and completeness in presentation. The house represents the evolution of
Baldwinson's thinking beyond his earlier European influenced designs into a more site-responsive, locally adapted Modernism. Demonstrating an innovative approach to the incorporation of outdoor spaces, sensitive to the environment and place, it is a benchmark house for the manner in which the interior and exterior is integrated - a theme developed by followers throughout the 1960s. Simpson-Lee House I Wahroonga is highly regarded as an outstanding work of architecture by the architectural profession, a house which was aesthetically distinctive for its time and now exemplifies a style. Glenn Murcutt has written: 'Spatially, the house is an excellent example of a work holding to the principles of the "Modern Movement" in architecture and an exemplar of Arthur Baldwinson's architectural contribution to this country. The house sits so quietly and it is entirely unpretentious.'

As a consequence of the single continuous occupation and ownership since 1958, the house is in its original condition. It has been carefully maintained, without structural changes or changes to finishes, - and beautiful, it is! The house is modest in size, reflecting the Modernist ethic of modest housing standards of the time. Furthermore, the house is representative of Baldwinson's mature work. It is an exceptionally good example of early 1960s modern architecture in Australia. The house is in very good condition and has "aged" beautifully over the forty odd years since construction.
