of the Corinthian order. Also he created the greenhouse (1789) (later altered by Jeffry Wyattville c. 1818) attached to the stable block, a grand riding-school (1789) demolished, indoor tennis court, demolished and Chinese style dairy (1789). Within the park he also designed a new entrance archway (1790), farm buildings, cottages and kennels. In 1801 he converted the greenhouse into a sculpture gallery to house the Duke's collection of Roman sculpture, adding the 'Temple of Liberty' at the east end to house busts of Charles James Fox and other prominent Whigs. Holland went on to design the Theatre Royal, Drury Lane, when it was rebuilt (c. 1791–94) as Europe's largest functioning theatre with 3,919 seats. The building was 300 feet in length, 155 feet in width and 108 feet tall. The Portland stone exterior was of four floors, rising a floor higher above the stage. The facades were fairly plain, with the main embellishments on the ground floor. A single-storey Ionic colonnade surrounded the building, with shops and taverns behind it. The auditorium was approximately semi-circular in plan, with the Pit. There was a row of eight boxes flanking each side of the Pit, two levels of boxes above, then two galleries above them. The stage was 42 feet wide and 34 feet to the top of the scenery. The Theatre Royal burnt down on the night of 24 February 1809. At the Royal Opera House he rebuilt the auditorium in 1792. The new auditorium contained a pit and four horseshoe shaped, straight-sided tiers. The first three were boxes, and the fourth was the two-shilling gallery. The ceiling was painted to resemble the sky. In addition Holland extended the theatre to provide room for the Scene Painters, Scene Room, Green room, Dressing Rooms, etc. The theatre burnt down on 20 September 1808. From 1802 Holland converted York House on Piccadilly into the Albany apartments. In 1796 Holland started remodelling Southill House Southill, Bedfordshire for Samuel Whitbread with work continuing until 1802. The exterior was remodelled with loggias and a portico with Ionic columns and the interiors completely modernised in the latest French Directoire style. The finest interiors are the library, drawing room, dining room, Mrs. Whitbread's room and the boudoir. In the garden Holland created the north terrace and the temple with four Tuscan columns. In 1796 Holland received the commission to design the new headquarters for the East India Company,
