Size and Capabilities
Dunhouse Quarry currently operate nine quarries in the North of England and Scotland. We quarry a wide range of stone, including buff stone from Northumberland and Durham, Scottish Red Sandstone, and Weardale self bedded paving and walling stone.
Large stock levels of block stone are maintained to ensure continuity of production.
Our factory at Staindrop is comprehensively equipped to supply bespoke masonry on any scale necessary, enabling us to take on the most challenging of jobs. For example The Scarborough Pier replacement required us to quarry 12000 tonnes of block and supply 1800m3 of masonry in twelve months.
Our Laithes and CNC machinery have turned columns and balustrade for many prestigious projects including column segments for Covent Garden and Victoria Bus Station. We have had the pleasure in supplying the intricate carving to many restoration projects, notably, Jenners refurbishment (Edinburgh) and The Scottish National Portrait Gallery (Edinburgh) both requiring large scale replacement of fine masonry.
