"We used plywood as shelving and for room partitions. On the balcony, we used double-stick mats usually used for fences. In the foreground, you can see a table designed by us. It's made of a very thin and light aluminum material also used for facades. We are architects, and we designed and built our home using an ecological approach. We were the first in Vienna to use straw bales as insulation material for our house."
