The settlement is approached from Hadleigh via a minor road. No direct vehicular access is possible from the B1070 at Upper Layham. A watermill dating from 1905 can be found on the course of the river Brett (it was built to replace a larger mill which burnt down). The mill is on the footpath between Upper and Lower Layham; the only direct route between the two settlements.
The 16th century Overbury Hall features in a Constable painting.
The two Layhams were recorded in Domesday variously as "Latham", "Lafham" and "Leiham" and historically may often just be refered to collectively as "Layham".
