The built environment (3)
Buildings are often altered during their lives, so that what we see of them, as of the countryside itself, is a historical collage ( a palimpsest). Quirky details often arise from supercessions and superimpositions of different building purposes and periods - if you walk through the town, see if you can spot some. Shop fronts may be grafted on to the ground floors of buildings that began life as houses. Buildings may be divided internally in ways that create oddities of external appearance.
After the walls, much of a building's structural interest is in how it supports its roof between the gables, but this is usually concealed from the passer by. Much of the remaining interest lies in the detailing - of the masonry, render, carpentry and joinery, and all their furnishings and decoration.
