Determination of appropriate design and standard construction price of small agricultural product buying-selling building in Thailand

Abstract

This research aimed to (1) study and explore the demand for design and pricing models of small-scale agricultural product buying-selling building; (2) establish guidelines for designing such buildings to align with the needs of the target groups; and (3) determine standardized construction costs corresponding to the proposed building designs. The study integrated theoretical concepts on architectural design and construction costs and utilized quantitative data collected from 110 farmers in Chanthaburi Province and qualitative data from at least 18 key informants, including experts, academics, construction business operators, and government officials, selected through purposive sampling. The research instruments comprised (1) a structured quantitative questionnaire and (2) in-depth interviews. Quantitative data were analyzed using statistical software, while qualitative data were examined through descriptive analysis. The findings revealed that: (1) the design and pricing requirements encompassed key elements such as usable area, column structure, flooring, wall characteristics, roof structure, cost per square meter, and restroom design, all of which show consistent demand trends; (2) farmers' perspectives indicated that architectural design, financial investment, economic returns, and functional aspects are critical factors influencing demand at the highest level. Based on this study, the appropriate design and standardized construction cost for Thailand's small-scale agricultural product buying-selling building should prioritize farmers' practical needs and functionality, cost-effectiveness, and long-term value. Furthermore, compliance with relevant regulations and industry standards is essential to enhance the buildings' efficiency and sustainability.
