Spatial order refers to the perceived harmony, integrity, and completeness of the architectural heritage. Nevertheless, to the best of our knowledge, this concept has not been used yet to assess the heritage. This paper aims to demonstrate a multidimensional assessment of the architectural heritage value, in its urban environment, with the use of spatial order concept. We used field survey and statistical analysis to evaluate an example architectural heritage—Warsaw Ochota railway station in Poland—in four dimensions of spatial order such as architectural, esthetic, social, and functional. We found that the value of the heritage varies according to the spatial order dimensions and depends on the urban environment. Our findings could be useful for urban development policy, especially spatial planning. In particular, we postulate the need to focus on place-based approach to formulating policies for the protection and conservation of architectural heritage.
