One of the first exponents of C18 Gothic Revival, as early as 1749 Keene assisted Sanderson Miller to prepare drawings for Hagley, Worcs., and in c. 1750 he fitted out the chapel at Hartlebury Castle, Worcs., in the Gothick style. He designed the octagonal Hartwell Church, Bucks. (1753–5), and Sir Roger Newdigate, Bt.
