Plate XVI. Square Plans Disposed for Interior Effect

Plate XVI. — These schemes are especially appropriate where it is desired to produce interior architectural effect in a hall or vestibule of small dimensions which forms the meeting point of two or more suites of rooms. In No. I such an apartment is shown with a saucer dome carried on pendentives: a circular entablature intervenes between the pendentives and the dome. No. II shows the simplest treatment for a square apartment either with a flat ceiling and cornice as shown, or with a regular entablature proportioned to the height of the room. In No. III the proportion of a cube is followed with the introduction of a cove one quarter to one-fifth of the total height: this produces a square panel in the centre of the ceiling and emphasises the shape of the apartment. No. IV shows a square apartment ceiled with true cross vaults, thereby admitting light on four sides at an upper level. In marked contrast to this is the “cloister vault” or high coved ceiling shown in No. V, which has concave groins and leaves a square panel in the centre. No. VI shows how a square can be developed into an octagon at a higher level by means of semi-vaults meeting at the points of a central octagonal panel. In No. VII is seen a type common to Italian practice, in which the Order is omitted and a geometrical disposition of groined coves supports a flat ceiling in the centre.
