How does Graham Greene use imagery in The Destructors?

Imagery:

On one side of the car park leaned the first occupied house, number 3, of the shattered Northwood Terrace — literally leaned, for it had suffered from the blast of the bomb and the side walls were supported on wooden struts. A smaller bomb and some incendiaries had fallen beyond, so that the house stuck up like a jagged tooth and carried on the further wall relics of its neighbor, a dado, the remains of a fireplace.
