Boiling house at Tyddyn Isaf

Lofted boiling house, built of rubble masonry with widely slobbered mortar; slate roof with tiled coping and rectangular dressed stone stack with capping at R (W) gable. The ground floor openings have large stone lintels, doorway to L and 12-pane hornless sash window with slate sill to R. There is a small window to R set under the eaves and entry to the loft via an external flight of stone steps at L (E) gable.

All the cooking was done in the boiling house until mid C20. The range still retains the large inglenook with massive bressumer at W end; the hob and oven to R (N) of a stone pier, formerly with boiler to L.
