who has had a long association with the Seidlers, has further reflected that "I may have to a small degree helped introduce Harry Seidler to a new consideration of landscape and its relationship to buildings and in particular to his house. The simple play for instance, of shadowed leaf patterns dancing on crisply defined facades, gained his attention and raised the image of landscape as a dynamic participant." Penelope Seidler, nee Evatt Penelope Alice Marjorie Seidler (née Evatt) BArch, BBus, FRAIA, ASA was born in 1938. An architect and Seidler's professional partner, Penelope Seidler is the daughter of the Hon. Clive Raleigh Evatt QC (b.1900 d.1984); a prominent NSW Labor politician, Member for Hurstville 1939–1959, and his wife Marjorie Hanna Evatt (née Andreas), (b.1903 d.1984). The Hon. Clive Raleigh Evatt QC, the younger brother of the famous Labor Party leader and international jurist, Herbert Vere Evatt (also known as H. V. Evatt or Doc Evatt) was representative of a new generation of non-union, liberally minded men who stressed the need for the Labor Party to appeal to a broad electorate.

Several years later Seidler would marry Penelope Evatt on 15 December 1958. Harry Seidler has described his first visit to the Evatt family home at 69 Junction Road, Wahroonga, in 1950 as "momentous" and cites the Hon. Clive Evatt's support as persuasive in his decision to remain and work in Australia. The Evatt family home, now known as Parklands, is also listed on the State Heritage Register. The marriage to Penelope Evatt provided an entree into Australian political life. The pair attracted a good deal of publicity epitomising the up-to-the-minute modern couple.
