SME housebuilding lender, Quantum Development Finance (Quantum), has secured a long-term facility worth up to £500 million from Goldman Sachs, as it prepares to fund a wider range of schemes across their entire lifecycle – from initial acquisition through to post-completion investment facilities. This deal marks an expansion of its funding from £200 million up to £700 million.

This additional facility significantly expands Quantum’s lending capacity, including the ability to support larger loan sizes, without changing the business’s focus on SME housebuilders. The new funding will be used to support schemes in Quantum’s new and existing customer pipelines.

Founded in London in 2023, Quantum has fast become an established provider of development and bridging finance to proven, quality SME housebuilders in cities and suburbs throughout England and Wales wherever there is an urgent need for high quality new homes.

Funds managed by AB CarVal, a global alternative investment manager with longstanding experience in asset-based finance and part of AllianceBernstein’s Private Alternatives business, have backed Quantum since its inception in 2023. As both a shareholder and primary funding partner, AB CarVal has supported Quantum’s growth from its first loan through the continued expansion of its lending platform.

In the last 12 months, Quantum has expanded its product set for operational real estate including Build-to-Rent, PBSA and Co-living. For new and existing borrowers, this covers development and post-completion stabilisation and investment lending. This expansion has been particularly helpful for existing borrowers who wish to seamlessly switch their current development finance loans to longer-term facilities upon practical completion, benefiting from a single relationship route all the way from delivery through to stabilised income.

Providing loans up to £35 million, Quantum has financed the development of 4,000 new homes to date and hit its £1 billion funding milestone during Summer 2026. Quantum’s Bermondsey-based team of 16 has 125 live projects ranging from acquisition loans to five-year operational real estate facilities.

Oliver Thompson, Co-Founder & CEO of Quantum Development Finance: “Goldman Sachs’ approval of this facility is a positive signal for the Quantum team as we focus on building an alternative credit platform with bank-level operational rigour. It’s also a huge endorsement of the team we’ve built and the discipline we bring to every deal and operational running of the business. For our clients and partners, these large and long-term commitments from established funding partners, Goldman Sachs and AB CarVal, are a clear signal that Quantum has the appetite and readiness to keep backing high-quality developers and property investors, at every stage of their journey – whether that is their first scheme with us, or their fifth.”
