Ty Pren

Ty Pren is a passive long house designed by Feilden Fowles and inspired by the rich local vernacular of the Brecon Beacons. Passive solar principles have driven the design, with greater window openings on the southern side, opening to views over Pen Y Fan, and fewer openings protecting against to the harsh weather from the north. The larch cladding was felled from the client’s land two miles away and milled on site. Recycled Welsh slates wrap over the roof and down the exposed north wall. Internally, the plan is strictly modernist along two key axes and with all the services housed in a deep north wall, including the bathrooms and stairs. A double-height central void provides a natural stack for hot air from the stove and solar gains to distribute to the upper floors. The house is exceedingly green, with an emission rate of a mere 6kg/CO2 per year.
