Goldman Sachs backs Quantum Development Finance with SME housebuilding facility worth up to £500m
SME housebuilding lender, Quantum Development Finance (Quantum), has secured a long-term facility worth up to £500m 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 £200m up to £700m.
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 £35m, Quantum has financed the development of 4,000 new homes to date and hit its £1bn 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.
Rob Sinclair, principal, AB CarVal: “We’ve supported Quantum Development Finance since day one, and this expanded facility represents an important next step in the platform’s growth. Quantum has built a differentiated lending model around deep borrower relationships, disciplined underwriting and the ability to flexibly support clients with agility across the lifecycle of projects. The quality of Quantum’s existing loan book is high and the fact that 80% of their borrowers are repeat or direct clients stands out. The expanded funding and product set should allow the team to build on that model and even better serve the needs of UK property developers and investors.”
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.”
Quantum was established by Oliver Thompson, CEO, Rebecca Murphy, COO and Chris Proud, CFO, three property development finance professionals with over 50 years’ lending experience between them. Oliver and Chris first worked together at Titlestone where they spent a cumulative ten years until its acquisition by Paragon in 2018.
The founders have since built a team of the industry’s best, including Richard Hemmings, MD who joined Quantum after 19 years at Close Brothers, Chris Dunton, credit director from UTB and Sam Hudson, head of portfolio management from Pluto.
Expanding the scope of what they can lend against was a natural next step for the Quantum team. Thompson: “Broadening our product range to accommodate customers from acquisition to post-completion has always been a key part of our growth strategy and one that complements the deep relationships we have built with our clients over several years. At Quantum we’re focused on designing a lending business with our borrowers in mind. The foundations are now in place for the next phase of our fast and sustainable growth plan.”
