The 1904 Public Works Report states (at p45): "Disinfecting Station, Kowloon. Including Quarters for Inspector.—The contract for this Work was let in October, 1903, but was only commenced in December as the site for reasons previously stated had to be altered. It consists of a disinfecting shed in two compartments each 29’ 6” by 25' 0.”; a two-storey store with concrete ﬂoors 49' 6” by 24' 6”; an office 16' 0” by 14' 0”; a store 20’ 0 ' by 14’ 0”; an office for the Medical Officer of Health 34' 0” by 16’ 0" with two rooms under it; Coolie quarters, bathrooms latrines, &c.; Inspectors’ Quarters 4 rooms 16’ 0” by 14’ 0” with coolie quarters, kitchens,'&c.; the whole contained within a boundary Wall with a yard about 95’ 0" by 70’ 0”. The present site entailed a great amount of piling owing to the presence of a lot of silted up stream beds and layers of sand, in some cases 10 or 12 feet deep. The whole of the works were’ ﬁnished by the end of the year with the exception of sorne concreting in the yard and the Medical Oﬁieer of Health’s office, the latter being an addition to the original contract and estimated at $5,000. The disinfecting shed with its apparatus was handed over to the sanitary board for use in May and the ofﬁce and stores with half the yard in November, which allowed them to give up the use of their office at 29 Austin Road."
The 1905 Public Works Report states (at p42): "Disinfecting Station, Kowloon. This work was completed and handed over to the Sanitary Board in April. The buildings occupy a convenient and central site, 19,300 square feet in area, at Yaumati, and are built of red brick, pointed in cement, with mouldings, window sills, arches, &c., ﬁnished in cement plaster. A statement of the accommodation afforded appeared in last year's report. The total expenditure on the work was $40,219.13, which includes the cost of a new boiler and vacuum pan, amounting to $3,136.62." The roadworks to enable access to the site are also mentioned at p65 of the same report.
