The Church is located in old Chiswick, very close to the river Thames and Chiswick Mall. The older tower dates from early to mid 15th century, constructed in Kentish Ragstone, while the church dates from the rebuilding in 1882 –84 under John Loughborough Pearson. Walls externally are of rough Kent Ragstone, with Bathstone dressings to most openings. The south porch is open on three sides, with elaborate fan-vaulting over the arched orders.
Inside, the church is characterised by a sense of generous height and width, the arcades being slender and the aisles rising nearly as high as the nave. There is no clerestory. The abundance of fine fittings, screens, memorials and chancel reredos (Pearson) and Lady Chapel reredos (W.D. Caröe) helps to enrich the somewhat uniform treatment of the ashlar wall masonry, whose joints are all crisply expressed by the use of terracotta-coloured mortar. The floors are a combination of original Victorian encaustic and later buff coloured tiling, with parquet blocks laid herringbone-fashion under the pews.
