[The quality of life in historical urban sections--basic principles for urban renewal planning].

Living in the city is increasingly en vogue. In particular, ancient historical town areas are redeveloped to residential areas with the aim of creating "Isles of the Blest" while engendering a host of new problems; unhealthy additional density by building on originally free inside sites of blocks; new garages for residents right in the middle of redevelopment areas resulting in traffic nuisance due to congestion, noise and exhaust gases in narrow alleys; and hence, unhealthy living. Healthy living demands restoration of the original qualities of the historical town districts as a condition sine qua non for all town planning operations.
