Conversion Specialist in Marylebone, North London
Renovations & Alterations Design & Build. With 22 years of experience as a fully qualified electrician and 7 years specializing in kitchen fittings and carpentry, I have honed a versatile skill set that allows me to tackle any challenge. My recent tenure with Purdy & Figg has seen me construct and electrify a variety of spaces, including offices, laboratories, media rooms, and restrooms. In addition to this, I craft custom-designed summer houses, porches and i also do fencing. As a hobby, I also take joy in building custom campervans. I take immense pride in my work, ensuring that every project is seen through from start to finish with the utmost attention to detail, which I believe is the cornerstone of a job well done.

Electrical- 4 Jun 2025
The job went very well. An Envirovent 150 fan was installed with a separate thermostat and isolator switch, together with two 150 mm diameter inlet vents. It had to fit into a tight space, which took some care and careful fitting, but the result was perfect. Rob and Harvey are pleasant and diligent workers.

Hi! Platinum Build is a small main contractor based in Essex. Working as a project manager for many years, Platinum Build was set up in the summer of 2021 in order to provide cost effective building quality that the industry is currently lacking! With an already robust proven track record, works predominantly undertaken include domestic and commercial fit-outs/refurbishment. No job too big or small. Thank you. Nick.

Conversions - General- 21 Apr 2022
We are a large primary school in Barking and needed some additional offices built for 3 members of staff. Platinum build successfully quoted us for the build and carried out the works in the school holiday. Platinum Build took control from the idea stage right through to completion, and carried out the works professionally and to a high standard of workmanship. All tradesmen were efficient, and on completion brought in there own cleaning company to ensure the areas were left clean and tidy. The finish has blended in nicely with our current decor and everyone is happy with the work. I can strongly recommend Platinum Build. We will certainly use them for future work. Thank you very much Nick.
