Llys Trefor

Llys Trefor consists of nine consecutive cottages located on Gwynant Street, built from roughly-squared stone blocks and topped with a continuous slate roof featuring a tiled ridge and plain, shared chimneys. There are visible masonry breaks between cottages 2 and 3, and between cottages 8 and 9, indicating different building phases. Cottage 9 is a two-window unit with a central entrance, while the other cottages are single-window units arranged as reflected pairs, each with alternating paired inner doors and windows. All the doors are from the 20th century, mostly modern.

On the ground floor, cottage 6 (Hebog) has a 12-pane sash window, while cottages 2, 4, 7, and 9 feature later 19th-century plain sashes. All cottages except for 1 and 2 have returned slate labels and slate lintels above their ground floor windows. For the upper windows, cottages 2, 7, and 9 retain their original 19th-century 9-pane sashes under the eaves, and cottage 6 has a 12-pane sash; the remaining upper windows are modern. This group of nine cottages is architecturally significant.
