This residential tower has been developed in collaboration with its future residents and a contractor on a building plot obtained from the Municipality of Amsterdam by a selection process. The 45 m or 12 floors high building forms the Southern part of a series of six equally collectively developed residential buildings and occupies an exposed site at the intersection between an abandoned harbor basin and a bridge in Buiksloterham, a former industrial harbor area in Northern Amsterdam.
Responding to the high ambitions for sustainable and circular development as defined by the municipality for this post-industrial district, Kavel 20A is combining a conventional structural system based on reinforced concrete in the plinth with a prefabricated, cross-laminated timber construction (CLT) in the tower. The CLT-walls are covered with fireproof plasterboard while the CLT-floors with 4,80 m span width and reinforced with a lime gravel layer for sound insulation remain exposed.
Aiming at providing habitat for humans and non-humans and thus defining an expanded collective, the building combines 35 dwelling and commercial with 70 vegetation units. The predominantly single-floor apartments are mixed with a few double floor lofts and have a wide range of size and entirely individualized layouts for diverse residents. The vegetation zones are exclusively double-height and occupy an outdoor zone articulated by a structural steel frame reminiscent of the location’s industrial past. The heterogeneous population of low-growing trees, shrubs, grasses and climbing plants is made of exclusively local species selected in terms of their quality for seasonal appearance and of their suitability for the environmental conditions of their particular residency within the building. Automated, computer-controlled, nutrition-enhanced irrigation completes this techno-organic assemblage.
