The FabLab House Project (www.fablabhouse.com) is now undertaking construction phase in IAAC main hall. The pieces are being constructed in IaaC and will be transported to Madrid grouped together. The major structure (the machine room and first floor ground areas) have already been constructed, including the roof top sections, making it easier to make the paneling of the roof before putting it up on the structure. Other parts are also being assembled, at a very fast phase. This assembly will go on through out the month to get it prepared for the Solar Decathlon Europe Competition (www.sdeurope.org), which will take place in Madrid in June 2010.
