Tan-y-bryn

Tan-y-bryn and Bron Derw are a pair of intentionally asymmetrical estate cottages built in a rough L-shape. They are located in Abergwyngregyn and date from the period when the estate adopted a mild Gothic style for its village buildings, while also reflecting influences from the emerging Arts and Crafts movement. The cottages are constructed from snecked rubblestone, featuring large slate-stone lintels. The first floor is slate-hung, except for a short section of the long range at Tan-y-bryn. Both cottages have slate roofs with bargeboards on the overhanging verges, and the gable ends of Tan-y-bryn display decorative king-post trusses at their apexes.

Bron Derw features a wide gabled dormer on the right that breaks the eaves, containing an inset 2-light 12-paned window above a similar 3-light window on the ground floor. There is a roughly central 20th-century half-glazed door beneath a bracketed lean-to hood at the angle with a slightly projecting lean-to on the left. This lean-to has a 2-light 12-paned window on the ground floor and a 3-light flat-roofed dormer with a pediment directly above. The integral end stack on the right has a rendered base and two diagonal brownish brick shafts with stepped capping, while a similar stack on the left behind the ridge has three diagonal shafts.

Tan-y-bryn has two 2-light 12-paned casements centrally placed on the first floor of its projecting gable, with 2- and 3-light mullioned and transomed windows with glazing bars to the left and right, respectively, of a narrow chamfered rectangular window on the ground floor. There is a hip-roofed largely glazed porch at the left return, in the angle with the short continuation of the long range, which has an integral stack with paired diagonal shafts and two 2-light 12-paned windows on the first floor of the left gable end. A prominent stack with three clustered diagonal shafts is located in the roof slope of the right return of the gabled range. The interior was not inspected at the time of the survey.
