Refurbishment Contractors

We are an experienced refurbishment contractor working across London and the home counties. For more than 40 years, we have been working with our clients to deliver refurbishments of all sizes and across sectors, including healthcare, commercial, social housing and education.

Our team has the expertise and experience to deliver large scale refurbishments, fit outs, repairs, internal and external decoration, window replacement, mechanical and electrical services, and fire door installations.

We have built long-standing working relationships with many of our clients thanks to our specialist skills, collaborative approach and strong reputation as a high-quality refurbishment contractor in London.

Our Skills

In partnership with our clients, we deliver a vast range of refurbishment projects.

In the healthcare sector, the quality of our work has enabled us to forge strong partnerships with several of London’s NHS Foundation Trusts. Our experienced team has a proactive, responsive, and flexible approach that minimises disruption for patients and staff.

Our expertise in the public sector has also seen us deliver commercial projects, including office refurbishment, as well as upgrades and improvements to public buildings such as fire stations, police stations, town halls and libraries.

For the education sector, we have a proven track record in refurbishing and remodelling schools, academies, colleges and universities, including Special Educational Needs and Disability (SEND) facilities.

Refurbishment contractors must be skilled at working in live, operational buildings. To minimise disruption, we liaise closely with our clients from the outset, agreeing logistic plans and work programmes that are effectively communicated to all relevant parties. All our refurbishment work is meticulously planned, ensuring we deliver high quality developments to the safest standards possible.

Our Projects

Diamond Build PLC specialises in refurbishment and new build projects ranging from £2m – £20m. Diamond Special Works carries out refurbishment, repairs and building maintenance for projects up to £2m.

Diamond Fire Safety works with local authorities and housing associations to ensure their buildings meets the latest fire safety standards.

Examples of Diamond Build PLC’s projects include an office refurbishment for Islington Council. Constructed in the late 1950s for office use, 49 – 59 Old Street was formerly home to the Post Office and spans seven storeys plus a basement.

Islington Council appointed Diamond Build PLC to refurbish the property into high-specification office space to maximise the building’s rental potential. The brick facing façade was repaired and the interior reconfigured and refurbished to provide a total of 18,823 sq. ft. of office space.

The project also included the construction of two new roof terraces on the first floor. A further roof terrace was created at the top of the building requiring the construction of a new dedicated lift, staircase and kitchen area.

Diamond Build PLC was also selected by Islington Council to partially refurbish three floors of Finsbury Library. The refurbishment included new timber panelling, lighting and redecoration, resulting in a clean, light and welcoming public building.

The refurbishment of an industrial facility in London, carried out by Diamond Special Works, was recognised at the London LABC Building Excellence Awards. The Tailoring Academy at Finsbury Park was crowned Best Small Commercial Project at the awards, which praise building excellence and the people who go the extra mile to deliver their work.

Diamond Special Works was responsible for transforming the ground floor of an existing warehouse into the new contemporary space, which features a folded timber and glass screen that surrounds pockets of workspace. The refurbishment comprised exterior and interior work, including installing new heating and partition walls.
