In our Grade II listed Mayfair duplex at 1 Carlos Place, every element was designed and made bespoke — joinery, furniture, curtains, even the bed covers. The only thing we bought ready-made was the lighting. This is what that buys you, and when it isn't worth it.

A curtain maker will make what you ask for, beautifully. The harder question is what to ask for. Fabric, border, pole, heading, sheer — five decisions sit behind every window in a prime London home, and getting one of them wrong is why a finished room still feels off.

Most of our clients have done this before. They have had several homes designed, and more than one has been disappointed by the studio they chose. This is the standard an experienced client is entitled to expect at every stage of a prime London refurbishment — and where previous designers tend to let them down.

Adding a storey to an existing London building sounds straightforward on paper. In a conservation area, it's rarely that simple. A note on the planning conversation, the design constraints, and the year of invisible work that usually comes before a single wall is built.

Not every client can give a project two years of close personal attention. Developers and overseas owners often need a studio they can trust to carry the work themselves — from concept through site to final styling. A note on how we operate when that's the brief.

It comes down to how the marble was chosen. Here are the five mistakes that turn six-figure stone budgets into expensive regrets — and how we avoid them at Supremati.
