Description

Tremafon is a house that features a rock-faced rubble lower section and a timber-framed upper floor front, which is infilled with finely laid red brick. It has slate roofs and is bilaterally symmetrical in design. The entrance doors are located near the center and are separated by a projecting stone screen wall. Each outer bay has a wide gable that jetties from black painted jowled timber posts, which rise from an outsetting plinth. The gables have vertical studs with small curved braces in the end bays. The roof projects outward, with bargeboards that are cut with openwork acorn motifs inspired by the family arms. There are red brick stacks on the inner side of each gable. The windows are leaded wooden, with the main gable window being six lights wide, and there are gabled dormers above the center bays that have similar but smaller bargeboards. The ground floor windows feature blue-brick sills set in stonework. A datestone is set in the wall of Tremafon, carved with family arms and the initials D.W.S, dated 1912. It is noted that the windows and door of Brynawel have been replaced.
