History

Farmhouse and buildings, part of a small farm complex built c. 1806-7, as New Farm, for Thomas Johnes of Hafod, replacing the Home Farm nearer the house which was demolished c. 1806-7. Altered in later C19.
The farm was approached by a (disused) drive from the Jubilee arch built 1809-10 and is referred to in the sale catalogue of 1832 as 'formerly Mr Johnes' experimental farm'. It then had 270 acres (109hs) with an annual value of £61/15/0d (£61.45). Marked as The New Farm, farmed by John Howell on 1847 Tithe map. It was named Gelmast (said to be a corruption of 'gallant mast') by 1881, when a Capt. Rowlands was resident.
New Farm was probably intended to showcase Johnes' ideas on grassland management, stock, and dairying, and to supply milk, butter and cheese to the district, including the lead-mining area. The buildings relate mainly to the dairying (though Malkin in 1807 refers to a sheep-farming enterprise). The crown surveyor in 1845 noted that 'Mr Johnes built a farmhouse and office with a Dutch shed'.
The farm was unusual in having a formerly-detached dairy and large cowshed for abut 20 cows. There have been later alterations: the house has C19 stucco and windows, the blocks to E and W are probably altered (though both appear on the 1841 Tithe map): the service range to E is probably added in early C19, as it seems built across the front of the once-detached pyramid-roofed dairy. The open-bay cartshed to W was probably 'the Dutch shed', and the small lofted building further W was possibly a lofted stable (loft floor since removed).
The W side of the court has a detached barn, listed separately.
