3.2 BUILDING USE According to the survey conducted in Tangting , the settlement exhibits a balanced and diverse distribution of building uses, with residential buildings dominating at 67%, followed by commercial structures such as restaurants, shops, and homestays at 8%, which contribute significantly to local economic activity. Institutional buildings, including schools and hospitals, account for 5%, providing essential medical and educational services, while 5% of buildings are vacant, reflecting out-migration as residents seek better opportunities elsewhere. Additionally, 6% of buildings are mixed-use, combining residential and homestay functions, 7% are social buildings like ward offices and community spaces, and 2% are religious buildings. This distribution highlights the settlement's multifunctional character, where residential needs are balanced with commercial, institutional, and social infrastructure, fostering a vibrant and self-sustaining community. In contrast, Cluster D presents a markedly different pattern, with a heavy emphasis on residential use. Here, 79% of buildings are residential, indicating that the cluster is primarily a residential zone. Mixed-use buildings make up 17%, suggesting that some households have adapted their homes to include homestay functions, likely in response to the growing tourism industry. However, Cluster D lacks commercial, vacant, and religious buildings entirely, and institutional and social buildings are scarce, accounting for only 1% and 3%, respectively. This limited functional diversity suggests that Cluster D is less economically active and lacks essential services compared to the broader settlement. Residents may need to travel to other parts of Tangting for access to schools, healthcare, shopping, or community activities, which could pose challenges, particularly for elderly residents or those without reliable transportation. The absence of vacant buildings also indicates that out-migration may be less prevalent in this cluster, or that vacant properties have been repurposed. The disparity between the overall settlement and Cluster D underscores the need for targeted development in the latter to enhance its functional diversity. While Cluster D's strong residential character offers a quiet and authentic living environment, the lack of commercial, institutional, and social infrastructure limits its potential as a self-sustaining community. Addressing these gaps, particularly by increasing access to essential services and creating spaces for economic and social activities, could improve the quality of life for residents and contribute to the overall development of the cluster. Furthermore, the higher proportion of mixed-use buildings in Cluster D highlights its potential to cater to tourists, but the absence of commercial and religious structures may limit its appeal.
