The houses are typical of the many brick-built terraces of houses built in Ashton and other Lancashire towns. The windows have plain stone lintels and cills while the doorways have a decorative arch above a semi-circular fan-light window.
The fanlight over the door indicates that the houses have porches or hallways inside, and these windows provide daylight for these. By contrast, the more basic style of house had its front door opening directly into the front room and so had no need of a fanlight. Another feature of these houses is that the lower courses of the wall are built from stone, now painted.
