 The front ( facing east over the gardens towards Backwell Hill ) and north ( entrance courtyard ) are faced in one shade of <unk> Bath Stone , while the south ( rear ) , which is mainly allocated to the service area and servants quarters , is faced in cheaper red @-@ tinged Draycott marble rubble , and has some plastered finishes . All facades have many Gothic main windows , Tudor oriel windows , chimneys and attic dormers . Norton topped the design with an irregular roof , its various pitches and gables emphasising the building 's asymmetrical architecture . The final external addition was a huge ironwork conservatory by Hart , Son , Peard and Co. to the rear . The end result was described by novelist Charlotte Mary Yonge , a cousin of Blanche Gibbs , as " like a church in spirit " .
