In addition to Windmill Street itself from the railway southwards to Clarence Place and Wingfield Road, the area includes properties in Zion Place, Victoria Avenue, 6 to 24 Wrotham Road, 20 to 24 Stone Street and The Railway Tavern in Railway Place.
The area, up until the 1820s was generally undeveloped, apart from a few isolated dwellings along Windmill Street. Many of the properties which now exist, particularly along Windmill Street, were built to meet the demand for accommodation when Gravesend was popular as a resort in the first half of the nineteenth century. Windmill Street became Gravesend's principal residential thoroughfare, with hundreds of visitors passing along it on their way to Windmill Hill from steamers which plied between London and the Town Pier.
Windmill Street south from the Civic Centre has by far the finest buildings in the conservation area. It contains a variety of styles and ages of buildings from the very modern, for example William House, which are sympathetic to the general character of their older neighbours, to the oldest, which are Georgian in origin. By far the most remarkable feature is the grouping of Nos. 70 and 71 into an impressive four-storeyed ornate classical composition with splendid ironwork and stucco detailing. This pairing of two semi-detached houses to make a grand architectural effect is also the basis for 109-110 and for a sequence of paired houses. In the commercial part of the area, the scale is still largely domestic but the Civic Centre with its open forecourt dominates.
In Wrotham Road, pleasant mid- and late-Victorian houses have been colonised by local businesses and the proximity of the Civic buildings makes this part of the area more of a 'corridor' than is Windmill Street. Zion Place and Victoria Avenue are more domestic in scale. Both are attractive terraces.
