DeFlat Kleiburg is a housing redevelopment project in Amsterdam, the Netherlands, developed by KondorWessels Vastgoed with NL Architects and XVW Architectuur as the architects. The project transformed the former Kleiburg apartment block, originally owned by Rochdale, into a large-scale “klusflat” or DIY housing model, where residents purchased unfinished homes at a relatively low price and completed the interiors themselves.12
The project is notable for its scale and for the social idea behind it. According to KondorWessels Vastgoed, it became the largest DIY housing project in the Netherlands, with sales starting in March 2013 and the project fully sold out after two years.1 The concept was intended to make homeownership more accessible to creative buyers and hands-on renovators, while also strengthening community ties among residents.12
Kleiburg had been considered for demolition by its former owner, housing association Rochdale, but the redevelopment approach preserved the structure and gave it a new use.25 The project has also been recognised as an architectural and social success: it won the EU Mies Award in 2017, and was also highlighted in other 2017 design and architecture awards.1
