hi Chris, I done something similar to what your thinking of doing, you can find out how i created my garden layout in the forum: O,G and Larger Scales, Garden & Live Steam. Then go to the article: Hornby steam in the garden, good luck with your prioject

I can see loads of potental in your garden, you could use the shed on the R/H side as your control base, and have a elevated track bed around the perimeter, a bit of planning here would give you a very enjoyable layout.
