In context with the story
New construction of the parish centre "Johanneshaus" in Neu-Ulm, after the previous building had to be demolished due to various construction defects.

The bar was high!.
The new Johanneshaus was to be rebuilt on the old site, i.e. in the immediate vicinity of the city-parish church of St. Johann-Baptist, one of the world's most important expressionist church buildings of the 20th century. Built in 1857 as a French garrison church, this building was architecturally brought into its present form between 1922 and 1926 and then again after the Second World War by Dominikus Böhm (1880 – 1955).

"It quickly became clear," said the architects led by Wolfgang Heisler, Freie Architekten in Ulm/Donau, "that we wanted to develop a very restrained building, a building with a quiet façade facing the church - a building that borders Johannesplatz at this point."

Making congregational life tangible.
The clearly geometrically structured perforated façade - high rectangular windows on the upper floors and double-leaf doors on the ground floor - and the deep reveals (24 cm concrete, 28 cm thermal insulation, 4 cm air layer, 9 cm clinker shell) structure the building without taking away any of its restrained elegance. With this square façade and the concisely steep gable roof, the new building fits unmistakably and at the same time harmoniously into the challenging urban planning situation. The reference to the Church of St. John the Baptist opposite, which had been built with the Jura limestone of the demolished Ulm fortifications, among other things, was taken up again with the appropriate choice of material and colour. The open perforated façades, which are reminiscent of Oswald Mathias Ungers' "New Clarity", transport a lot of light into the interior and create views in all directions with reference to nature. The house opens onto the square on the ground floor via large double-leaf doors and gives an insight into the life of the community - in the hall, in the foyer - and on the other hand, looks from the inside to the outside, over the courtyard to the southwest to the kindergarten. In this way, parish life became comprehensible and visible and should – and this is the aim – also enliven the square between the church and the Johanneshaus in the future.

Unobtrusively perfect technique
The light-coloured material of the outer shell, a clinker brick in the colour of Jurassic limestone, in a slender bar format with a depth of 90 mm, a height of only 40 mm and different lengths between 190 and 390 mm, a KHlz 1.6/28, has been bricked up here as a foot assortment and thus conveys the deliberately restrained simplicity through its texture. This stone, with the factory designation »passo FK«, was manufactured by GIMA, Girnghuber GmbH in Marklkofen. Structurally required solid clinker bricks and pre-notched bricks complemented the delivery.

The entrance area and also the southwest-facing bay window at the community hall are clad with large-format, red Eternit panels to functionally highlight these components.
Finally, it should be mentioned that the entire new building of the Johanneshaus was built completely in passive house construction. In addition to the already mentioned, highly thermally insulated three-shell wall structure, the Construction of the floor on the ground floor (viewed from top to bottom: 20 mm parquet, screed, 20 cm insulation, the floor slab and then another 10 cm of insulation underneath), the triple glazing and a controlled ventilation system in accordance with the passive house standard as an important contribution to saving energy and conserving resources. In addition, the building was developed to be completely barrier-free. [...]
