Its origins as a camp for convict timber loggers led to the realisation of the extremely fertile soil and potential for agricultural prosperity.

[1] In 1860 Grossmann and Brough house were constructed opposite St Mary's the Virgin Anglican Church, near the railway and away from the threat of flood.

The idea was not to replicate roses entirely from the 1870s when Grossmann House was (newly) built, but rather to select heritage species (cultivars) which would give recurrent flowering over a long period.

[3][1] In 1986, the street-front verandahs to the house were restored and basic kitchen and bathroom facilities were introduced to serve a caretaker.

A NSW Government grant enabled painting of the exteriors of Brough and Grossmann Houses in matching colours, another step towards linking the mirror-image properties as conceived over 140 years ago.

The strong business partnership between the two merchants, Owen and Beckett, is reflected in the construction of their identical two storey Victorian houses next door to each other.

Based on a centre hall plan the front entrances become side doors and the length of the house extends along Church Street, thereby optimising the verandah and views.

Original internal joinery is cedar and this, along with other interior finishes (plaster, tiles, timber flooring) are presented with little embellishment.

[1] The gardens were generous in size and, perhaps predictably, given the symmetry of Owen and Beckett's arrangement, the laundry building is situated on the centre line of the properties.

This simple, rectilinear structure has a central partition, dividing the area thus providing each resident with semi-private facilities.

The historical associations of these two buildings make them of great interest in their relationship to the original owners and later use as part of the Maitland Girls' High School.

Historically the house reflect Maitland's nineteenth century prosperity and significance, especially in its location on the axis between the railway station and High streets.

[1] The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales.

Grossmann House forms an integral part of an historic nineteenth century townscape dominated by St Mary's Church, large fig trees, residences and gardens.

Grossman House serves as a museum of early Maitland urban life and relates well to the other nineteenth century buildings nearby.

Grossmann House is a rare intact Victorian townhouse providing an accurate representation and presentation of the eighteenth century through its furnishings and architecture.
