When the Hohenstange primary school in Tamm became an all-day school, it needed more space. The architects of k+h Architekten who were contracted to design the extension opted for a sustainable and exposed support structure in BauBuche.
For architect Oliver Krause from k+h Architekten and structural engineer Jürgen Helber from Helber + Ruff, this was the first project in BauBuche.
Jürgen Helber (Helber + Ruff):
"The key advantage of the material is its excellent strength. In other projects, we are now considering BauBuche as a substitute for steel beams, and also use the timber material where small cross-sections are desired that cannot be achieved with conventional glulam elements. We think that there is a huge potential for BauBuche where needle beams and auxiliary beams are necessary and the construction height is limited. Such solutions have also many advantages for timber construction contractors, as all work can be done by the contractor himself, joints and connections can be established relatively easily, and there is no need for fire-protection coating. Also, BauBuche can be easily combined with other materials. Where deformation is a key factor, BauBuche might however not always be the best solution."
Oliver Krause (k+h Architekten):
"We were won over by the homogeneous look and surface finish of the material. Also, BauBuche is very hard and strong. Compared with other softwood products, there are much fewer knots. However, the fact that BauBuche is so hard and strong caused us some headaches when it came to the machining of the elements. On the other hand, in a school building, resistance to wear and tear is a huge advantage, and BauBuche is nearly as robust as concrete."
