Auctioneers say they are open to offers for anyone who wants to buy a grand staircase, inside a Hawthorn mansion, that failed to sell at auction.

The home's aristocratic owners, an English Earl known as Keith Rous and his wife, Countess Rosie, are renovating, you see, and decided that the showcase jarrah entrance stairs, with rails and balusters thrown in, just had to go.

It was among more than 600 lots – a slew of the home's contents – that auction house E.J. Ainger put under the hammer at the two-storey house in Isabella Grove over more than eight hours on Sunday.

On sale was everything from drapes to 17th century chests of drawers, an antique tapestry, a piano, chandeliers, leadlight windows and 80 works by artists including Charles Blackman, Ben Quilty, Sidney Nolan and Brett Whiteley.
