This Wilhelminian style building, originally built in the 19th century and partially destroyed during WW2, was completely refurbished using dry-lining methods in order to create luxurious, new, residential flats. The most striking part is the addition of another floor in the place of the formerly empty attic. All flats were built according to the highest energy saving and sound absorption standards by using various Rigips dry-wall constructions with high-end plasterboard tiles. The greatest challenge was the dry-lining of the small towers with their height of 8 metres. It took a great deal of time to take the exact measurements and to install the substructure and the plasterboard tiles with the utmost accuracy. The implementation of the required light concept was a huge challenge too and in order to meet the rigorous project standards the final surface coating was realized with VARIO joint filler and ProMix Finish according to the highest standard (Q4).
