the deck space. The sleeping level above contains two bedrooms, a study and bathroom. This level extends from the southern end of the lower level spaces and cantilevers over the deck.

Thurlow House was described in Seidler's first promotional book, Houses, Interiors and Projects, which was published in 1954. It remains relevant because of the high level of integrity that the house has retained: The structure of the house consists of brick/stone cavity walls, steel columns and beams, timber-framed floors and roof. External walls are constructed out of randomly coursed sandstone and pale "Chromatex" bricks manufactured by Punchbowl Brick and Pipe Co. while internal walls are constructed out of timber stud framing. Floors are constructed with oregon joists fixed to lugs welded onto steel beams. Floors and internal walls are lined with tongue and groove tallow wood boards. The roof was originally lined with 4-ply asbestos felt (a commonly used building material at this time) with white marble chip protective finish, insulated with aluminium sarking and Insulwool batts and flashed with copper. It has since been replaced by metal decking. Windows are framed in steel. Internal lighting was quite advanced for the period and still remains in place – recessed ceiling mounted down lights and fluorescent tubes in the kitchen, above the east wall of the living room and dining rooms. Fluorescent tubes are also located in a recess behind the built-in cabinet mounted on the north wall of the living room. Supplementary wall mounted fixtures augment the main lighting. The kitchen was originally comprehensively detailed and equipped to a standard above most houses of the period. Much of this remains, such as an exhaust fan, cupboard and servery joinery and fitments. The kitchen is linked to the main bedroom by a dumb waiter. Condition , the house was in relatively good condition, although in need of some maintenance. The landscape setting is overgrown and weed-infested.

The original roofing has been replaced with metal decking, possibly
