Final offers for the RAF Stanmore Park site in Uxbridge Road must be received by noon on Wednesday.

Mark Wilkinson from Knight Frank Estate Agents said: "We don't expect to receive offers much before the deadline, they will probably start flooding in around 11.30am."

The need for planning permission from Harrow Council to develop the land means that offers are likely to be conditional upon that being granted, in which case Knight Frank expects bids of over £20 million.
