Some brilliant progress pictures of The Stage in Shoreditch which is a £750m mixed-use development in Shoreditch on the site of Shakespeare’s former Curtain Theatre. The development will consist of a 37 storey tower, shops, restaurants and office buildings. There will be 275,000 sq. ft of office space, 412 apartments for private sale and 400,000 sq. ft of mixed use space.

O’Reilly Concrete are supplying the specifically designed 85N self-compacting concrete. The increased strength of this concrete is achieved using micro-silica which is adding to the recipe during the batching process. This unique recipe produces an extremely high standard of finish.This increased strength is due to the building being one of the tallest, multi-story buildings in the heart of London.

O’Reilly Concrete are extremely proud to manufacture and design the precast concrete columns for this high-profile and prestigious job. We are also thrilled to be working with O’Shea who are one of the largest privately-owned construction and property development companies in London and the South East.
