The architect Arthur 0. Evans, of Pontypridd, drew up the plans for a new Baptist Chapel, c.1905, and wrote out the specification for the contractors. His preparation gives an insight into how a chapel architect would define his design for a new temple, carefully denoting everything from the kind of slate (‘best North Wales slates from a quarry to be approved by the Architect’) to the number of nails to be used to secure the floorboards (‘two’), and the choice of a ‘wrought iron gothic latch’. There follows a verbatim transcript of his handwritten instructions:
