The lost house

James Wyatt designed a new house for Sir Thomas Acland at Killerton, Exeter, in 1772

Have you visited Killerton's lost house? It was hidden in the woods for 240 years but rediscovered in 2017. Visit the house to find out why it was never finished.

Archaeologists have made an exciting discovery in the woods of the Killerton Estate. Hiding under the trees are the remains of an impressive stately home that would have been one of the grandest in Devon. The building started was in 1775 but abandoned two years later, and with few surviving records, the location of the building was lost. Now Killerton’s lost house can be seen for the first time in 240 years.

Have we found the house that Devon never had?

The lost house was re-discovered almost by accident. A 2016 archaeological survey of the parkland included a LIDAR image showing known historic features like the old deer park boundaries and Iron Age hill fort. The image also showed something unexpected. In the woods above Killerton house was a large rectangular earth bank. The site had become hidden by laurel, which a team of countryside volunteers cleared, revealing a huge space filled with brick and stone.  The size and shape matched the surviving plans of the building and original letters that refer to ‘the house on the hill’.

Archaeologists find proof of the lost house

In late July 2017 a team of volunteer archaeologists led by Joe Bampton from South West Archaeology made an exciting discovery. They dug a trench into the earth bank and uncovered the remains of several walls and a doorway. Joe explained, “The thickness and size of these walls tell me they were part of a big building of the same scale as Wyatt’s lost house. We found part of the interior walls and the incredibly solid exterior wall. We plotted the location against the floorplan and can say that the doorway would have been the entrance to the Billiard Room, which is marked on the floorplan. Judging from the material which lay over the walls it looks like the site was purposefully backfilled using spoil once the building work stopped’.

Volunteers unearth the walls, making a major find at the site of Wyatt's lost house.

Fi Hailstone from Killerton’s countryside team said, ‘We never expected to find such extensive foundations under the site. The find is proof that this site is where James Wyatt started building a huge new house for the Acland family. We’ve been able to fill a gap in Killerton’s history can now put the rumours to bed – Killerton’s lost house has been found.’
