Purpose-built rental accommodation — known as build-to-rent (BTR) — has grown from occupying a niche corner of the residential market to becoming an increasingly common feature in towns and cities across the UK. At 237,000 homes, there are now almost a quarter of a million BTR homes across the UK that are either completed (73,739), under construction (47,464) or in planning (115,859), according to the British Property Federation (BPF). Over the past year, there has been a 44 per cent increase in the number of units in planning, making it the country’s fastest-growing housing sub-sector. For this cost model, we will be looking at a regional BTR development in the Home Counties.
