The study "Frankfurt for Everybody" of AS+P Albert Speer + Partner GmbH includes the qualitative upgrading of housing estates of the 1950's to 1970's. As a first project of the city, the Heinrich Lübke housing estate of the ABG FRANKFURT HOLDING with circa 600 housing units is to become a model of sustainable renovation for larger, out-of-date housing estates.
In the urban planning / architectural realization competition AS+P's concept came out on top. The concept put particular worth on strengthening the qualities of the existing estates. The neighborhoods in the individual housing groups are to be upgraded through individually designed garden courtyards and newly-orientated accessibility. In many areas the urban structure will be aligned by new structures. The facades of the existing buildings will be opened up via an enlargement of the window surfaces and will receive heat insulation as well as a stony base floor. Loggias, which have been thermally exposed until now, are being integrated into the apartments and replaced by extended balconies. The modernization measures are supplemented by an overall energy and building concept which is supposed to reduce the CO2 emissions of the Heinrich Lübke Housing Estate by over 90 percent.
