Paragon Development Finance has committed £15.9 million to fund the acquisition and construction of a 35-home later living scheme in Hartley Wintney, Hampshire, marking the FTSE 250 lender's third deal alongside SME developer Beechcroft.

Look closer, however, and it reveals two of the most important structural shifts reshaping UK property finance and development: the retreat of high-street banks from mid-market housebuilding, and the explosive, largely unmet demand for age-restricted housing across the South East.
