At the end of the XX-th century the concept of development as a synonym of modernization and progress has been heavily criticized. It has been said that such an approach defines the development as a teleological, uniform, linear, normalizing and instrumental process. This critique, known as post-development approach includes various ideologies, e.g. conservative anti-modernism, neo-liberal rejection of state`s interventionism, and cultural relativism. The author claims that the main weaknesses of development concept are due to the unjustified generalizations with respect to the subject, time and space in which the processes are observed. Coping with those weaknesses do not necessarily require taking radical post-modernistic positions, rejecting any valuation of regional patterns of development. Regional studies may treat development as an open process, not necessarily leading to predetermined outcomes, and not always following the paths of the developed regions. There are development paths that are nonlinear processes in which the crucial role is played by the endogenous factors, such as activity of local actors.
If architectural heritage in cities is recognisable for the masses, it does not raise doubts as to its value. However, if the architecture is controversial, relatively young, or can be associated with a problematic legacy and difficult past, its valuation raises ambiguities. Unconventional valuation methods can help resolve these uncertainties, making it easier for local decision-makers to make sounder decisions. This paper presents a proposal for valuing Warsaw’s modernist WKD Ochota train station, using a combination of cost-benefit analysis and a Delphi panel. The study carried out for the purposes of this article revealed that such architecture, although ambiguous, is treated by the local community as valuable not only in economic terms, but also in social and cultural terms.
