A Grand Sweep in Plain White Quartz
Some materials make their statement through colour and pattern. Others do it through form. This staircase, clad entirely in plain white quartz, is very much the latter; a sweeping, curved structure that commands the entrance hall of this new build property in Beaconsfield through sheer elegance of line and the quality of its finish.
Coulon Stone was brought in by the developer to clad a newly constructed concrete staircase structure from top to bottom, turning a raw shell into the defining feature of the home.
The Material
Plain white quartz was specified for its clean, consistent finish and its ability to hold a precise edge across complex geometry. Where natural stone would introduce variation, quartz delivers uniformity; here, that uniformity is exactly what the design required. Every curve, every tread, every riser reads as part of a single, continuous form.
The Work
The scope covered every visible element of the staircase: treads, risers, the string course running the full length of the flight, curved and faceted sections at the base, and a curved landing detail at the top, hung from above and finished with equal precision. The underside of the staircase was left to plaster, with Coulon Stone responsible for all the exposed stonework throughout. Each component was fabricated in the workshop and installed onto the existing concrete structure, which was clad entirely and left with no trace of what lay beneath.
The Challenge
The string course was the most demanding element of the project. It has to be geometrically perfect; the treads and risers sit directly on top of it, and the angle of each step is determined by how accurately the string course has been set. A single millimetre of error compounds through every step above it. The curved sections at the base and the hanging detail at the top added further complexity, each requiring careful fabrication and precise fitting to achieve the seamless result visible in the finished staircase.
The ResultThe finished staircase has the grandeur appropriate to a property at this level. The plain white quartz gives it a sculptural quality; clean, confident, and beautifully resolved. For the developer, it became an immediate selling point; the kind of feature that stops a viewing in its tracks before a word has been said about the rest of the house.
From templating to completed installation, the full project took about 3 weeks.
