FORA and Beth Hughes, with Raul Moura and Tudor Vasiliu, have been selected as one of four finalists for the second phase of the Danish site in the Nordic Built Challenge - an open multidisciplinary design competition for the refurbishment of five buildings one in each Nordic country. Their proposal addresses the Ellebo Housing Estate in Ballerup, Denmark. The estate was built in 1963, and features four buildings for a total size of 20,000m2, enclosing playgrounds, playing fields and green recreational areas. Their challenge was to renovate the existing buildings and outdoor areas, and for 5,000m2 of additional housing. More images and architects' description after the break.
