Statement of significance:

No. 10 Thornleigh Avenue demonstrates the suburban development of the area following subdivision of formerly semi-rural land in 1914. The property retains the original allotments of the Thornleigh Estate subdivision. The substantial and attractive two storey Federation style house is remarkably intact. It is one of only a handful of two-storey Federation houses in the district, and it is a prominent and contributory feature in the streetscape.

Physical description: The house at no. 10 Thornleigh Street is a substantial two storey Federation style house which has been designed to address its two street frontages (Thornleigh Street and Patterson Street). A double height verandah wraps around the corner of the house. The timber verandah is set under the main roof of the house although the roof slope is reduced over the verandah. The main roof is hipped slate roof with gable roofs over the projecting bays on the Thornleigh Street and Patterson Street facades. (The verandah terminates at these bays.) The walls of the house are face brickwork with liver brick detailing. The projecting bays have large decorative bay windows at both levels, the first floor bay window having a different design to that of the ground floor. A bay window set at 45 degrees is located at the corner of the house set under the verandah. Other high quality features include very good leadlight and coloured glazing, oeil de bouef and Art Nouveau fretted and slatted timberwork. The house is set on a large block with a good garden and matching face brickwork front fence. Interiors are relatively intact.

Historical notes: The land on which the no. 10 Thornleigh Street is located was granted to William McDonald in 1859. The land was transferred to William Morrie in 1893 and then to James Bennett in 1913. Bennett subdivided the land in 1914 to create residential allotments as well as Thornleigh Avenue, Keppel Avenue, Bell Street and Sydney Street. The allotments were offered for sale as the Thornleigh Estate in 1914. A building covenant on the land title required new buildings to be constructed of brick or stone, roofs to be slate tile or shingles, and to have a minimum cost of 450 pounds.

Lots 10 and 11 of the Thornleigh Estate were sold to Ethel May Stevens, wife of Francis George Stevens, on 20 September 1915. Lots 8 and 9 (the adjoining allotments to the west) were purchased by Alfred Edwin Ellis on 27 March 1917 (together with allotments 4 to 7) and then sold to Ethel May Stevens on 13 September 1917.

A listing for the property first appears in the Sands Sydney Directory of 1921, indicating that the house was completed c.1920. The occupant is listed as Francis G Stevens. The delay in the completion of the house is likely to be due to WW1.

In 1952, the property, together with allotments 8 and 9, was sold to men who were in Holy Orders, being Redemptorists from the Novitiate and House of Studies at Pennant Hills. The property was transferred to the Concord Senior Citizens Association on 4 February 1991.

Assessment of significance

SHR Criteria a)
[Historical significance]
No. 10 Thornleigh Avenue illustrates the break up of the semi-rural Thornleigh estate into suburban residential allotments just prior to WW1. The house, built c.1920, provides evidence of suburban development in the late Federation and Inter-War years and of the building boom in the former Municipality of Concord during this time.
SHR Criteria c)
[Aesthetic significance]
The house, including interiors, at No. 10 Thornleigh Avenue is an intact substantial Federation style house with excellent features, and its prominent position makes it a striking streetscape feature. The attractive front fence, which shows the influence of the Inter-War period, complements the house and makes a positive contribution to the streetscape.
SHR Criteria e)
[Research potential]
It may be that the relatively intact interiors are rare. Further research is needed.
The association of the property with the Redemptorist Fathers requires further research.
The house may have been designed, and construction started, prior to WW1, this accounting for its Federation period style. Further research on the house would assist with understanding its history and design.
SHR Criteria f)
Two storey Federation mansions are relatively rare in Canada Bay LGA.
SHR Criteria g)
Intact Federation period house (including interiors) and front fence with excellent features.
Integrity/Intactness: The original allotments of the first suburban subdivision remain. The property, including house, interiors and front fence, is highly intact.
Assessment criteria: Items are assessed against the PDF State Heritage Register (SHR) Criteria to determine the level of significance. Refer to the Listings below for the level of statutory protection.

Recommended management:

1. The Heritage Schedule of Canada Bay LEP should be amended so that the listing specifically includes the house interior the front fence as well as house and garden. 2. Further research should be undertaken on the history and fabric of the house. 3. The existing scale, form, original materials, original pattern of openings, and original details - including all original timber joinery should be retained and conserved. No new openings should be made in the front façade. Any alterations and additions should be restricted to the rear of the building and site. All chimneys should be retained. Fae brickworks should not be painted. 4. A schedule of conservation works should be prepared for the house (including interiors) and front fence. 5. Urgent maintenance works should be undertaken, including painting and repair of the timberwork. 6. A landscaping design should be prepared in order that an appropriate setting can be provided for the house. The current location of the entry path should be retained. 7. The front fence to be carefully repaired using appropriate materials and salvaged bricks so that the repaired fence matches the existing. 8. Currently the house and grounds extend over four allotments. If the allotments are to be reformed, the garage and driveway should be located on the same allotment. This is because the current location of the garage and driveway is the most favourable. A garage set behind the house and entered from Thornleigh Avenue would adversely impact the setting and amenity of the house. If the house is ever considered for sale, sufficient area to the west of the house for a large private garden should be included so as to be commensurate with a scale of the house. 9. The residential use of the house should be retained, preferably for a single family in accordance with the original use
