Description
Brynau is a house dating from the early 20th century. The front elevation faces east, towards the garden. It comprises a central three-bay gabled block which projects forward, with further blocks stepped down to the left and right. The front is constructed of brown stone, while the rear and sides are pebble dashed. The roof is tiled, with brick chimneys. Casement windows are present throughout, with labels above some. The central gable features a casement window at attic level, with a label above it. The front door is ogee-headed and situated within an open porch with benches to either side; the door itself is gothic. The outer bays on the front have casement windows with labels. An advanced block to the left features a large, splayed bay window. To the right, blocks are stepped down, each with a single casement window. Outshuts and additions are present at the pebble-dashed rear.
