He built the house in the Elizabethan style, the then-current early Renaissance architecture, adding large windows to the south of the porch.

Cromwell visited Chavenage House, and Stephens supported his planned regicide, and although he was not one of the signatories of Charles I's death warrant, he is nevertheless said to have died of remorse soon afterwards.

It is also recounted that on the day of the Nathaniel's death, his ghost was seen leaving the house in a coach driven by a headless coachman dressed like the hapless king.

[6] In 2024, having skipped a generation for tax reasons, Chavenage came into the hands of James "Hank" Lowsley-Williams, a former pro cyclist and presenter on Global Cycling Network.

[7][8] James has launched a YouTube channel called Life at the Manor where he is documenting his journey in remodelling the house and improving its profitability.

David Verey and Alan Brooks, in their first volume of the Pevsner Architectural Guide to the county, describe Chavenage as "the ideal 16th-century Cotswold stone manor house".

[10] Chavenage has been used in films and for television programmes, including Barry Lyndon, The Ghost of Greville Lodge, the first Hercule Poirot story The Mysterious Affair at Styles, a 'gotcha' for Noel's House Party, The Barchester Chronicles, Berkeley Square, Cider with Rosie, Grace & Favour, The House of Eliott, Casualty and Dracula.

Two productions were shot at Chavenage in 2013, The Unknown Heart, based on an idea by Rosamunde Pilcher as well the historical drama New Worlds (Channel 4), starring Jamie Dornan.
