Strutt & Parker has announced that May 11 is the date for this year’s open house day.

The event started ten years ago, with just one office – in Kent – taking part.

This year it involves 35 regional offices out of some 50.

Last year’s event was a huge success, says Strutt & Parker, with almost 1,000 active buyers viewing on the day and offers of over £61.5m in total being received. There were 580 properties available for people to view.

The concept is most associated with sellers’ markets, when there is high demand compared with supply, and originates from America.
