Moments from the centre of the City, bordered by dual carriageways and a substantial roundabout, sits a most remarkable building.
What is it?
It’s almost unfathomable.
A carpark lacking entrance and exit, abattoir, contemporary art space?
No – an electrical substation, on such a colossal scale as to relieve you temporarily, of a gasp or two.
Finished entirely in unfinished concrete, a great volume, broken by vertical and horizontal lines, punctuated by intermittent abutments.
Accessed externally via a most extraordinary glazed and enclosed staircase.
Wisely Historic England have had the site listed:

“Electricity substation. 1968 to designs by consulting architects Jefferson, Sheard and Partners, Sheffield, led by Bryan Jefferson, in association with the Regional Civil Engineers’ Department of the CEGB North East Region. Contractors, Longden & Sons Ltd, Sheffield. Reinforced concrete frame with board-marked finish with formwork bolt marks, construction and daywork joints emphasized, concrete floor slabs, blue engineering facing bricks, cladding panels of Cornish granite aggregate.”
Go see for yourself, if you don’t believe my eyes.
