Reinforced concrete slab sitting on the existing conservatory foundations.
Due to the tight access with this site we had the concrete pumped in.
For this build we used 11mm OSB board both externally and internally.
We find this increses the strength of the wall, especially against knocks.
We upgraded to a more thermally efficent space.
The building is clad in 'Marely Cedral Click' board, EPDM roof with a triple glazed flat lantern.
