[5] Sir John Sapcote (d. 1501) added a large chapel at the south corner, described in Camden's Britannia as adorned with beautiful painted glass windows.

In 1526 John Russell, 1st Earl of Bedford (c.1485-1555), KG, married Anne Sapcote, daughter of Sir Guy Sapcote of Huntingdonshire by his wife Margaret Wolston[7] and widow successively of John Broughton (d. 24 January 1518)[8][9] of Toddington, Bedfordshire, by whom she had a son and three daughters, and secondly of Sir Richard Jerningham (d.1525), by whom she had no issue.

The house was rebuilt between 1662 and 1689 by his grandson Sir Thomas Proby, 1st Baronet, incorporating the chapel and gatehouse of a previous 15th century building.

Granville Leveson Proby, 4th Earl of Carysfort added a tower to the chapel block and a billiards room and kitchens to north-east.

The south front (garden) incorporates the 15th-century tower and chapel which date from the reign of Henry VII.

The ceiling also dates from the 18th century, but the decoration is Ashton's, as is the dining room, although the Gothic windows are replicas of those which were once in the medieval chapel.
