TOWN HALL
IN KORBACH
With the new town-hall extension in Korbach, agn –
heimspielarchitekten materially and non-materially em-
phasize the not quite new evidence that the world is
round and everything is or should be subject to a natural
cycle. On a large as well as on a small scale, as regards
urban development as well as construction, the line of
history is taken up and continued into the future.
A spects of further developed sustainability had already been ancho-
red in the competition organized in 2017 and announced Europe-
wide with, in the end, 133 participants. As a district-specific urban-re-
Grundriss Untergeschoss • Basement floor plan pair project, the centre of Korbach from 1377 and its historically charac-
terized surroundings was to be newly designed. For this purpose, the
town-hall extension from the 1970s had to give way but was allowed to
pass on to the coming generations its “genes” as heritage material in
the form of recycled concrete and bricks. A total of 5.823 tons of the
overall 9.617 tons of resulting from the demolition were thus entered
into the cycle of materials and given a new use in the supporting struc-
Bildunterschrift • englisch ture, the façade, the excavation pit and the planum. With this principle
of “urban mining”, all the materials in a new building are joined in such
a way, as it were, that they can be recycled and reused as single-origin
for future generations. That the broken brick from the extension in the
1970s can be rediscovered as granulation in the façade panels as well
as in the outdoor covering gives the public building an identity-establis-
hing, when it comes to the building history, even a reconciliating cha-
racter. The Korbach town hall becomes an exemplary model project in
Grundriss Erdgeschoss • Ground floor plan a sector where in Germany alone every year 544 million tons of mineral
raw materials are demolished and used for the production of building
materials. At the same time, rubble from the building sector to the
amount of approximately 231 million tons produces about 55 percent of
the waste. Fascinating about this project, however, is not only the su-
stainable and verifiable gain for future generations and the conserva-
tion of primary resources but also the design impact of the ensemble.
The clear combination of material and construction volume produces a
sensory accessibility and visibility for the urban society. With the urban-
development implementation, the architects show respect of the old
town hall and the neighbourhood and also produce a passage which
naturally and in a democratic sense leads into the interior of the buil-
ding. In this way, the public authorities also deliver a political message
Grundriss Obergeschoss • Upper floor plan – in a clear language: The world is round but the resources are finite.
