Canting is an architectural term for constructing part of a facade at an angle to the rest of the building. This gives the appearance of bits of the building being ‘pushed forward’ from the rest. It is particularly common in the late 16th century. A practical use of canting was that it would allow goods or furniture to be pulled up to the top rooms of the house without bumping the walls on the way up, or waste to be thrown from the window into the street without hitting the side of the house.
