Taplow Court is a Victorian house in the village of Taplow in Buckinghamshire, England. Its origins are an Elizabethan manor house, remodelled in the early 17th century. In the 18th century the court was owned by the Earls of Orkney. In the 1850s, the court was sold to Charles Pascoe Grenfell, whose descendants retained ownership until after the Second World War. The court then served as a corporate headquarters for British Telecommunications Research (BTR) an independent research company set up in 1946. BTR was subsequently acquired by Plessey Electronics. In 1988 it was bought by the Buddhist foundation, Soka Gakkai International and serves as their UK headquarters.
