In making choice of an interesting type to be followed in the British Royal Pavilion at the Louisiana Purchase Exposition, it was felt that the Orangery of the Royal Palace of Kensington would be representative of English domestic building at one of its happiest periods, and a tribute also to the memory of the great architect, Sir Christopher Wren. In the Orangery of Kensington was found a building that could be strictly reproduced to its real size. The Orangery was 170 feet long and had a range of sash windows uninterrupted by doorways, the central and end windows having stall boards under them, making the entrances. The long line of roof was broken only by the three brick parapets or pediments, the center one being carried on half-round columns and pilasters of gauged brickwork. The walls were of red brick and stock brick spaced out with design, imitation white stone being sparingly introduced in cornices or keystones to give a note of white in the color scheme. The long hall ended in circular anterooms. In the replica, at St. Louis, of Wren's building, the only departure from the original was the introduction of an enriched plaster ceiling, such as would be found in a house of the period; the real Orangery was left bare and whitewashed. The architects used the Orangery as the principal front to a quadrangular building, the necessary offices and accommodation for royal commissioners and executive staff being provided in wings that led from the two circular anterooms. The fourth side of the open court was made by a colonnade, the royal arms being above the central opening. The character and details of the Orangery were carried through as far as possible, so that harmony and unity was given to this pleasant composition. In the garden surrounding the pavilion an attempt was made to reproduce on a small scale the style of garden that was generally attached to the mansion residences in England during the reign of William III and Mary, in the latter part of the seventeenth century, and at the time of Queen Anne, in the early part of the eighteenth century. The old-fashioned garden with characteristic features of shady terraces of "peached alleys," as they would be called, inclosed by hedges clipped into shapes and embellished with topiary work with the forms of animals and birds cut out of yews and boxes attracted much attention. The garden was filled with old-fashioned flowers. A water basin and fountain, typical of the old English gardens, were there, as also were stone statues and lead urns and vases. The garden became one of the sights of the exposition and was usually crowded with interested and delighted sightseers.
