I'm guessing this is from the 1920s but really don't know. Netherwood was a guest house, and apparently the last residence of occultist Aleister Crowley.
"Johnny had owned and run, with her husband Vernon, a large, gabled Victorian guest house named Netherwood. The property stood in its extensive 4-acre grounds, wherein were outbuildings, a lawn tennis court, a large garden, shrubbery and many trees, on The Ridge, a road running across the flank of the upland area behind Hastings, about 500 feet above sea level. Netherwood's situation afforded extensive views of the town, its Norman castle, Beachy Head and the sea, which were doubtless part of its albeit wind-blown attraction to visitors.
