Actually two separate, unrelated buildings, but both done for the Berlin IBA 1987, as part of the Neubau programme.
Both are at tourist ground zero in Berlin, and have understandably suffered from the grime and commercial signage of the area, but Eisenmann’s building in particular hasn’t weathered well.
Disappointing though are the rear communal spaces. In OMA’s case there was clearly very little room available on the tight site, and the balcony arrangement makes the best of a bad situation.
The OMA block, main street elevation
…and the rear
Witterings on a second visit can be found here. Also here’s a locational model from the 2012 IBA exhibition, showing the block from the back:
The Eisenmann building does have some space round the back, but seems to have done little with it – compare this with the communal spaces of some of the other IBA buildings and it seems like a lost opportunity. Admittedly it has to suffer the messy rear access areas of shops at ground level, but even so… The design though is more complex than may be apparent to the casual observer – the floor plans are oriented to two different grids: that of Berlin’s 19th century extant street grid (i.e. the existing streets and blocks around it) but also the Mercator grid (i.e. the global orientation of east-west-north-south), apparently referring to the concept that the building existed both in its immediate context, but also tied West Berlin (as it was at the time) to the rest of the world as global location.
And the rear
A nod towards the residents’ facilities (a sandpit, basically) although the grid motif is carried through to small scale.
A bit of the wall
What is really interesting about the Eisenmann block is not (only) what was built, but what wasn’t. The original competition was for the entire block, retaining only a handful of existing buildings. Eisenmann proposed a complex series of off-set grids, forming a public garden, to create “a monumental and symbolic area […]” which would be “…sufficiently profound to excavate all its cultural meanings.” If this sounds a bit pompous, it should be borne in mind that at the time the site stood in the shadow of a still very real Berlin wall. I don’t know whether the fall of the wall killed the scheme, or some other factor. Interesting to compare this with Eisenmann’s now built Holocaust Memorial.
Shots of the model from the IBA exhibition a couple of years back – I tried to work this out, and I think that the block as built was not a segment of this, but actually was actually reworked using the same ideas into the corner site on the left, below, which in the model isn’t a match:
And also a shot from the larger location model, which interestingly has been divided into panels along street lines, but also has cut lines following the Mercator grid. The built block is located top right corner, the OMA block is across the road to the right:
