Greening up was initially frowned on in the Bauhaus era of "modern building" as of 1920 because it reflected the older "garden city" style. Bauhaus was all about clearing off the useless affectations on buildings. Minimalism. The new ideal was the facade which was clean and edgy without a lot of detail." A live-in machine." It often struck people as cold, clinical, and soul less. Since then, things have relaxed a bit and greened up walls are no longer taboo as they once were in the Bauhaus era. A rejection of extreme minimalism took place and natural, warm, full greening was once again "allowed".
The few original houses from the Bauhaus time of approx. 1935 are under the strict protection of the government; the historical monuments preservation dept. They are usually painted only white because this was the typical color of the"Modern building era". The houses seem bright and pure, from afar, but shrill and glaring up close. Greening up is virtually ruled out here even if they would soothe the blinding effect of the facades. Only the original is the motto. After all, it could be possible to put simple pail plants in front of the walls. Self-clinging climbers and also strong vigorous plants are to be avoided for houses from later time periods.
With greening up in the context of 'new buildings,' plants are preferred which do not grow 'wildly', but need assistance from the cables and wires to form and grow as one desires. It is recommended to promptly discuss beforehand your greening wishes with the architect because it can then be arranged in the stylistic form of 'his' building. The attachment of the cable system may be demanding if Special façades or different façades need to be greened.
After approx. 1950 ideas of "modern building"were also implemented for municipal housing units. Building greening didn't play a role here at first, but in the course of the environmental movement the first attempts were made around 1980. To safeguard rental quotas, these buildings were redeveloped and rennovated en masse and also greened up starting around 1990, particularly the windowless gables. Unfortunately, afterward these facades were often expressionless, even after walls were brightly painted (walls with ETICS would not stand any dark colors). And unfortunately such large green ups were neglected from time to time because of lack of interest and care.
For the office and trade building construction, the omens had changed since 1920. "Building with greenery" increasingly begins to play a role. Facade gardens become an integral component of a high-quality architecture. Parking garages are greened, high growing walls are made and building green up in all facets is hard to ignore. Also completely new green up systems are tested directly on the facades, but are however still very care intensive.
A negative trend also begins to emerge now. It includes warehouses, car parking houses, boundry walls etc. More and more such commercial buildings are perceived as ugly and disruptive and required greening as a beautification measure.This originates from the positive knowledge that greening can also improve the image of large, boring, flat uniform areas. The dark side: A builder-owner developer must then no longer take the trouble that is necessary to create high-quality buildings. One could translate " modern buildings" with expressionless, cheap, dull facades. And greening is reduced to just the icing on the cake , to provide "architect comfort," provided that architecture is really deserving of the name.
