Klare, schöne Proportionen machen dieses Strohballenhaus in Ijburg zu einem kleinen Juwel
Die Baubeschreibung im Original: „This house can be seen as the culmination of SB building experience in the Netherlands, ‚State of the Art 2005‘ The site Steigereiland, part of IJburg, is interesting all by itself. The intention of the town council Amsterdam is to give prospective owners much more freedom to realise their dreamhouse then is usual in the closely regulated building practice in the Netherlands. This house breaks the mold in quite a few ways one of which is by being a SB building in a high density city environment. Baling started on 6th June 2005. August turned out to be a very wet high summer. Therefore about 40 bales had to be replaced. This seemingly daunting task (some of the bales were right at the bottom of the wall) turned out to be much easier then expected. Due to the horizontal pinning of the bales (2 per bale through the posts) we could easily remove only wet bales (>20%) without upsetting the bales above. Re-inserting new bales also turned out to be quite easy using hardboard slips and a heavy ‚persuader‘ wooden hammer. What suprised me is that bales quite easily absorb large amounts of water without raising moisture levels in the bales directly below. Obviously this only applies to short term wetting such as a few weeks. Using a hay bale moisture meter turned out to be quite essential to determine if bales were wet. Careful probing with the meter found another 8 bales just below the roof beams that had to be replaced. We found that it is essential to probe along the whole length of a bale to determine if it is wet. We removed some bales that had just 2 flakes above 20% with the rest well below 14%.“
