Park House, 20 Park Place, Cardiff, Wales, is a nineteenth century town house. It was built for John McConnochie, Chief Engineer to the Bute Docks, by the Gothic revivalist architect William Burges. It is a Grade I listed building. The architectural historian John Newman writes that the architectural style of the house "revolutionized Cardiff's domestic architecture," and Cadw considers the building "perhaps the most important 19th century house in Wales."

William Burges was an English architect and designer. Among the greatest of the Victorian art-architects, he sought in his work to escape from both nineteenth-century industrialisation and the Neoclassical architectural style and re-establish the architectural and social values of a utopian medieval England. Burges stands within the tradition of the Gothic Revival, his works echoing those of the Pre-Raphaelites and heralding those of the Arts and Crafts movement.
