television "Harry Seidler: A Life" Seidler said of his home "I don't think I want to live anywhere else, ever - marvellous house. We love our environment and we've never changed anything, it is as exactly as it was. The only thing that might have changed is some of the artworks...But the house itself, I think will long outlast us." Harry Seidler resided at this house until his death at the age of 82, at home on 9 March 2006, after fifty seven years of practice as an architect in NSW. Harry Seidler was awarded the RAIA Gold Medal in 1977 the institute's highest honour, for outstanding achievement in architectural design and the promotion of architecture and the profession. The RAIA Citation states: Bruce Mackenzie, landscape architect Bruce Mackenzie was born in Sydney in 1932. He studied art at East Sydney Technical College before working in the graphic arts industry. He came to consider the study of landscape architecture his life's commitment and began working in the field in 1959. After ten years of landscape and design construction, though without formal training, he was admitted into the Australian Institute of Landscape Architects in 1969 and became National president in 1981. Bruce Mackenzie pioneered the use and conservation of indigenous Australian planting that made use of natural structural materials and native plants, combining a romantic attachment to landscape aesthetics with a pragmatic approach to conservation. He is considered one of the foremost practitioners of the 1970s and 1980s in the promotion of landscape design that respected and harmonized with natural environments. Significantly his first article extolling the use of native plants was published in "Architecture in Australia" in November 1966. In the late 1960s Mackenzie founded the firm Bruce Mackenzie and Associates. His office was located in Ridge Street, North Sydney, in a building housing client architects such as Harry Seidler, Bruce Rickard and Harry Howard. Bruce Mackenzie in reflecting on his involvement with the landscape design for Harry and Penelope Seidler House advised "they were early days in my career path and I would not want to add unwarranted emphasis on my contribution to the success of the building and its landscape setting. The main ingredients were already there in the form of remnant mature native trees and the landform of the small stream that the house overlooked. I merely reinforced these elements while the house itself stood proud." Mackenzie,
