Downlighters: these are forms of spotlights that rely on the reflected light off the floor; a downlight can be used to illuminate an object directly at a pinch. Downlights come in all sorts of forms that give a narrow beam that spreads down to the floor. They are recessed or semi recessed and may be a feature or extremely discreet.

Down pipe: Pipe, which carries rainwater to the ground from the roof gutters.
DPM: Damp-proof membrane. Usually known as DPC Large area of damp-proof course (q.v.) laid, for instance, under a basement floor. It is a sheet material or coating that has a low water vapor transmission property, minimizing water vapor penetration in buildings. Damp proof course is a thinner strip used below bottom plates of timber framing or in brickwork.
Dragging: (paint effects) this is a process which creates fine vertical irregular lines, a soft textured look to walls generally. It is achieved by applying a translucent colour glaze over a base coat and then using a dry wide brush, dragging it over the glaze before it dries. It gives the impression of fabric covering.
