National Gallery Extension

The extension was situated in a portion of St George's Barracks Yard. New storerooms were added to the basement, three rooms to the ground floor, and five rooms to the first floor.

The exterior follows the style of the gallery's eastern side, as the brief required it to fit harmoniously with the existing architecture. The west elevation uses the same Portland stone.

The lighting arrangements were improved by using top lights, reinforced with concrete ribs. The materials (steel glazed with wired glass) were chosen for their fire resistancy.

The ornamental designs were intended to be unobtrusive, so detail is gathered in the ceilings and cornices. To both, modelled fibrous plaster work is added.

The door openings are central features of the interior design, and are enlarged by over-sized architraves. They are also fire resistant. The floors are polished oak, and defined by margins of black marble.
