The Best Little Townhouse in BELGRAVIA

Patience is, of course, a virtue. Don't believe us? Just ask designer Markham Roberts, who spent four years working on this once-in-a-lifetime house in London.

In our age of instant gratification, rapid-fire renovations are the norm. That's what makes what New York-based interior designer Markham Roberts has achieved in a 19th-century Georgian-style Belgravia mansion-one of London's largest private residences-so extraordinary. Over four years of working on a house so grand it could easily be mistaken for an embassy, Roberts orchestrated what can only be described as a master class in slow design, where age old craftsmanship meets modern living and where every detail has been given time to reach its full potential.

To execute his vision, Roberts enlisted the architectural firm Bories & Shearron, whose meticulous design drawings and understanding of classical proportions proved invaluable in guiding the local teams through this complex transformation. The result is a tour de force of the decorative arts, from handrolled glass to horn-flecked plaster with bronze banding, and a house in which each room tells its own story and also contributes to a greater narrative.

That this Grade II-listed, 13,500-square-foot architectural gem has become a deeply personal family home rather than a museum speaks to Roberts's genius for balancing grandeur and intimacy. With clients who understand that excellence cannot be rushed, he has created something that defies the contemporary appetite for quick solutions: a home where every detail has been considered, each finish perfected, where the passage of time has been an ally rather than an adversary. Here, T&C and Roberts discuss the remarkable transformation.

T&C: Four years is quite a commitment for any project. What made this extensive time frame not just preferable but vital to achieving the result?

MARKHAM ROBERTS: The house was a seductive siren of a potential project. Even if someone had told me it was going to be a 10-year project, I'd have still pushed people out of the way to jump at it.
