Buildings complete their formations within a set of parameters while being constructed. Buildings are formed with ground floor area, horizontal distances, static, reinforced concrete or steel projects, and electrical and mechanical projects. The parcel emerges as the first stage in the formation of buildings. The building boundaries of the building are determined in line with the structural form feature of the parcels, height ratios, and comparable construction rates. Building information modeling (BIM) is the process of creating a model network by entering the data analysis of each stage from the beginning to the end, from planning to completion. In the study, it was tried to find the answer to the questions of which process a building can be formed on its parcel, what should be considered, and how to understand it in the simplest way by entering the steps gradually in line with the criteria of this correlation between the building and the parcel.

As an expression of the informal economy, the night market is not only a place that could attract locals to buy goods but also a place where tourists can experience the local characteristics. While the night market brought economic vitality to the city's economy, it also brought some issues. A comprehensive literature review of night markets revealed that existing studies paid less attention to outdoor night markets' spatial operations and waste management. Grounded in the connection between sustainability and night markets, the present study reflected on existing research findings by adopting different periods of fieldwork to conduct a case study of the night market in Jalan 17/1A, Selangor, Malaysia. The study focused on three aspects of night markets: spatial operations, waste, and waste recycling. It found that night market operations brought localized regional economic benefits while causing more severe pollution issues, significantly affecting the region's environmental health and sustainable development. The findings revealed that local government regulation of night market businesses in Malaysia is weak (the issuance of business licenses is informed of the operational guidelines), and there is also no relevant monitoring and penalties by the local government to intervene in the misbehavior of night market consumers. Based on the results of the field survey and combined with the concept of sustainable development, the present study recommended suggestions for the future spatial operation and waste management of night markets. Innovative and novel perspectives of the study combined qualitative observations and data analysis to comprehensively examine how spatial considerations and waste management strategies intersect in the unique context of night markets—aiming to fill the gaps in the sustainability of night market operations and to protect the ecology of the surrounding territorial environment, contributing to the discourse on sustainable development.
