Maudsley Hospital Administration Block

The Maudsley Hospital Administration Block is a psychiatric hospital built between 1911 and 1923. The site was acquired in 1911, and the design was led by William Charles Clifford Smith, engineer for the Asylums Board of the London County Council. He was assisted by LC Gregory, who had consulted with Henry Maudsley, a pioneer in psychiatric hospital design, and Frederick Mott.

The building is constructed of red Southwater brick in Flemish bond, with Portland stone dressings. It has hipped slate roofs. The main building is a 23-window range, designed on a pavilion plan, with distinct end and central units. The main entrance is centrally located and features a Portland stone surround with a flat arch, a projecting cornice, and an architrave. Flanking windows have similar surrounds, incorporating a large rectangular block between the lintel and cornice. The upper windows are segmental-arched, with eared and shouldered architraves. The central section is treated as a "distyle in antis" portico of the Tuscan order, with the words "The Maudsley Hospital" carved into the parapet above. Ground-floor windows in the intermediate range have flat arches with flush stone surrounds and raking cornices to the centre lights. The projecting end bays feature segmental-arched ground-floor windows with eared and shouldered architraves and keyed lintels; flat-arched upper windows with similar surrounds; and flush stone corner quoins. Remaining upper windows have plain stone lintels. Each end pavilion is topped with a pediment containing a single oval light ornamented with stone palm fronds. A cupola is positioned above the entrance range, featuring rebated corners and pediments similar to those on the ground-floor windows. A second entrance is located in the right-hand end pavilion, set within an architrave with a projecting cornice. Fielded and corniced stacks are present on the left return and the fourth window range; ridge stacks align with the ends of the central pavilion.

The interior has not been inspected. Later 20th-century extensions to the left and right returns, and to the rear, along with attached railings enclosing a shallow porch on either side of the entrance, are not considered to be of particular historical interest and are excluded from the listing. This hospital was the first and most influential building of its kind and has significant historical value.
