A friend pointed this out to me in the Süddeutsche Zeitung the other day; four architecture practices were asked to come up with designs for a gingerbread house, including a specification (well, recipe) and construction drawings.
This is Berlin-based Graft Architects:
and Sauerbruch Hutton:
with others by Coop Himmelb(l)au, and Allmann Sattler Wappner Architekten, München.
PS – I wrote something slightly rude about Graft a while back, because I couldn’t understand their website, but I forgive anyone anything if there’s cake involved.
