Feeling blue: Is there a market for urban houses? Yes, according to Crest Nicholson, which sold the first eight houses released at Park Central in Birmingham within days. The housebuilder will be developing 200 houses as part of the 1400-unit scheme, designed by Gardner Stewart Architects. The scheme to transform the former Attwood Green estate is being carried out by Crest Nicholson in partnership with Birmingham council and housing association Optima Community.
