Four-generation house garden design refers to the architectural planning and landscape design of gardens for houses that accommodate four generations of a family. This design aims to cater to the diverse needs and preferences of elderly members, adults, and children, ensuring a comfortable and harmonious living environment. It often includes features such as multi-level outdoor spaces, accessibility for the elderly, and play areas for children. This type of design is gaining popularity in modern architecture, as it promotes family unity and social interaction.
