London Office Shortage Stalls BlackRock Expansion Plans

With over 3,000 employees in London, BlackRock is facing a major office space crisis and is unable to find a single building big enough to house its growing workforce in the heart of the city.

The City of London is facing a significant office space shortfall as global investment firms ramp up operations and seek larger, more sophisticated headquarters.

BlackRock, the world’s largest asset manager, is one of the most prominent examples of this growing mismatch between demand and supply. With its London workforce now exceeding 3,000, the firm has found it increasingly difficult to secure a single, modern office building capable of housing all employees under one roof.

Despite its base at a 13-storey tower in Drapers Gardens, close to the Bank of England, BlackRock has found existing options in central London inadequate for its long-term expansion.

The firm has ruled out relocating to Canary Wharf and remains frustrated by the lack of scalable, high-quality office developments in the heart of the financial district, according to The Times.

BlackRock’s recent acquisitions — including Global Infrastructure Partners and Preqin — and its ongoing push to acquire private credit firm HPS have only intensified the need for a more expansive headquarters.

However, London’s real estate market is currently constrained, particularly in delivering the type of large, sustainable, and prestigious office spaces sought by multinational firms.

Developers have struggled to keep pace with corporate requirements. Many paused construction projects during the pandemic due to cost inflation and market unpredictability, leaving a pipeline that fails to meet the expectations of large tenants.

As a result, newly built and refurbished office space is being snapped up quickly: CBRE estimates that 46% of current developments are already leased.

Tenants are also becoming more selective. Despite increased flexibility in working arrangements, many employers are actively seeking high-end, environmentally certified buildings to draw employees back and align with ESG targets.

The result is heightened competition for top-tier space and a surge in lease rates. Prime office rents in the City have jumped 9.1% over the past year, with several recent deals exceeding £100 per square foot annually, which is an uncommon benchmark just a few years ago.

Securing space large enough for BlackRock’s needs appears especially difficult. Accommodating more than 3,000 employees would require over 350,000 square feet, which is more than two-thirds of the floor space of the Gherkin. At present, only one building in central London under development (50 Fenchurch Street) offers that level of capacity, and remains unclaimed.

While BlackRock is not currently planning to leave Drapers Gardens, where it holds a lease extending more than a decade into the future, its predicament underscores London’s growing challenge. Without more substantial investment in large-scale, state-of-the-art offices, the City risks ceding ground to other global finance hubs better equipped to support institutional expansion.
