors, soaring energy costs and a general lack of space.
GroenWest teamed up with the VELUX Group for a major renovation that would transform ten three-storey, 131 m2 homes into buildings that produce energy, offer excellent living conditions and provide maximum daylight. In other words − Active Houses.
The architects from BouwhulpGroep first added extra space and light by bringing the houses’ unutilised attics to life. Every attic was enlarged and became an entity of its own, resulting in a new room and a rooftop terrace, alongside a central stairwell with roof windows for improved distribution of daylight and fresh air. The ground floor, first floor and staircase were also remodelled to ensure that the daylight and air from above benefitted the entire house.
