The tramezzino is a: triangular Italian sandwich with the crusts removed and are popular and inexpensive. The origin of the tramezzino can be found in (Caffè Mulassano) in Turin where I worked for Andrea Bruno Architetto and where I also met both la Juve and Lingotto.  The tramezzino I understand to be a halfway, between breakfast and lunch but also between the triangle and the regular polygon. I like triangles. It reminds me of Polynesia as triangulation in navigation gives 3-point geo-spatial fixity. What happens if we triangulate the fibre cement sheet cladding on our proposal by cutting along the diagonals?

“Look mum, no hands!” Secret fixing is the architectural equivalent of riding your bike with no hands. That’s really not so difficult when actually “Look mum, doing a wheelie” is far more daring. Your hands are on the bike but the bike is being propelled at a balanced crazy angle. Even better is a rodeo-like one-handed wheelie. Trying to implement difficult architectural geometries made me question whether it is then necessary to complicate matters with the economic overlay of secret fixing which often requires curtain walling ‘cassette cladding’ diseconomies to create material strength through extruded depth. One could secret fix though through bonding: a triumph of the chemical over the mechanical. Or is it? How do the insurers / warrantors assess the fixation risk? Mechanical could puncture a waterproofing membrane for example. SuperGlue was promoted when I grew up as ‘one drop holds a tonne’ but these were laboratory conditions promoting tensile not shear strength. And who says the contractor applies the correct amount when cost cutting quantities increases profit? The name’s Bonded, James Bonded? Doubtful when he still uses a mechanically propelled weapon. So let’s keep it simple: a mechanical face-fixed stainless steel screw is relatively low-tech ‘8-bit solution’ for an easy fix without the need for an ‘Approved Installer’> given the affordability crisis affecting house building in London I am convinced this is the way forward.
