Octatube generally produce their space frames in round or rectangular section steel tube, but aluminium, solid timber and even cardboard and bamboo have been successfully used on occasion. The shift in construction philosophy away from a manufacturer-centred and towards a consumer-centred approach has moved the focus from industrial space frame manufacture to special, project-related design. The consequence is that many space frame designs do not fit in with any existing system. A large number of basic systems can certainly be designed, and projects often use a derivative of one of these.
Octatube included a supporting Tuball structure in hot galvanised steel in the South and East conservatory for the faculty of Architecture at the TU Delft. As well as delivering a lightweight structure, the standard Tuball system used also allowed the design & build project to be completed in just three months, despite severe winter weather conditions. The two new atria are constructed against the existing facade of the university’s brick-built former main building on the Julianalaan in Delft, dating from the start of the twentieth century and renovated by Braaksma & Roos Architects of Den Haag. The steel structural elements are optimally protected against corrosion by a hot galvanising process. The South conservatory has a floor area of 1500 m2, the East conservatory is 900 m2. Large-scale activities like the maquette shop and workshops for students are housed in these atria, which provide light and transparency in an otherwise rather enclosed building.
