Grosvenor Provides £53.5 Million Loan to Beltane Asset Management and TPG Angelo Gordon for Belgravia Office Redevelopment

Grosvenor's UK lending business has closed a £53.5 million loan to Beltane Asset Management and TPG Angelo Gordon to finance the acquisition and redevelopment of One Chester Street, an office building in Belgravia, the firm announced July 23, 2026.

The transaction is the largest loan completed to date under Grosvenor's UK property lending strategy, which the firm launched in 2022 to provide flexible financing to experienced sponsors across the real estate lifecycle, including ground-up development, refurbishment, repositioning, and asset enhancement projects throughout the United Kingdom.

Deal Structure and Asset Details

The three-year facility will support an extensive refurbishment programme at One Chester Street, a roughly 50,000-square-foot building situated on the corner of Chester Street and Grosvenor Place in Belgravia. The property benefits from dual frontage and proximity to Mayfair, St. James's, and Knightsbridge — among London's most prestigious West End office locations.

The planned redevelopment is designed to reposition the asset as a high-quality, sustainable office destination. Work is expected to deliver Grade A office space with private terraces and views, while enhancing the building's sustainability credentials. Financial terms beyond the loan amount and tenor were not disclosed.

Belgravia's planning sensitivity and conservation constraints severely limit new office development in the area, making comprehensive refurbishments of existing buildings one of the primary mechanisms for creating modern, ESG-compliant space in the submarket. Demand for best-in-class offices in the area is driven by family offices, boutique asset managers, private equity firms, and high-margin professional services tenants seeking proximity to Mayfair and Knightsbridge.

Grosvenor's Lending Strategy and Market Positioning

Grosvenor's UK lending business operates from the firm's own balance sheet, combining long-term capital with in-house real estate expertise to underwrite complex development, refurbishment, and repositioning opportunities. Over the next decade, Grosvenor aims to deploy approximately £1 billion through the lending platform, targeting projects that deliver commercial returns, increase housing and office supply, and contribute to the decarbonisation of the built environment.

Steph Ball, Executive Director for Investment at Grosvenor Property UK, said the transaction reflects the type of opportunity the lending business is designed to support.

"One Chester Street reflects the type of opportunity we look to support through our lending business: a well-located asset with strong underlying fundamentals, backed by experienced sponsors and a clear strategy to create long-term value. We are pleased to be supporting Beltane and TPG Angelo Gordon as they reposition the asset for its next phase.

"Many of today's most compelling opportunities lie in reimagining well-located buildings, and supporting the refurbishment of existing assets is an important part of the transition towards a more sustainable built environment. By providing flexible financing solutions, we can help sponsors deliver higher-quality, lower-carbon space while preserving and enhancing some of London's most distinctive commercial buildings."

The loan reflects a broader trend in which large, long-term landlords and estate owners are stepping into the lender role to shape submarket outcomes, particularly as traditional bank lenders have remained cautious on office exposure — especially for non-ESG or sub-prime stock — in a higher interest rate environment. Non-bank and institutional lenders have moved to fill that gap on prime refurbishment schemes where the underlying risk profile is more clearly underwritten.

Sponsor Perspective

Duncan Roe, Partner at Beltane Asset Management, described the acquisition as a strategic portfolio addition.

"One Chester Street represents a strategic addition to our portfolio. The planned refurbishment will reposition this asset to meet current occupier requirements whilst respecting the architectural heritage of this prestigious Belgravia address."

West End Office Market Context

London's West End office market has been defined in recent years by a pronounced flight to quality, with occupiers prioritising modern, energy-efficient space over older stock. That dynamic has supported the business case for capital-intensive refurbishments in prime locations, where top-quartile offices have maintained comparatively resilient rents. Belgravia, in particular, faces supply constraints that make projects like One Chester Street among the few viable routes to delivering new Grade A inventory in the submarket.

Grosvenor, which has deep roots as an estate-based owner and developer in Belgravia and Mayfair, has publicly committed to substantial carbon reductions across its portfolio and has been actively financing and supporting retrofits of older buildings to meet net-zero and energy performance requirements. The One Chester Street loan aligns with that strategy, channelling capital toward refurbishment and adaptive reuse in a conservation-sensitive area where new construction is rarely feasible.
