The house and two of the lots were sold to Mr and Mrs Phillip Jones who undertook urgent and major conservation work.

It is a large rectangular house, drawing in plan from the compact form of the late 18th and early 19th century English neo-classical villas, with well proportioned rooms arranged around a central square hall containing a geometric staircase describing a circular wall beneath a hemispherical dome.

In the late 1850s most of the unfinished detailing was made good in a simple manner with mitered, moulded architraves instead of the elaborate aedicular forms of the original work.

The house retains in its wallpapers and paint finished, together with its services (bells, water closet and ballroom) remarkable evidence of both building, the effect of the financial depression and the taste of its builders.

It commands extensive pastoral views and is a dramatic European monument set in isolation in an Antipodean landscape.

The configuration of its fabric, largely in its c. 1860 form, is patent physical evidence of the high expectations of colonial settlers of the 1830s and early 1840s and the severity of the economic crash of the 1840s.

It is the earliest known surviving example in Australia of a house design generated in part by considerations of an integrated sanitary plumbing system.

It is an exemplary example of the 19th century builder's art embodied in the quality of the stonework, brickwork, timber selection, carpentry and joinery, plasterwork, hardware etc.
