This office 
building provided a variety of spaces from group working areas to unit offices 
and conference rooms, using standard elements in readily available materials and 
prefabricated modules for conference rooms and sanitary areas. The envelope of 
the building consisted of 2 closed and 2 glazed facades. The four levels, which 
were square on plan and linked by a continuous, vertical open space that rose 
irregularly through the full height of the building. The three upper levels had 
the same layout, but were turned successively by 90 degrees, so that the line of 
access via the staircase was in a spiraling form. |

The steel 
structure comprises of steel primary beams I-section 270mm deep and columns 
I-column 220mm deep filled with concrete, with Ø 108/7.1 mm tubular steel 
compression members. The reinforced concrete slabs were prefabricated, and 
walkways were made of 8 mm sheet steel (120/60/5 mm steel RHSs). One of the 
closed façade used prefabricated concrete elements, 240 mm foamed-slag concrete 
façade elements with core insulation, painted grey. The steel staircases were 
also prefabricated and made of 120/60/5 mm steel RHS carriage. The sheet-steel
