Tullimaar House is a mansion just east of Perranarworthal in west Cornwall, England, United Kingdom; it is not visible from the main A39 Falmouth to Truro road, and stands in private grounds. However, the white gate forming the entrance to the property can be seen from the road.
It was built in 1828 for Benjamin Sampson, born in 1770, who was originally a "bal carpenter" (i.e., carpenter at a mine) and founded the gunpowder works at Kennall Vale.
