The house was originally known as Kent Villa.

Federation University website listing Henry's many architectural projects.
To be confirmed: I have found conflicting references as to whether the original number was 32 or 34.

Webster Street is now being ornamented by a new and what promises to be a handsome and commodious dwelling, for Mr. Caselli, the architect, and after his own design. The house is already ready for roofing in, and is three stories high, including a half-buried basement. Both of the upper stories have a bay window in front, and when finished the elevation will be very presentable. The materials are of brick on the bluestone basement story, and the erection is not by the usual contract fashion, but the proprietor supplies his own materials and chooses his own workmen. There are nearly twenty rooms in the building, and the cost will be about £1400.
