Approximate location (postcode centre). Map data © OpenStreetMap contributors.
Averages cover every recorded sale in SW3 3JJ (2015–2025) and are not adjusted for house-price changes over that period — where the market has risen, older sales pull the average below today’s values, so treat this as a rough guide rather than a like-for-like comparison.
This address covers more than one registered unit or interest (for example separate flats, or a leasehold and the freehold). The Property column shows each one. These are separate Land Registry entries, not repeat sales of one home.
