The whole civil parish gently slopes from southeast and south to north. Elevations range from 92m AOD in the southwest of the developed area of New Barn in the east which is on a wide rise, to 45m AOD in and around the chalk pit just west of Longfield across the largely disused HS1 south-of-London link railway line towards Southfleet (just north of the village). Just above this is the tiny settlement, a farmed area named Pinden, to the south, however before this on the road towards London is another named community, no more than a row of cottages on the road named Whitehill.
