Interior Space and Exhibition Design Hilltop House Residential by Chun Tang Hilltop House is a residential interior design for a single family home of 1300 square meters. The house stands on a mountain top, above a large wetland park. Three generations live in the home, so the colours, forms and functions of each area were planned for ages from under one year to over eighty years. The exterior walls facing the mountain were replaced with large glass panels on every floor. A 60 meter corridor with floor to ceiling glass surrounds the lower level. Chinese cultural elements, such as curved lines and bamboo shapes, guide the decoration.
