Treliske School

Treliske School is a country house, dating from around 1880, originally built for Sir George Smith. The construction utilises granite ashlar with a dry Delabole slate roof covering the left-hand wing, while the remainder has been replaced with asbestos slate. The main roof is hipped, and there are stone axial and lateral stacks. The building follows a substantial double-pile plan and incorporates a service wing at the rear. The front includes two reception rooms flanking a central entrance hall, with an axial passage behind the left-hand room and a stair hall behind the right-hand room. A conservatory and billiard room are located on the left, and a summer room on the right. The architectural style is Classical with Mannerist details.

The symmetrical entrance front is arranged as a 2:1:2-bay composition, with the central entrance bay projecting and topped with a steep triangular pediment featuring an oculus. Features include a plinth, a moulded first-floor sill, and a moulded eaves cornice. The ground floor entrance has a distyle-in-antae porch with a stepped, stilted, round arch over the doorway, flanked by narrow sidelights. Above this is a blind arcade supported by moulded brackets. The flanking bays have elliptical arches with rock-faced voussoirs and projecting keyblocks above two-pane sashes. The first floor has a central tripartite sash with two-over-one panes, and similarly styled sashes to the flanking bays. Original windows are present throughout. The conservatory on the left features a symmetrical three-by-two-by-three-light front, with a taller central segmental section above a pair of doors rising into a gabled dormer, and margin panes to the windows, many retaining original coloured glass. The summer room on the right has a symmetrical front with three pairs of lights. The other elevations are similarly styled but plainer, and retain most original features.

The interior remains virtually complete as originally built and boasts a high standard of carpentry, joinery details, and plasterwork, with moulded and carved cornices in most reception rooms. The entrance hall has a heavy, modillioned cornice, and a doorway, flanked by slender columns with near Ionic capitals, leads to a large stair hall. The stair hall features a mahogany handrail over a cast-iron balustrade with scrolled newel posts and a fine stained-glass window. Several fine quality chimneypieces and doorcases are also present. The summer room has an open hammer-beam pitch-pine roof structure, boarded between the trusses.
