Hutchinson's favourite location while making the film was Kingston Russell House in Dorset – used for Norland Park, the Dashwood family home at the start of the film. After considering mulitple locations, Kingston Russell was chosen – a house that has not appeared on screen before.
Standing in as the Dashwood family's original estate – the one they are forced to leave after the death of their father – Knebworth House in Hertfordshire was used primarily for interiors and some shots of the grounds. Filming took place here in July 2025. The house's accurately preserved historic interiors have made it a natural choice for period drama: The King's Speech, The Crown and Nanny McPhee have all used it. For the exterior of the same estate, Broughton Castle in Oxfordshire was selected – the moated medieval manor house that has appeared in Shakespeare in Love and Mary & George. On screen, the two locations read as one seamless house.
Austen set the novel in Devon, and Oakley took that seriously. Specific filming took place around Dartmoor National Park – near Princetown, Tavistock and Gutter Tor – with local papers including the Totnes Times spotting the cast and crew on the wild landscapes. The derelict Ditsworthy Warren Farm on Dartmoor was selected to become Barton Cottage, but needed significant preparation. The team added period-appropriate windows and a door, patched up the roof, removed rubble from outside and added planting – a temporary renovation that took around 10 days. Ditsworthy Warren Farm also appeared in the 2011 adaptation of War Horse.
Filming took place in parts of Batcombe and Hilfield in Dorset – areas that offer sweeping rural landscapes and plenty of natural light, their countryside character extending the film's West Country geography beyond Devon.
