DESCRIPTION:In our paper we will use our Stadthaus scheme to demonstrate t
 hat solid timber construction is a financially viable\, environmentally su
 stainable and beautiful replacement for concrete and steel in high-density
  housing.\n\nConstructed entirely from cross-laminated timber from the fir
 st floor upwards\, Stadthaus is the tallest timber residential structure i
 n the world. The nine-storey building is the first of this height to const
 ruct load bearing walls\, floors and cores entirely from timber. The tower
  houses twenty-nine apartments with a neighbour office on the ground floor
 .\n\nStadthaus was assembled using a structural cross-laminated timber pan
 el system produced in Austria by KLH. Each panel is produced from Spruce p
 lanks glued together with a non-toxic adhesive. The waste timber is conver
 ted to fuel\, which powers both factory and local village. As the prefabri
 cated panels arrived on site they were immediately craned into position an
 d fixed in place. Four carpenters assembled the eight-story structure in t
 wenty-seven days. The speed of the construction was especially relevant on
  the densely populated environment\, was the lack of noise and waste\, cre
 ating far less intrusion on the local community that a traditional concret
 e frame construction. The entire building was completed within forty-nine 
 weeks of starting on site\, estimated to be a saving of five months over a
  national concrete frame building. This method of construction is also inc
 redibly accurate\, and a healthy environment to both work on and live in. 
 Upon its completion the building had zero defects and 100% tenant’s appr
 oval.\n\nThe unique structure of the building is a result of the practice'
 s research in reducing the carbon emissions not only of the finished build
 ing but of the whole build process. The production of concrete and steel a
 re very energy intensive\, pumping tons of carbon dioxide into the atmosph
 ere. In complete contrast timber stores carbon as it grows\; our research 
 shows that Stadthaus stores 186 tones of carbon with its structure for its
  lifetime.\n
