Self build, including plumbing and electricity. Large living space upstairs, benefiting from wood stove downstairs in hall. Mostly open plan. Very rural, once part of the Leyton estate (Welshpool).

All external walls insulated on the inside together with 14 leaf insulating foil. Foam seal under slates, 14 leaf foil plus 60 mm. Kingspan. Plasterboard throughout the house is ‘moisture board’ quality.
