An in-depth study of public housing in New York focuses almost exclusively upon the cost analysis aspect of decision. The costs of various construction techniques, design arrangements, and materials have been collected and analyzed. The stated aim of the report is to reduce cost as much as possible, with user comfort being a secondary consideration. In the light of this aim, basic plan designs are examined in terms of space and subsequent cost efficiency. The means for achieving the spatial arrangements recommended are examined from all aspects. Beginning with structure, comparisons are made between various systems. Interior elements, exterior elements, and mechanical equipment are similarly analyzed. Final recommendations are made for immediate solutions and long term considerations. An appendix contains indexes enabling the cost criteria to be extended to other areas. (RS)
