Why is the wooden bench turned to face the house?

The fence was turned to face the gardens and the house because of the view.... had the fence faced in the other direction, it would have looked out on a high, wire fence topped with barbed wire. Beyond the fence everything was flat and without beauty, even the houses and huts were ugly.

The seat was turned to face the house - which, usually, would be a strange thing to do but on this occasion she could
understand why. About twenty feet further along from the garden and the flowers and the bench with the plaque on it, everything changed. There was a huge wire fence that ran along the length of the house and turned in at the top, extending further along in either direction, further than she could possibly see. The fence was very high, higher even than the house they were standing in, and there were huge wooden posts, like telegraph poles, dotted along it, holding it up. At the top of the fence enormous bales of barbed wire were tangled in spirals, and Gretel felt an unexpected pain inside her as she looked at the sharp spikes sticking out all the way round it.
There wasn't any grass after the fence; in fact there was no greenery anywhere to be seen in the distance. Instead the ground
was made of a sand-like substance, and as far as she could make out there was nothing but low huts and large square buildings dotted around and one or two smoke stacks in the distance.
