The Swiss Cottage, Rockfield, Monmouthshire is a gatehouse to The Hendre estate and was designed by Sir Aston Webb in 1905.

The Hendre was the country home of the Rolls family since the 18th century[1] and, as the fortunes of the family rose, was subject to three major expansions in the 19th and 20th centuries, to the designs of George Vaughan Maddox,[2] then Thomas Henry Wyatt,[2] and finally Aston Webb.

[2] Webb constructed the Cedar Library at the main mansion in the very late 19th century[2] and in 1905 designed the Swiss Cottage.

[3] It formed a terminal point on the “3-mile Drive” constructed by Lord Llangattock, and designed by Henry Ernest Milner.

Cadw notes influences from Lutyens and Voysey,[3] while the Royal Commission on the Ancient and Historical Monuments of Wales considers it "an inspired and unusually distinctive symmetrical Arts-and-Crafts design".
