Rosliston Forestry Centre was created on 90 ha of former farmland in the Mease Lowlands. It is owned jointly by South Derbyshire District Council and Forest Enterprise and provides a shop, restaurant, indoor play area and craft centre. The site offers a range of outdoor activities such as walking, cycling and outdoor play areas.

The Forestry Commission were keen that their building should be made from British timber. Due to the large spans of the proposed building, the hollow high structural capacity Tŷ Unnos box section portal frames offered a highly efficient homegrown timber solution.

Pitched portal frames are set at 5m centres and the longest span is 8175mm overall. Each is tapered, from 500mm deep at the haunch tapering to 350 mm at the apex and 400mm at the base. This provides 5 workshops. Where exposed internally, the structure is coated with Envirograf to control flamespread.

The timber frame is infilled with prefabricated wall and roof panels using C16 timber, sourced from Pontrilas Timber.
