thumb|right|Chalford Roundhouse at the site of Chalford Wharf A number of the buildings associated with the canal have survived and appear on the listed building register, including five circular cottages, built with three floors. The lower floor was intended to be used as a store and has access to the outside. A set of outside steps leads up to the first floor, which is around in diameter. It was designed as a living area and was equipped with a cooking range. A staircase, built between the inner and outer wall, leads up to a circular bedroom on the second floor. The round houses are situated at Lechlade (the Round House, Inglesham), by the entrance lock from the Thames; at Marston Meysey; at Cerney Wick near Latton, next to lock 39; at Coates, close to the eastern portal of the tunnel; and at Chalford, next to lock 13. Some had a pointed slate roof, while others had a lead cone, which collected rainwater for drinking. They were built in the 1790s for use by lock-keepers and lengthsmen, but were not particularly popular due to the limited amount of space and problems with finding suitable furniture for a circular room.
