  • City Scale Overview The City is undertaking large scale regeneration. Many failing neighborhoods have been Our study is located in a suburban low density residential neighbourhood in Oak redesignated as eco corridors Park, Detroit. We have chosen Detroit as it exemplifies the typical American city suffering from providing localized urban declining fortunes of the car industry and empty abandoned streets caused by the sub prime mortgage agriculture and renewable energy. Neighbourhood crisis. With large areas of Detroit abandoned and left to decay its time to re-evaluate the fundamental structure of the city alongside recommendations for a new denser suburban grain to create a true resilient city. As a starting point we have asked ourselves the simplest of questions; can we turn these abandoned parts of the city to the advantage of all and instil a shift to localised urbanism and sustainable living post peak oil? In answer we believe we can – by giving back swathes of land within the city to urban agriculture, bio fuel crops and renewable energy resources such as solar farms. The subsequent reduced city area available for 2009 residential use enables the opportunity for the intensification and restructuring of the remaining suburban areas Block into local centres capable of supporting themselves from a social, environmental and economic standpoint. All this must be in keeping with the American Dream of freedom of choice. Opportunity for every person to choose how they want to live, whether to redevelop their plot of land on their own, or perhaps with a neighbor, or maybe a developer, or to keep the big house and all the land. Broad choice of accommodation is at the heart of our proposal to foster diverse social sustainability. It would be naïve to suggest successful regeneration by forcing everyone into high density apartments. Living We appreciate this brief submission is part of the starting point on a issue which needs much more research, trial and error, before a workable solution is found. Therefore this paper can only hint at a suggested direction in relatively simplistic terms with some broad assumptions made. 2029 The diagrams conceptually illustrate urban restructuring at the city scale over a twenty year period with some areas of failing industry and predominantly residential areas reallocated for Hi, I’m Tim and I’ve lived in food and energy production.

The location of the selected neighborhood is highlighted in red. Re-Urbia is going to help turn things round by reviving our neighborhoods. 020709-03-0020
  • There aren’t enough facilities City Scale Neighbourhood like shops and parks in our neighborhoods as there are too few people to support them.

  • Living The houses are pretty big, bigger in fact than others round here as City Scale they’re over two floors. That was a major factor in us deciding to move here, along with the garden, garage and community 20 Years time facilities in the courtyard. There’s a barbeque area, allotments and Existing a safe place for the kids to play and mix it with others their own age. It’s a great way of getting to know your neighbors! Example of future intensified bock illustrating potential mix of building typologies. Neighbourhood We’ve lived here for years and I’ve put a lot or work into the house so I don’t really want to move. I like the way this area has moved on though. You didn’t used be able to walk to the shops which are great because I don’t like drive too much anymore. Block Living I love knowing that I’m helping the environment by living as sustainably as possible. I grow a lot of my vegetables, I don’t have to drive everywhere and we produce a lot of our own energy. We had a house on a huge plot which was far too much land for us to maintain. The new government policy and incentives to subdivide our property was perfect for us as our house was pretty old and in disrepair. We built two houses and we rent one out and live in the other It’s our first time buying. We really wanted to get a place which is great for our finances. in the city center but couldn’t afford the prices. This is the next best thing though as there are shops, bars and cafes with everything we need. The transport is really good into the city so we don’t need to worry about saving for a car right away, if at all. 020709-03-0020
  • Agricultural and green walls are of using space that otherwise wouldn’t be used. There is more than a 1 to 1 ratio of green area versus building floor space. We can grow a lot of our own vegetable in the communal allotments within the block. We set up a rota for day to day tasks. 020709-03-0020
  • City Scale The new block is built around the idea of shared communal gardens where everyone can get to know each other in a safe environment. There’s a barbeque area, space for kids to play, vegetable allotments and a sustainable urban drainage Neighbourhood system which we can use to water the landscape and vegetables. Those who have electric or hybrid cars can even charge up from the solar array shading the parking spaces. Block Living 020709-03-0020
