St Mark's Infant School

St Mark's Infant School is a church elementary school built between 1866 and 1867, designed by architect Benjamin Ferrey and funded by Philip Cazenove on land donated by Earl Spencer, Lord of the Manor. The school is constructed of stock brick with red brick bands and features a tiled half-hipped roof, with large polygonal stacks positioned at the angles and at the rear. It has an irregular plan due to its location on an apex site and is a single storey building. The roof extends over dentiled eaves.

The schoolroom has large timber casement windows with square panes that project into the gable, set within polychromatic pointed recesses. One of these windows, facing the road, is inscribed with "ST MARK'S SCHOOL 1866." The windows on the rear elevations have been renewed, and there are doors in projecting porches, one featuring a pointed arch and the other having been renewed.

Although the interior was not inspected, it is noted to contain a single large schoolroom with an open timber roof, although a suspended ceiling of no interest has been added. St Mark's School is a rare and little altered example of a small church school in London, built during the development of Clapham Junction in the 1860s. Benjamin Ferrey was a prominent church architect of his time, and while he may have expected to receive the commission for the adjacent St Mark's Church, it was instead awarded to William White, a slightly younger and more radical Gothic architect. Together, the two buildings create a notable architectural group.
