[2] The Vale of Clwyd Railway had used a temporary stop at Denbigh from 1858 until their station buildings, which also housed their headquarters, were constructed.
[3] The Tudor Gothic-style station building, which incorporated accommodation on the first-floor for the station master, primarily used limestone, with detailing such as around the doors, windows and chimneys being of freestone.
The booking and left luggage offices were placed centrally, and there were three waiting rooms - a general room, one for ladies travelling first-class and another for those ladies travelling second-class.
There was an initially single platform, partly sheltered by a roof supported by cast iron columns.
That platform was extended in 1885 and altered also to allow trains to stop regardless of their direction of travel.
