Hundreds of historical artefacts are set to go under the hammer at a special auction.
Sir Professor Albert Richardson, who owned Avenue House in Ampthill, collected the items over the years.
The house was eventually passed down to his grandson Simon Houfe, who made the building available to the public to have a look round by arranged appointment.
But with “great sadness” the items are now being sold by Cheffin Auctioneers, who will hold the sale on November 14. The items will be available to view online from the Monday of that week.
Head of the painting department at Cambridgeshire-based Cheffins, Sarah Flynn said: “It really is a fantastic collection and something that I think a lot of people will be interested in.
“There are a lot of items up for sale, we have about 600 lots going under the hammer. There are a lot of paintings, furniture and fixtures and fittings.
“I think it will be very popular and a lot of the items will be affordable to most people.”
Sir Albert moved to Ampthill in 1919 and remained there until his death in 1964.
He was president of the Royal Academy and author of ten major books on architecture and social history, and of hundreds of articles and lectures.
He had the most discerning of tastes, but also wanted to use the collection and the layout of his rooms to help inform his many architectural students.
A constant stream of visitors came to Avenue House, from the leading architect Sir Edwards Lutyens and the poet John Betjeman to Queen Mary herself.
