It was once the jewel in Stockton-on-Tees’ crown - an aspirational address where the well-heeled middle classes built their lives in proud red-brick Victorian homes.

But today, Hartington Street stands as a haunting shadow of its former self and a sobering symbol of Britain’s urban decline.

Crippled by crime, ravaged by drug abuse, and hollowed out by absentee landlords, the street is now a grim patchwork of HMOs, halfway houses and temporary accommodation.

Nowhere is that downfall more visible than at No. 15.

Once a grand, three-storey family home, it sold for £300,000 in 2014. Just eight years later, it was snapped up for just £90,000 - a 70% drop in value.
