Chastleton House

It was built c1886-87 for Martin Petrie Blundell, a leading banker with the Bank of Australasia in a highly picturesque asymmetrical composition. The house changed ownership in 1905, and new owner, William Barrett, maltster, commissioned notable Melbourne architect George De Lacy Evans to oversee major changes to the house including the construction of the new elaborate frontage in 1907. De Lacy Evans was responsible for the elaborate classical design of the new front porch which was engineered by the eminent engineer John (later Sir John) Monash using the novel Monier-system of reinforced concrete construction.

Chastleton House is significant to the extent of its intact c1940s external form and fabric. The legibility of the built form in views from its two street frontages, Chastleton Avenue and Orrong Road contribute to the significance of the place.

Modern alterations and additions such as the garage to the north-west corner and contemporary fence and landscaping are not significant.

How is it significant?
Chastleton House at 17 Chastleton Avenue, Toorak is of local architectural, aesthetic, and technical significance to the City of Stonington.

Why is it significant?
Architecturally, Chastleton House at 17 Chastleton Avenue, Toorak is a distinguished example of a prestigious and substantial Victorian mansion built for a prominent Melbourne resident during the boom years of the late 1880s and 1890s. The changes to the house c1907 provide an important example of the later residential work of the architect, George De Lacy Evans, illustrating the development of the Victorian Italianate style in Melbourne. (Criterion D)

Aesthetically, it is particularly distinguished within the City of Stonnington by its substantial size and complex massing that creates a highly sculptural composition. It combines the stateliness of a classical style with a picturesque and fashionable asymmetry, reflecting its creation over time. Its elaborate classical detail is exemplified by the entrance porch at the centre of the facade, instead of the typical verandah. It adopts a sculptural entrance portico of a classical balustraded entablature supported on stop-fluted Tuscan columns and square piers which is linked at the first floor level by a parapet wall with pediment and shield details. The composition is further distinguished by the central landmark tower with pedimented pyramidal roof. The classic Italianate villa appearance is apparent in the projecting gabled bays to the east and west elevations that retain the closely spaced eaves brackets and pediment window hoods. Fine cast and run cement render detail to the entrance portico, window surrounds, eaves brackets and the elaborate front door contribute to the highly ornamented composition. (Criterion E)

It is significant for its entrance portico 1907 which is a pioneering example of the Monier-system of reinforced concrete construction in a domestic context designed by the eminent engineer (Sir) John Monash. Architect De Lacy Evans was responsible for the elaborate classical design which was engineered by Monash to adopt the innovative Monier-system, including Monier plates to the roof, square piers of brick, and Monier concrete with render to the round columns. It is one of Monash's earliest experiments using the system in a residential context and only one of two known in Melbourne. Monash's experiments led to the prolific range of engineering structures constructed by his Reinforced Concrete and Monier Pipe Construction Company, including bridges, arches and pipes.
