Phase 1
A Visit to the Rookery of St. Giles and its Neighbourhood. (Volume 4): "We visited Dyott House, George Street, the ancient manor-house of St. Giles-in-the-Fields, now fitted up as a lodging-house for single men. The kitchen, an apartment about fifteen feet square, is surrounded with massive and tasteful panelling in the olden style. A large fire blazing in the grate—with two boilers on each side—was kept burning night and day to supply the lodgers with hot water for their tea and coffee. Some rashers of bacon were suspended before the fire, with a plate underneath. There was a gas-light in the centre of the apartment, and a dial on the back wall. The kitchen was furnished with two long deal tables and a dresser, with forms to serve as seats."
