9 and 11 Lyon Street, Dundee

19 Lyon Street in Dundee is a terrace of five tenements built in 1866-67 for the millworkers of Dens Works. These four-storey tenements are constructed from coursed and squared rubble and feature rear platties.

The elevation facing Lyon Street consists of 29 bays, made up of five six-bay tenements, with the end block on Albert Street having five bays. There is a ground floor band course, and some doors have been altered to windows. The building includes three pends. The side elevations have two bays, with the one facing Erskine Street being blind, and a wallhead stack has been removed. The corner at Albert Street features a chamfered angle with a ground floor shopfront, and one bay is blind. There is a shouldered wallhead stack.

At the rear, there are five open-topped semi-circular stair towers with flagstone platforms supported on curved iron brackets and light iron frameworks, which have been altered to steel in four cases. Brick blockings indicate where lavatory towers were added and later removed. Four of the stair towers are harled.

The original piended slate roof has been replaced with concrete tiles, except for numbers 1-7, and the tall ridge stacks have been removed.
