• 47 Belgrave Square, London

    The centre of London is home to some of the most expensive real estate in the world, termed ‘Super-Prime’ properties. Comprising 12 bedrooms, 2 basements, 2 lifts, a cinema, a gym, separate leisure areas, a 20-metre swimming pool, plus a separate mews property, this Super-Prime project totaled 22,500 sq. ft. Darke & Taylor was one of a number of subcontractors working on this project, which required flexibility, teamwork, and an exacting approach to quality control.

Let there be light? This was a complex brief, with the client specifying a light and airy feel throughout, whilst setting numerous technical challenges, such as a pool which could drain itself and turn into a dance floor?

Super-prime, Grade I-listed: A house of this size required Darke & Taylor (D&T) to work alongside many other contractors, yet within the confines of a listed building. This meant working with non-construction professionals, such as interior designers, for whom the aesthetics were key, rather than the engineering protocols.

It’s all about the finish: There were a number of original bespoke lighting pieces commissioned for this property. These all had to be assembled and installed by D&T, with no two the same, and each costing many thousands of pounds – there was no room whatsoever for any mistakes!


Bringing the outside in: What looked like an idyllic outside patio was, in fact, an underground basement. Over 1,000 LED lights, each with 6 diodes and underpinned by a complex DMX programme, allowed features such as an ever-changing cloudy sky to be programmed into the ‘pool ceiling’, giving the illusion of being outdoors.

Problem-solving mindset: D&T prides itself on working towards the client’s end vision and being part of the solution. This required a significant amount of compromise, for example, working with wooden beams rather than RSJ’s and ensuring that all original features stayed in place.

A joint effort: Meticulous planning, expertise and a good working relationship with the builders, ensured that D&T could foresee potential issues early on. For example, the chandelier weighed almost half a tonne and required a strengthened ceiling, which D&T was able to specify early on in the rebuild process.


“We are very pleased with how the programming went, this has been a complex design and installation process with a lot of interface, and we really appreciate the first-class coordination and input from the various contractors and consultants.”
