Thomas Tresham began the foundations of the New Build in Lyvveden (near Oundle in Cambridgeshire) in 1594, and it was left unfinished upon Thomas Tresham’s death. All that survives of work at Lyvveden is the remaining portion of the Old Bield, which was probably built by Lewis as an addition to the older manor. Lewis’s son William, who died childless in 1643, was the last of the main line of the Treshams.

It was sold in 1668 uncompleted. It is remarkable that anything was built at Lyvveden at all, yet even more amazing that it remains today.
