Diadem Court is almost entirely flats, and every recorded sale is in one building, St Annes House. Sales here are sparse and mostly older — the last recorded sale was in 2005, so today's values are best judged from the wider W1D figures below. Too few recent sales to read a street-level trend, but across W1D prices have been easing over the last few years. The record shows 10 sales across 4 homes since 1996.
