Helmet Row, Clerkenwell

Conversion and extension of two Grade II listed Georgian houses.

Creating additional spaces whilst respecting the listed buildings

These two inner city Grade II listed Georgian houses are located opposite St. Luke’s Church, one of Sir Nicholas Hawksmoor’s finest churches, on Old Street.

The client’s requirements for additional living accommodation within their original house was achieved by an extension across the rear gardens of both houses, facing the original house across a courtyard,  providing open plan, spacious, contemporary living space while maintaining the original house and its cellular Georgian rooms for bedroom and ancillary accommodation.

The paved courtyard, enclosed by the new extension and the original house, acts as an outdoor extension of the living accommodation.

The upper floors of the second house were converted to a self contained maisonette with an office/retail unit at basement and ground floor levels.

The street façade remains unchanged.


The development is located in Clerkenwell, North London.
