Should I stay or should I go?

You may be forgiven for thinking this idyllic setting is in Rio, in fact, this is Sheffield, welcome to the Park Hill estate in all its monolithic glory. It houses roughly 1000, and has been on the councils demolition agenda for sometime now. Deemed an eyesore, a blot on the countries landscape, a monstrosity, the estate has been the subject of much heated controversy, should it go or should it stay? How ethical is it to disregard the harnessed energy of 3 weeks full output of a power station, or filling 3 football stadia entirely with enough concrete to make to make the Barbican blush when the structure it self is as sound as the day it was laid? In many a councils eye, very ethical, as has been illustrated with estates such as the North Peckham estate and Robin hood Gardens, Poplar, Tower Hamlets, meeting an impromptu demise. 'Knock it down I say, displace hundreds of residents, disrupt and disperse communities the country over and demolish all'  is too often seen in many 'regeneration' projects so my hands go swiftly up to Urban Splash who are undertaking the bold move of revitalising Park Hill whilst retaining all of the original structure. Granted it will have a large commercial interest, two thirds whilst retaining a third for social housing, roughly 300 which given the ruthlessness usually exercised in projects such as this I say bravo. With this ratio of housing distribution in mind I want to point out the fact that this regeneration will combine the middles with the working, whereas typical social housing comprises dwellings for the primarily the working which has widely been attributed to their turbulence. Let me refer to Jane Jacobs in her book: The death and life of great American cities: " The district, and indeed as many of the internal parts as possible must serve more than one primary function, preferably more than two. These must ensure the presence of people who go outdoors on different schedules and are in the place for different purposes, but who use many facilities in common". What she's writing about here is essentially being attempted within the Park Hill estate, the creation of a  mixed tenure community which if successful could fully invigorate and provide a stimulating platform across social spheres facilitating a cohesion usually unlikely.
