Later houses are much more varied in character, as the advent of rail transport led to a greater variety of affordable building materials. William Wilkinson, architect to the St. John's College estate, designed houses in Richmond Road and Walton Crescent in the 1860s with fashionable polychrome fronts using stone and bricks of several colours. Builders too followed fashion to make their houses more appealing and some Cranham Street houses, for example, have Gothic heads to doors and windows, echoing grander North Oxford properties. Bay windows make an appearance in Juxon Street, emphasising the individuality of each house. These, like the later houses in Richmond Road and Walton Crescent, are set back from the pavement behind front flower gardens, like the early terraces in Walton Street, but very different from the older streets in the heart of Jericho.
