Portman Square, Marylebone

The registered record for Portman Square runs to 4 sales, and the middle of that range is £1.25m. Prices have ranged from £25,000 to £2.70m, so an asking price only makes sense once you have seen the specific floor, aspect and state of repair. 50% of what sold was other property, and 4 of the last 4 were leasehold — worth checking the term before you offer. The most recent registered sale went through on 3 Jul 2026.
