Project in Focus: Tanners Hill

Posted on Monday, December 11th, 2017

Tanners Hill is a residential development located in the prime South East London location of Deptford within close proximity to New Cross and Deptford train stations. The former industrial site that had previously been unused for almost 15 years was acquired and transformed into 58 modern one, two and three bedroom apartments. CGL Facades were appointed to manufacture and install the feature façade panels around the balconies of the building.
