As a result, the historic centres of towns and cities are deteriorating, while their suburbs are spreading. One of the main problems affecting the rehabilitation of residential buildings is that it is extremely difficult to accurately estimate the costs involved. Although there are established methods (and technical documents available) to aid the costing of new buildings, there is a lack of official information about the costs of rehabilitation work, particularly as regards the external envelope of buildings. This article demonstrates how to determine rehabilitation costs (with particular emphasis on the envelope of residential buildings) by gathering information from specialized companies, assessing price variability and consulting databases of rehabilitation costs from other countries. It also presents some examples of costing for particular rehabilitation jobs.展开更多
