Part of the Blockstone group with blocks available from the Block Store at Cadeby Quarry as well as from Neston. Top Bed was one of the best quality Bath Stones until Park Lane closed in 1960. Re-opened in 2013, the uniform cream-coloured stone with occasional veins and shell is once again available.

From the initial freeze-thaw process that enables the stone to be riven into thin sheets for roofing, to the chipping and dressing of each unique slate ready for installation, Collyweston roofing slate production is an art of its own even before the slate is laid on a roof.
