Group 1 - The concept of a "good house" is defined by five key elements: good standards, good design, good materials, good construction, and good maintenance. Good design is emphasized as a crucial prerequisite for building a good house, focusing on meeting the specific needs of users [1] - The recent national "good house" design competition selected 83 award-winning designs from nearly 2000 submissions. The application of these designs in housing projects is expected to significantly enhance the quality of living for the public [1] - Good design can cater to the differentiated needs of three generations living together, providing spaces that are functional and comfortable for children, middle-aged individuals, and the elderly, thus creating independent yet interconnected living environments [1] Group 2 - Award-winning designs have integrated service spaces such as stairs, elevators, and plumbing into centralized areas, allowing for greater flexibility in the layout of living spaces. This separation of structural elements from service lines enhances the potential for personalized designs [2] - Good design is applicable not only to new constructions but also to the renovation of old houses. Strategies like pipeline separation and modular renovations can improve the performance of aging residences, thereby increasing residents' willingness to update their homes [2] - The design guidelines released by Ningbo City in Zhejiang Province provide various renovation scenarios, including home office, elderly care, and child-friendly designs, detailing key renovation aspects and implementation checklists to meet diverse needs [2] Group 3 - Good design should adhere to principles of usability, economy, sustainability, and aesthetics. Designers are encouraged to be creative in concepts, innovative in material technology, and inventive in spatial usage, thereby promoting the overall construction of good houses [3]
