Project: Middlesex Street Estate

Client: City of London Corporation

Barwin was commissioned by the City of London Corporation to carry out essential concrete testing on the Middlesex Street Estate.

Located next to the iconic Gherkin in the heart of the City, this estate holds significant historical value. Built between 1965 and 1970 on a site devastated by WWII bombing, it was one of the largest inner-city redevelopment projects undertaken by a public authority in post-war Britain. The estate features the 23-storey Petticoat Tower and low-rise buildings around Petticoat Square, all constructed using concrete and engineered brick.

With approximately 10,000 m² of concrete to assess across the estate’s 234 dwellings, this testing will be crucial for developing a technically robust specification for a long-lasting, durable repair system. The goal is to ensure this historic estate remains safe, sustainable, and updated for generations to come.

Scope of works:
