For the changing needs of single parents – affordable, sustainable and individual, thanks to the Matchbox modular system

The planning area’s eclectic character is the unique thumbprint of the urban development. Instead of a perimeter development, four separate buildings with eccentrically arranged staircases structure the site. On the ground floor, inserted structures are designated for special uses such as a kindergarten or a communal kitchen. The upper floors are slightly set back from the site’s boundaries, creating a continuous loop throughout the building. This loop gives children the freedom to roam the well-lit corridors – a convenient feature for the target group of single parents.

The additional spaces are tailored to the needs of small communities and range in size from small (a common room that can be used as a storage room for buggies, as a library, music room, etc., on each floor) to large (communal kitchen and children’s play area on the ground floor, communal garden on the upper floor). A mobility point and corresponding app also facilitate communal living, making it possible to quickly and easily borrow and share everything within the community, from a carrier bicycle to a drill.

The Matchbox modular system is perfectly suited to the changing needs of single parents. The floor plans of the units, which range in size from 33m2 to 100m2 and are generally two- or three-room flats, make the best possible use of limited space with maximum flexibility.

In addition, the modular system created by BWM ensures a high quality of living, thanks to continuous glazing, a ceiling height of 2.6m and generous outside spaces along the entire length of each unit. The cost-effective serial construction method and the space-saving form of delivery and unadulterated use of materials make the Matchbox system both intelligent and practical.

The free space encircling the buildings culminates in the courtyard, which is divided into different sections by means of plant curtains; shrubs, perennials, hedges and climbing plants afford the ground-floor units a reasonable degree of privacy. Inspired by the partnership with the City of Vancouver and the forest theme, a number of maple trees adorn the courtyard, a totem pole in the visual axis creates a sense of identity and children can play in the tepees on the playground.
