Trehearne Architects transform 100 Pall Mall into striking new London HQ

Trehearne Architects has delivered the dramatic transformation of historic 100 Pall Mall – with the presence to attract a blue chip tenant seeking a prestigious and prominent headquarters at a heritage address.

Destroyed in World War II when it was the former Carlton Club and rebuilt in 1959, with many unsympathetic alterations made in recent years; 100 Pall Mall has now been redesigned and refurbished by Trehearne to provide 60,000 sq ft of refurbished Grade A office space over seven floors. Most recently, the property served as the UK head office of Lloyds Bank. Standard Life Investments appointed Trehearne Architects to restore the grandeur of the past, whilst creating a blueprint for the future.

Trehearne set out to restore the building’s historic features, whilst upgrading the office floors to the highest contemporary standards. This includes the transformation of the Grade II Listed marble entrance hall with only the original fabric retained, and the restoration of a fine terrazzo and bronze staircase. Spacious new lift halls and lavatories have been added to the common areas of the building. Trehearne have also created a new unique, balconied office within a former plant room on the seventh floor, which boasts exceptional views over St James’s.

Keith Møller, a partner of Trehearne Architects and project architect for the 100 Pall Mall scheme, comments:

“From the Grade II Listed reception hall, fine hardwood windows and new granite steps, the refurbishment of 100 Pall Mall has taken two years to fully craft. We have reinvigorated every external and internal architectural detail and successfully redesigned the office space to create the ultimate work environment, which is fitting for such an elegant building. Every floor retains its fine features, combined with the most luxurious contemporary finishes.”
