My advise would be to start out with creating nice simple cube shapes and getting the angles, sizes and shapes in place first.

Lock off the camera and use the perspective and orthographic views to model with, render out with the secondary lock off camera.

Approaching the modelling can be done in lots of different ways and every artist could apporach it differently. For me tho I would start off with the standard cubes and start refining from there or model the horizontal planks or you could attempt it with displacement mapping...

The easiest approach would, for me, would be to model and use the poly cubes placed at the start to get the correct angle and position for the camera. Opportunity for lots of duplication. So good luck and I am sure it will turn out well...
