The court is a Grade II listed building, and its present appearance is due to a major rebuilding undertaken by William Burn for Charles Grenfell in 1855–1860.

[3] It was inherited in 1867 by his grandson William Grenfell, 1st Baron Desborough where a prominent social role was also played by his wife Ettie.

Visitors included Henry Irving, Vita Sackville-West, Edward VII then Prince of Wales, Winston Churchill, H. G. Wells, Patrick Shaw Stewart, Edith Wharton and Oscar Wilde.

After World War II, Taplow Court was owned by British Telecommunications Research, a subsidiary of Plessey Electronics until 1988 when it became a Soka Gakkai International(SGI) Buddhist centre.

Historic England describes Burn's chosen style for the exterior of the court as "early Tudor", and its interior as "Romanesque".

[9] The interior contains a double-height hall, enclosing the Elizabethan inner courtyard, which was undertaken for Lord Orkney and has been attributed to Thomas Hopper, the architect of Penrhyn Castle.
