House surveys in Devon

Devon has the largest stock of cob (earth-walled) houses in England, many with thatched roofs, together with red sandstone in the east, limestone around Torbay and Plymouth, slate and granite near Dartmoor, and large Victorian and post-war suburbs in Exeter, Plymouth and Torbay. Plymouth also has a notable concentration of post-war prefabricated concrete houses such as Cornish Units. Common survey issues include damp in cob and solid walls caused by modern cement renders and paints, thatch condition and insurance, river and coastal flooding, steep sites with retaining walls, radon around Dartmoor, and mining legacy in west Devon.
