Windows

This house was highlighted in the Aberdare townscape survey as having extravagant render detailing and being an example of the late nineteenth century trend towards middle class homes with bay windows. http://cadw.wales.gov.uk/docs/cadw/publications/urban_character_aberdare_EN.pdf
Unfortunately over zealous repairs to the bay window roof led to the collapse of the bay and its replacement with a plastic one.

This is a perfect example of the gradual loss of the small details that help make buildings and towns distinctive. Each change is small and relatively insignificant but the small changes add up so that soon it becomes impossible to find original features like doors and windows. Interestingly the  bays and other detailing on this terrace are actually made from cast stone. They were probably bought from a catalogue as there are identical bays in nearby Abernant.
