The concept of estimating usable floor area of buildings based on cadastral data

Abstract

Usable oor area is one of the most important spatial attributes of buildings and premises. It is used, for example, to determine the basis for their taxation. Unfortunately, the question of proper determination of usable oor area in Poland has remained problematic for many years, which is closely related to the occurrence of various de nitions of usable oor area in the currently binding legal acts. Consequently, usable oor area is not a universal attribute. This means that in certain cases signi cant discrepancies may occur between the usable oor area of the same structure, determined for di erent purposes. In addition, despite attempts made to unify the principles for the performance of surveys of building structures and their parts, this requirement still can not be recognized as fully met. Therefore, there is no doubt that the problem of reliability and availability of data de ning the usable oor area of buildings is becoming even more important in view of the introduction of the 'ad valorem' tax, which has been planned for years. For this reason, this paper proposes a universal, multi-variant method of estimating usable oor area based on geometric and descriptive data of buildings contained in the cadastre. The Authors, taking into account the applicable legal regulations, have considered the possibilities of practical implementation of individual variants of this speci c method. They have carried out empirical tests of e ectiveness of the proposed approach. They have also de ned tasks for which this method of determining the usable oor area of buildings would be particularly useful.

Estimation of Usable Area of Flat-Roof Residential Buildings Using Topographic Data with Machine Learning Methods

“…PVR also plays a significant role in the real estate management, spatial policy, sustainable development policy, and tax system [8][9][10][11][12][13][14][15][16][17][18]. PVR data have become a subject of abundant research indicating its incompleteness or low quality [5,[19][20][21][22]. The real estate appraisal largely consists of estimating the property's value based on the transaction prices of similar buildings.…”

“…Ultimately, both standards are currently 'withdrawn' by the Polish Committee for Standardization, which has been recommending PN-ISO 9836:2015-12 [35] since 2015, but due to a lack of law amendments, the newest standard continues to be unused. The only approach of estimating the usable area of single-family houses that has already been developed and that is known to the authors is the method of Benduch and Hanus based on geometric and descriptive data of buildings contained in PVR [22]. In three variants, differing with a level of detail, Benduch and Hanus used existing geometric data of a building, number of overground and underground stories, information on the material used for the construction of external walls, and total number of chambers.…”
