Common choices for residential buildings in China include glass, aluminum, steel, wood, and ceramic tiles, all of which can be used to create contemporary, sleek, and attractive designs. Glass facades, for instance, are becoming more popular in high-rise residential buildings as they allow natural light to enter the home and provide panoramic views of the surrounding cityscape.
d) Cost Considerations
Building material costs play a significant role in the overall budget of residential projects. While high-quality materials may offer long-term benefits in terms of durability and performance, they may also increase initial construction costs. Therefore, developers must strike a balance between quality, aesthetics, and affordability when choosing materials for residential buildings.
In China, developers are often faced with the challenge of keeping construction costs low while still adhering to modern design and performance standards. As a result, many developers use a combination of cost-effective materials such as concrete and steel alongside more expensive finishes, such as wood and stone, to achieve a balance between affordability and quality.
