Lyveden New Bield (sometimes called New Build) is an unfinished Elizabethan summer house in the parish of Aldwincle in North Northamptonshire, commissioned by Sir Thomas Tresham and now owned by the National Trust.

'[2] It was constructed for Sir Thomas Tresham, the fervent Roman Catholic of Rushton Hall, and is thought to have been designed by Robert Stickells.

Just as at Tresham's smaller folly, Rushton Triangular Lodge, his principal estate, the New Bield has a religious design full of symbolism.

The gatehouse has been removed to Fermyn Woods Hall, and the staircase was transported to America, where it was incorporated in the Edsel and Eleanor Ford House near Detroit.

However, in 2010, National Trust experts studying photographs taken by the Luftwaffe during the Second World War discovered the remains of an Elizabethan labyrinth, garden and orchard in the grounds.

[12] The National Trust has reconstructed Tresham's orchard, which originally contained 300 fruit and nut trees, as well as restored the moat on three sides of the labyrinth.

[15][16] Sir Thomas Tresham died in 1605 following decades of religious persecution, his once vast wealth having been severely depleted.
