Refurbishment and conversion of two Grade II listed stone buildings into luxury apartments situated upon Bristol harbour.

Architectural Stone were contracted by Speller Metcalfe to assist with the renovation of Bristol’s harbourside.

The site is home to the historic Purifier House and the Engine House, which are the last gas works buildings renovated on the harbourside. The buildings were developed into 58 modern homes, formed of one, two and three bedroom apartments.

Having sat derelict for over 40 years, this restoration project marks the final pieces of the regeneration of the city’s floating harbour.


Our team were brought in to carry out enabling works on the site for construction to safely take place. The first part of this task was to enable easy access to the buildings, which required our workers to create a hole in the exterior stone wall of the site.

Due to the Grade II listing of the buildings and the grounds, the face work stone from the wall needed to be carefully recorded and stored, ready to be rebuilt at a later date.

We then secured the building with large steel supports, which wrapped around the exterior to ensure the safety of the workers. The project then involved taking down coping stones, taking down one of the gable ends and removing loose stonework from the top of the building prior to the construction team working on the site. We made a record of all of the removed stonework, put into storage and then reinstated into the restoration of the building.

A history

Brandon Yard has been built upon the Canon’s Marsh gasworks site, once flourishing with industrial endeavour it has languished alongside Bristol’s disused waterways derelict for over 50 years. The site now serves as a pinnacle of luxury accommodation in the city.

It was in the mid 19th century that Bristol saw the arrival of its floating harbour, then packed with factory buildings fed by the freight of the endless string of ships jostling for space in the harbour.


Originally a timber yard, the growing popularity of gas lighting in Britain saw the development of buildings built solely for gas production. This saw the emergence of the two buildings standing at Brandon Yard today; Purifier House that took care of purifying the gas before Engine House equipped with its boilers and steam engine pumped it into the city’s pipe network.


Both buildings’ construction is from Pennant stone with a detached brick chimney, a detail that now serves as the central feature of the new development. The boundary wall, as it suggests served as a safeguard from coal thieves. Both the buildings and the boundary wall are grade II listed.


A grand assignment for Architectural Stone, we are proud to see this historical site breath a new life into the city again.
