Llys Model (former Model School)

Llys Model is a Gothic school building dating to the 1850s, originally comprising a main block and associated ranges. The building is constructed of squared rubble stone with ashlar dressings, featuring steep slate roofs and coped gables. All windows have been replaced with uPVC frames.

The main front elevation features a gable to the left, indicating a rear classroom wing, and a former domestic range to the right, which screens a rear range containing dormitories above two small classrooms, with a teacher’s house beyond. The front gable includes a cluster of three trefoils above an altered pair of two-light schoolroom windows, now divided by an inserted floor and with cusped heads to each light. The range to the right has a shouldered doorway, a two-light mullion window under the eaves (initially depicted as a three-light in a historical sketch), and two bays of two-light windows, with upper windows positioned in stone eaves dormers (the sketch showing one two-light and two three-light windows under the dormers).

The west side of the schoolroom wing incorporates a large, coped gabled former girls' porch on the right and an altered former boys' porch on the far left, lacking coping. The right porch has a chamfered pointed arch with a cusped head and a low side-buttress. Between the porches are five gabled schoolroom windows with later 19th-century yellow brick sides and glazing extending into the gables. Later 20th-century glazing divides the windows between floors, with the central bay containing glazing down to a 20th-century door. The former boys' porch on the left has been infilled.

The east end of the front range has a lean-to and lacks windows, while the rear north wall has a single, large, cambered-headed yellow-brick window of the late 19th century, with a 20th-century skylight above.

The rear north-east range is in three parts and has been largely rebuilt. The first section has three small, rectangular first-floor openings, connected to a second section with four larger 20th-century upper openings lacking dressings (originally all seven windows illuminated dormitories). Both sections have a broad, segmental-arched ground floor schoolroom window with stone voussoirs, flanked by yellow-brick framed rectangular windows, one of which is now a door. The former schoolmaster’s house to the right has been significantly altered, featuring a three-light ashlar mullion window with a relieving arch, a small doorway with a segmental-pointed red brick head, a chimney breast, and three flush Velux roof windows. A previous description from 1981 noted an external stone stack and a gabled two-light mullion window above the doorway. Further features of the 1981 description include a north-end three-light mullion window to the first floor, a four-light window to the ground floor, both with relieving arches, and a small cusped lancet window to the ground floor right.

The north end of the west classroom wing, set back to the right, has a large pointed window with stone voussoirs and 20th-century glazing, lighting two inserted floors.

A near-detached single-storey classroom to the rear northwest features a steep slate roof and coped gables. Its east side contains three two-light mullion windows with renewed glazing and three inserted skylights to the roof. The south gable end has a three-light window with a pointed relieving arch, with a taller, cusped-headed centre light, a blank trefoil in the apex, and a stack.

The building has been converted to flats, resulting in alterations to the original fabric.
