Two students from the Technical University of Vienna came up with the concept for the "Robbiton" fairy tale playground: 1000 running meters of tree trunks, more than 50 bales of straw, 15 tons clay as well as two truck loads of substrate for green roofs constitute the scenic hang-out spot Robbiton.

OHW - Experience

Both houses are open to visitors, and anyone who is brave enough can also take a quick look at the roof. The tour takes in the wider plot. As new buildings are going up on site all the time, it is well worth visiting again. Children’s tours on Sunday 2-5pm. A chance to get to grips with architecture and building materials – literally and figuratively.
 We can reveal that noise abatement isn’t a concern at this particular location. Led by: AHDF
