An exceptional blend of modern meets traditional

Excellent natural light and a unique working environment.

Occupying one of the most prominent sites on Clerkenwell Road, Cornwell House was built by the Victorian developer Charles Powell in 1880 as the Sessions House Hotel. It was later converted into a spectacle factory and offices for the General Optical Company and renamed Cornwell House after which it was refitted as craft workshops.

The building has been extensively redeveloped behind its sweeping façade, designed by EMRYS Architects. The Lower Ground and Ground floors provide retail / showroom space of 1,772 sq ft with a distinguished shop frontage wrapping around Clerkenwell Road and Clerkenwell Green.

The office floors benefit from the unique curved form of the building and large sash windows providing excellent natural light and a unique working environment.

A new floor has been added with a feature zinc clad roof and roof terrace with exceptional South and West facing views of central London.
