A local tax department building provided construction components for the low rise highdensity housing project. Harvest mapping found two of the tax building’s towers were to be demolished, just a few steps away from the building site. The highly repetitive concrete façade elements contain 40% of the weight of the complex. This turns financial positions around: instead of taking its standard 19% tax rate the tax department instead added 40% to the project. By organising the houses as a terrace sunlight is maximised and the cars have covered spaces.
