The architect was likely R. Kyrke Pearson from Oswestry, who redesigned Newton House for Lord Dynefwr.

The interior has an open, arched-brace roof with collar-beams and stone corbels, and a window in the south wall from the 13th century from the previous structure.

In 1961, the font and stained-glass window war memorial were removed to nearby St Teilo Church for safekeeping.

[1] The building was used as a visitor's information centre by The Welsh Wildlife Trust in the late 1980s and early 1990s.

The building was listed at Grade II on 18 March 1988, as a "church of moderate architectural interest in an exceptional location at Dynevwr Park, with a fine steeply sloping burial ground with old headstones".
