Cotton House

Cotton House is a building designed in 1870 and constructed between 1871 and 1872, created by architect G.E. Street. It was built using concrete through the patented method of Charles Drake, with cement rendering. There is some tile-hanging under the eaves, but the material is largely exposed. The building features brick strings at the plinth and first-floor sill levels, and it has pitched tile roofs along with tall brick stacks that have elaborate cornicing.

The structure consists of three storeys and basements, while the study and dormitory wing has two storeys and attics. It has an irregular plan, with each section topped by its own pitched roof and very steep proportions. The windows are mullioned and transomed casements set in flush frames, with moulded cornices above (the second floor lacks transoms). The study windows are single-light. On the south side, there is a two-storey bay, with the first floor decorated with fish-scale tiles. The dormitory features two attic dormers that have tile-hung cheeks and rendered gable ends, which display simple pargetting with vaguely zodiacal patterns. There are two doors leading to the housemaster's area and the boys' section, both of which are planked and fitted with contemporary iron hinges and a mullioned oblong fanlight.
