Annex / Nurses' Quarters
The four-storey annex housing the hospital's nurses was built first, before the hospital itself — rusticated brick over a high concrete foundation on the lower two storeys, smooth brick with corner quoins above, under a moulded sheet-metal dentil cornice. A drug room stood at its east end and a laundry in the basement.

The powerhouse was built at the high northwest corner of the block, one tall storey over a basement in rusticated painted brick under a sheet-metal cornice and stucco parapet, with a stuccoed stack rising about thirty feet and a steel extension above it. It held two 75-kilowatt generators and two boilers, and basement tunnels ran from it to a coal and oil vault under the Lyon Street pavement and across to the annex.
