Located in the heart of St James’s, 23 King Street provides over 45,000 sq ft of premium Grade A office space over ground and six upper floors. Standard Life Investments appointed Trehearne Architects to transform a dated office building into a high-quality central London HQ, to stand alongside nearby buildings housing companies such as BP and HSBC Private Bank.
Trehearne set out to produce a ‘new’ building, by reconfiguring the property’s internal layout and maximising leasable space. An additional floor was created within former plant room space at roof level, to create seven storeys of high specification office space and an additional 34% of lettable accommodation. The building has been partially pre-let to Temasek, the Singaporean Sovereign Wealth Fund.
