What type of projects does Janine Stone take on?

Janine Stone works exclusively on luxury private residential projects including complete new builds, major renovations, listed building restorations, extensions, basement developments, and interior design commissions ranging from single rooms to whole-house projects.

Where does Janine Stone work?

The majority of projects are in London — particularly Belgravia, Mayfair, Kensington, Chelsea and Knightsbridge — and the Home Counties, but the firm regularly undertakes projects across the UK and internationally.

Can I hire Janine Stone for interior design only without architecture?

Yes. Each service — interior design, architecture and construction management — is available as a stand-alone service or as part of the integrated concept to completion offering.

How do I start a project with Janine Stone?

Contact the firm via telephone on +44 (0)20 7349 8888 or email enquiries@janinestone.com to arrange an initial consultation. There is no obligation at this stage.

What is the Clarity pre-purchase assessment?

Clarity is an independent property assessment designed for the luxury residential market. Before a buyer commits to purchasing a property, Clarity provides expert evaluation of design potential, structural condition, true cost of renovation, and planning feasibility — providing buyers with actionable intelligence about what a property could become, not just its current condition.

Our Story

A dedication to
exquisite homes

What began over thirty years ago as a passion for creating beautiful interiors has grown into a multi-disciplinary practice encompassing architecture, interior design and construction management — three disciplines united under one roof by a shared conviction: that exceptional homes demand exceptional care at every stage.

We have earned the trust of the most discerning clients by treating every project — from a London townhouse to a country estate — with the same meticulous attention to detail. No compromise, no shortcut, no detail too small to consider. See more of our work as interior designers in London.
