The growth of single family housing (SFH) in the UK reflects a housing market increasingly shaped by affordability pressures and the need for faster, more certain delivery of new homes.
Development experts at Fisher German, Jonny Hosein (left) and Luke Brafield (right), believe the long-term success of SFH depends on housebuilders forming stronger relationships with investors to unlock the best outcomes.
Single family housing has become a core part of UK build-to-rent investment over the last few years, with 2025 being a record year for the sector. Demand for high-quality rental homes continues to rise as affordability pressures, tighter mortgage lending and changing lifestyle choices keep more households in rented accommodation for longer.
But while attention often focuses on the scale of investment flowing into the sector, there is still not enough discussion around how these schemes are actually delivered successfully, and why the relationship between investors and housebuilders is becoming one of the most important drivers of long-term value.
For many housebuilders, working with SFH investors has shifted from a short-term fix to a clear strategic choice. In our conversations with both large and small developers, the message is consistent – SFH is becoming part of the long-term business model, not a back-up plan.
The logic is simple. Slower sales, stretched affordability and the end of Help to Buy have all reduced sales momentum in many cases. By contrast, selling a tranche of homes to an institutional investor gives housebuilders the certainty they crave.
Favourable planning reform has also been a key driver. The government’s target of 1.5 million homes this parliament, alongside a more supportive stance on brownfield and ‘grey belt’ land, is widening the pool of deliverable sites. Housebuilders that can show a credible multi-tenure approach, with an SFH partner supporting delivery, are often better placed to meet planning expectations and funding requirements at the same time.
So far, the SFH market has been shaped by headline deals with major housebuilders. Those partnerships have set the tone. But if we only look at the largest players, we miss a substantial opportunity: the SME market.
Regional and SME developers often bring deep local knowledge, strong planning relationships and contractor networks. Many are actively looking to grow their SFH pipeline. They understand the value of investor partnerships and want to shape land bids and product design around investor needs from day one.
Crucially, many SME developers can deliver the scale investors require. For a lot of buyers, the sweet spot is around 70 to 100 homes per scheme: large enough deliver operational efficiencies but not so large that it creates local oversupply or creates excessive leasing risk.
The investor base is changing too. The sector has evolved from one shaped largely by private equity capital, where shorter hold periods, portfolio assembly and exit strategy often drove decision-making. Today, we are seeing more long-term institutional capital, including pension funds, looking for stable, inflation-linked income over longer hold periods.
With growing institutional demand for SFH, and housebuilders big and small treating investor partnerships as a bigger part of their model, the foundations for growth are strong.
The challenge is in execution – finding the right sites, structuring the right deals, and aligning the right partners early enough to protect value for everyone involved.
That is where having a good adviser matters to get the best deal done in good time. Having someone who can understand the differences between the pressures a regional SME housebuilder faces compared to a larger player, and how a long-term pension fund underwrites risk differently to a private equity-backed platform, is crucial.
The building blocks for investor-housebuilder collaboration in SFH are already in place, and momentum is building. The opportunity now is to raise the bar on how partnerships are formed and managed.
In practice, that means bringing investors in earlier, agreeing what ‘good’ looks like before planning, and backing delivery with clear commercial terms and a joined-up approach to design, specification and programme. Do that well, and SFH can deliver what the sector needs most – thousands of homes that people want to live in.
