Listed Building Refurbishment and Construction
Operating across London and the home counties, we have extensive experience of listed building refurbishment. Working with local authorities, we have the expertise to upgrade historic buildings and heritage assets, ensuring listed buildings are sensitively restored.
We have built long-standing working relationships with many of our clients thanks to our specialist skills, collaborative approach and strong reputation in listed building refurbishment.
Our Skills
Listed building refurbishment requires main contractors to have specialist skills and knowledge to not only meet the client’s needs, but the demands of key stakeholders, including Historic England, the local conservation officer and local planning authority.
Our extensive experience means we understand the challenges of listed building refurbishment and how to liaise effectively with key stakeholders to deliver the brief. We ensure that any queries or concerns are addressed quickly and effectively throughout the process, and can combine modern and traditional construction methods to meet all requirements.
Our Projects
Our expertise in listed building refurbishment has seen us deliver a wide range of projects for local authorities across London and the wider area. One example is Islington Council which appointed Diamond Build PLC to sympathetically refurbish an assembly hall, situated adjacent to the town hall.
Disused for almost three decades, the Grade II listed building had fallen into disrepair. Working closely with English Heritage, the council wanted to breathe new life back into the space creating a facility for community and corporate events in the bustling north London borough.
Oak panelling, which features throughout the auditorium, was retained by Diamond Build PLC and restored to its original condition. The existing ironmongery and light fittings were also retained, and the foyer restored using original materials and colours. On the first floor, gallery seating was upholstered in the original colours. The surrounding walls, floors and ceilings were also refurbished in materials and colours to match the existing.
Services were upgraded while protecting the fabric of the building. Sections of oak panelling were adapted, enabling access to the voids behind them, which were used to house sockets, preventing them from being visible. The existing ventilation system was also modified to bring it up to the required standards and period-style column radiators installed around the perimeter of the space.
Our team was also responsible for constructing a new lift into the foyer. To minimise the impact from a design perspective, the lift and its enclosure were made from glass, so the structure is completely transparent.
Another example of our listed building refurbishment expertise can be seen at Hogarth’s House in Hounslow, which was built between 1715 and 1719. The project’s aim was to create a new and accessible studio space for hosting community events, seasonal activities and learning programmes, and to re-landscape the garden to highlight historic planting and themes.
Diamond Build PLC was responsible for constructing a new single-storey studio, which was subtly connected to the existing house. The ground floor of an existing kitchen was altered to accommodate the new building and a new reception area, corridor and disabled toilet constructed.
As part of the project, an historic Grade I listed garden wall was repaired and restored by our team and an exhibition garden was created, presenting aspects of the site’s history. New paths were laid, and a frame installed over the ‘nut walk’ to the new studio, incorporating serpentine bars and iron mulberry leaves.
The site’s limited access meant that effective sequencing was crucial throughout the works. The majority of the scheme had to be completed before the landscaping could begin, and for the first part of the project, the House remained open to the public.
Diamond Build worked closely with the architects to help co-ordinate and manage the complex design, which featured a variety of components, finishes and building materials that had to be carefully integrated.

Hogarth House
Hounslow Council & William Hogarth Trust
Funded by the National Lottery Heritage Fund, the Mulberry Garden Project was a joint initiative between Hounslow Council, which is the trustee of Hogarth’ House, and the William Hogarth Trust. The aim was to create a new and accessible studio space for hosting community events, seasonal activities and learning programmes, and to re-landscape the garden to highlight historic planting and themes.
