Coed-y-Celyn

Coed-y-Celyn is a two-storey building with a five-window northern front and a four-storey central porch or tower. It features shallow pitched slate roofs with wide eaves, curved brackets above a string course, ironwork finials, and paired stacks on the left side. The building has arched windows with cill and impost bands, and a pedimented tablet displaying the Lovat coat of arms. The tower top includes a four-window arcade supported by paired granite pilasters. Above the porch, there is a bipartite window with richly carved spandrels and double doors leading up steps. To the left, there is a four-window lower service range, possibly built in 1874, which lacks Bath stone dressings and features painted ironwork lintels and tripartite windows on the ground floor. A low wall with ornamental railings extends forward to the left, flanking the yard entry. The elevation facing the river has twin gables, and the lower rear block has embossed metal lintels dated 1874.

The interiors of the main ground floor rooms along the south and west fronts are richly decorated and accessed via a long spinal corridor with a mosaic floor, strapwork friezes, modillion cornices, and foliage stained glass in the porch. The drawing room and music room are en suite, featuring elaborate plasterwork and coved cornices. The walls have Adamesque panels with medallions, and there are paired Corinthian columns leading to the double doors. A sumptuous white marble chimney piece with figure supports is believed to have been displayed at the Great Exhibition in 1851. The richly carved pelmets, mirrors, and other fittings are said to have originated from the Old Imperial Palace in Peking. The rear ballroom, which is in a ruinous condition, is top-lit and features a coved stencilled ceiling along with an arched and pilastered exedra.
