Northumberland Buff

Medium grained honey/buff sandstone.

Quarried near Otterburn, Northumberland, this Honey coloured stone is fine grained, with a striped pattern running through it. Northumberland Buff is taken from the top seem of Blaxter quarry, which has been operated since the late 1800’s. This stone has been used for many key buildings, mainly in Newcastle, such as the Theatre Royal. More recently it has been used on Princes Street Edinburgh, for an infill development, and the Stephenson Quarter Development, behind the train station, Newcastle, which includes a Crown Plaza Hotel.
