Sigma Capital Group has announced the acquisition of four new development sites worth around £100 million in gross development cost (GDC), continuing its strategic partnership with Vistry Group.

The projects will deliver 415 new single-family rental homes across England, further cementing Sigma's role as a leading player in the build-to-rent sector.

The four sites include:

• Top Wighay Farm, East Midlands – 153 homes

• Ibstock, St. Helens, North West – 120 homes

• Sutton Road, Maidstone, South East – 87 homes

• Womersley Road, Knottingley, Yorkshire – 55 homes

All homes will be built by Vistry Group and, once completed, will be owned and managed by Sigma Capital, with the company's in-house Simple Life team overseeing leasing and tenant services.

This acquisition brings Sigma's total balance sheet investment to £1.06 billion, encompassing 4,510 homes. Sigma now operates nationally, managing rental properties from central Scotland to southern England and London.

These new developments come as Sigma continues a year of accelerated growth. The company has completed around 2,500 homes to date in 2025, with the number expected to rise to over 3,800 by year-end. Upon completion, the portfolio will generate an estimated £77 million in annual rent.

Across all its investment partnerships, Sigma has now delivered over 13,500 new homes, of which 10,600 are completed, with the remainder under construction. The total estimated rental value (ERV) of these homes exceeds £190 million per year.

Graham Barnet, CEO of Sigma Capital, said: "We recently celebrated a decade in single-family build-to-rent and this latest round of acquisitions shows that we are still consistently innovating and adding to our growing portfolio.

"With these four new sites, we're not only expanding our footprint across key regions, but also enhancing the quality of the homes we deliver, working with our trusted partners. Our current pipeline of opportunity now sits at over £5bn GDC throughout the UK, confirming our position as the leading single-family housing provider in the country.

"As demand for high-quality family rental housing continues to grow, we’re proud to play a leading role in supporting housing delivery, offering a professionally managed, secure solution for our customers."

Stephen Teagle, Chief Executive of Partnerships and Regeneration at Vistry Group, added: "We're delighted to see this further extension of our long-standing partnership with Sigma Capital to deliver high-quality, professionally managed rental homes across the UK. These new developments reflect our shared commitment to accelerating housing delivery through diverse tenures, meeting local needs, and supporting the Government’s housing ambitions. Together, we're creating thriving professionally managed communities with homes people are proud to live in."
