It is designated by Cadw as a Grade I listed building,[1] and is under the care of the Friends of Friendless Churches.

[3] The church was designed by Henry Wilson who was a "leading figure of the Arts and Crafts Movement".

[2] The church is constructed in brick, and faced with local grey-green ashlar stone; it has slate roofs.

The "external stonework was intended to be left 'untooled' (rough)",[2] because the architect "wished the church to appear as if it had sprung out of the soil, instead of being planted down on it".

It was cast at the Central School of Art and Design in London, and is decorated with leaf patterns and Christian monograms.

The stalls in the chancel are made from Spanish chestnut; they were designed by Wilson and carved by Arthur Grove with zoomorphic images.

[8] The church is listed Grade I by Cadw because it is "a highly important and unaltered example of the work of Henry Wilson, a leading figure of the Arts and Crafts Movement.

[4] "The interior decoration and fittings are arguably the most complete and high-quality Arts and Crafts work in Wales.
