Green8 by Agnieszka Preibisz
and Peter Sandhaus


Architects Agnieszka Preibisz and Peter Sandhaus have unveiled a conceptual skyscraper for Berlin with a twisted figure-of-eight structure that curves around elevated gardens and is held up by cables.

Agnieszka Preibisz and Peter Sandhaus, who are both based in Berlin, developed the design to contribute to a new masterplan being put together for the eastern quarter of the city.

"The state of society in the twenty-first century requires that we develop new visions for living in densely populated inner cities," Preibisz told Dezeen. "This process inherently triggers an essential confrontation of material and social values, and so there is a nascent yearning for an architecture that offers a high degree of potential for community."

Describing the building as a "vertical garden city", the architects have planned a network of gardens and greenhouses that would slot into the two hollows of the figure-of-eight, intended to serve a growing desire among city dwellers for self-sustaining gardening.

Residences would be arranged to encourage neighbours to interact with one another, fostering a sense of community that the architects compare to social networks.

"While in social networking, the border between the public and the private spheres is being renegotiated, architecture and urban planning of cities such as Berlin lags behind these significant social and demographic changes," they explain.

Named Green8, the tower is designed for a site on Alexanderplatz. The architects are now consulting with an engineering office to assess the viability of the structure.

Here's a project description from the architects:

Green8 Concept

How Do We Want To Live?

While trying to answer the query of how and where to house, many modern families today are torn between the desire for a pulsating urban life and the craving for a lifestyle in harmony with nature.

Our identification with and our desire for a free and urban life style defined by short distances to work, excellent public transportation, and proximity to cultural and commercial amenities, does not need to end with the decision to start a family or with retirement from active professional life.

Current trends towards a 'sharing-spirit' and a new participation in the community life counteract the anonymity and isolation in the metropolis. While in social networking, the border between the public and the private spheres is being renegotiated, architecture and urban planning of cities such as Berlin lags behind these significant social and demographic changes.

The unease with the global imperative of continued growth propagated by financial markets, seems to be spreading. Confidence in industrial food production finds itself nowadays significantly eroded. At the same time also the mass production of organic and healthier food has its limits and fails to appease growing groups of customers.

The longing for self-sustaining gardening and for knowing about the origins of what one is eating, are the most important reasons for the current boom in urban gardening.

What do these developments mean for architecture and urban planning? How do we want to live and house in the future?

As an integrative solution to this dilemma, the architects Agnieszka Preibisz and Peter Sandhaus are proposing project Green8 for a vertical garden city on Alexanderplatz in Berlin.

The residential high-rise structure is based on a business model of a cooperative collective. It envisions a self-determined community encompassing all generations. With its generous greenhouse and community spaces Green8 offers to organise not only the food production but also the sport and leisure activities, as well as the care of children and seniors.

Green8 reflects a dream come true: living in the centre of the city with breathtaking panorama views, while having one's own vegetable garden at one's doorstep.

Thanks to its cooperative and integrative principles, this housing concept is economically efficient. This form of home ownership is free from many constraints of real estate or land speculation, and the long term costs are lower than those of conventional homes.

Green8 is not a house. It is a life form.

    The section looks like a dollar sign and probably for a reason.

      Cynical for the sake of being cynical? I think it’s a lovely design.

      • chao

        Agree with Chris!

    • jsk

      Y€$ ! ;)

  • These people know how to render parrots instead of pigeons. Such a creative bunch. Duh…

    Ribbed – for her pleasure.

    Without floor plans and diagrams of how the garden and greenery works, all these Green concepts are related only to colour and have nothing to do with sustainability. At the moment it just looks like a big vertical greenhouse with extremely high costs for the structure.

    Please stop this hysteria. If you want to be forward looking, please study the subject and not just the formal shapes.

    Implying a glass tower can be sustainable…
    Pro tip: a glass tower can never be sustainable.

    Tropical parrots in the middle of Berlin. Creativity at its worst.

    • michael

      Dude, amsterdam is full of parrots so why not Berlin?

    • Jeremy Hernalesteen

      Actually Brussels is invaded by green parrots. I mean it literally – I am not calling MEP or green lobbyists parrots but talking about Rose-ringed Parakeet (Psittacula krameri).

      However I see your point

    • Siobhan

      The parrots are the best bit!

    • disqus_CTcMDqCKkR

      Renderings aren’t real bro.

    “Lets stick the elderly care floor at the top of the skyscraper.”

  • Rae Claire

    When algae start colonizing the glass it really will be a “greenhouse”. Parrot poop, anyone?

    • chloe

      The greenhouse facade is ETFE Teflon-like membrane cushions or something. Not glass, if I am not mistaken? So neither algae nor poo would stick to it.

    The dream of the 00s is alive in Berlin.

  • Claudia

    Did anybody actually R E A D what this project is about?

    At the 2005 World Summit on Social Development it was noted that sustainability requires the reconciliation of Environmental, Social Equity and Economic Demands – the “three pillars” of sustainability.

    I am not a designer but the way I think of it, this vision has something to offer in all these 3 fields.

    Plus, IMHO, it looks pretty good.

    • christin

      Looks too good for Berlin. Sadly something cool like this will probably never be built in this city. Not in my lifetime.

  • faan

    Looks like a cobra coming out of ground.

  • freddy

    Having my vegetable garden and a shared greenhouse right in the city centre would be great! It’s better than a two hour drive and in the long run more sustainable.

    I would agree on the cost. Even with this co-operative financing of community housing thing they have going on in Germany, it would still be for families with money.

    Shape-wise I personally prefer the minimal and the simple but here, with the organic gardening and all, the bio-morphology actually makes sense to me.

    Just awful.

  • a-ngine

    More cheesy would be a fondue.

  • This process inherently triggers a confrontation between jibber and jabber.

      Give it a try and be less idle.
