Berlin is a inexperienced metropolis, with the Tiergarten at its coronary heart and a necklace of forests and lakes. Nonetheless, a public park atop a brand new workplace constructing is a brand new mannequin of city landscaping for the German capital. Named Darwinstrasse 1 for its road tackle within the Charlottenberg district, that is an eight-storey linear block – the primary to be constructed on a former industrial web site beside the River Spree.
Designed by the prolific Berlin agency Grüntuch Ernst Architeken, it applies the sustainable structure ideas specified by Hortitecture, a guide that features contributions made by 33 architects at a collection of symposia on the synergy of structure and plantings, and the way that enhances the surroundings.
Uncover Darwinstrasse, an elevated, new Berlin park
As GEA observes in its introduction, ‘not like strong constructing supplies, that are mounted and managed by the architect, residing inexperienced supplies problem the design with the dynamics of development’. It’s a problem GEA has mastered in a number of different business initiatives and colleges, and in Berlin’s Wilmina Lodge, which the agency created inside a former girls’s jail.
The fee for Darwinstrasse 1 got here from Bauwens Growth, a Cologne-based agency, who responded enthusiastically to the planners’ mandate for a publicly accessible roof backyard that might create a invaluable amenity for tenants and the neighbourhood. An open staircase runs up the west aspect of the 120m-long block to the north finish of the fourth flooring and the two,200 sq m park cascades down from the south finish. Timber in planters 2m deep rise from every terrace.
Ingenhoven Architeken’s Marina One advanced employs an analogous technique in Singapore, the place each new business growth has to dedicate 25 per cent of the location to inexperienced area that’s open to the general public 24/7. In Berlin, the place innovation is usually stifled by a forest of rules, it’s a new departure that deserves to be extensively copied, simply because the Viaduc des Arts in Paris and New York’s Excessive Line have impressed planners around the globe.
Inevitably, the park and staircase added to the complexity and price of development. ‘We have been fortunate to have a consumer keen to pay for that,’ says GEA co-principal Armand Grüntuch.
For the architects, a significant problem was to bolster the roofs to maintain the burden of moist earth 40-150cm deep and create a water-resistant seal. They specified a concrete with embedded carbon and the constructing utilises renewable power from the neighbouring energy station. The open-plan flooring are lit from expansive home windows that may be shaded by exterior blinds. The areas have an open technical infrastructure within the ceilings and they are often simply reconfigured with soundproofed partitions to accommodate a thousand workstations.
A big Bavarian funding agency purchased Darwinstrasse 1 and is now leasing it to different corporations. The landscaping will proceed to develop however already it has created a major micro-climate, with a measurable distinction of temperature between park and road. Multiply that ten thousand instances and Berlin could be the greenest metropolis in Europe.
