 In 1850 , Thomas Coke , 2nd Earl of Leicester , called in the architect William Burn to build new stables to the east of the house , in collaboration with W. A. Nesfield , who had designed the parterres . Work started at the same time on the terraces surrounding the house . This work continued until 1857 and included , to the south and on axis with the house , the monumental fountain of Saint George and the Dragon dated c . 1849 – 57 sculpted by Charles Raymond Smith . To the east of the house and overlooking the terrace , Burn designed the large stone orangery , with a three @-@ bay pedimented centre and three @-@ bay flanking wings . The orangery is now roofless and windowless .
