[Old Plan]
The four main changes are that I have [1] substituted one large pentagonal bed and a small deck for the two rectangular herb beds under the gum tree, [2] widened the path, [3] split the monster glass/hot-house in two (now, half hot-house, half chook-house), and [4] added a lower path/deck.
[New Plan]
The minor changes include moving the garden seat closer to the gum (so that it is opposite the deck and, therefore, has a clear view over the house), moving some of the privacy screens and fruit trees. Missing from the plan is the water-tank in the first plan, but I will re-instate it once I have done some more measuring.
A few of these changes were forced on us. If we build anything with a floor-area of more than 10m sq we need planning approval; to get planning approval we need a geophysical survey because we are in a mild land-slip area. Expensive and time-consuming. Two separate structures of 10m sq are fine, one which is 20m sq is not: so the 20m sq glass house has become one glass house and one chook house.
[The Plan]
We wanted chooks and originally, but vaguely, planned on putting them in the top-left (above the X) once the fruit trees were established. Having seen J. and M.'s majestic
Summer Palace, and having been inspired by
this chook-house on J's blog, we decided to incorporate the chook-house into the plan. Also, since it turns out our neighbours are deaf and stupid (but not, alas, dumb) we thought that the closer we placed the chook-house to their bedrooms, the better.
[Chook House]
As you can see (I have marked north on the New plan), the night-quarters for the chooks will face the morning sun and be accessible from the path behind/outside for early-morning egg-raids. And, because of the sharp fall in the land, will be well clear of the ground, without requiring a steep ramp. Something like this …

except with an asymmetrical roof, and the coop lower … you get the general idea!
[Planning]
Some of the other changes were inspired by plans that appear in the DIY book (top right in the picture below), which was a birthday present from M. Others are refinements which result from closer and longer observation. For example, now that we have cleared most of the back fence of ivy we have discovered that we will
have to build reasonably high retaining walls, a lot closer to the back fence than planned, because so much soil has washed away from the back fence that the bottom of the fence-posts have been left clear of the earth and the fence is falling over.
So, we need to build a retaining wall higher than the bottom of the fence, which is about 40–60cm above present ground level. In fact, we need to build this wall as high as we can without requiring planning approval (which is 1m), and we need soil to put behind it. By widening the path, we can use all the excavated soil to back-fill the new retaining wall. The side-benefit of this is that we get a much wider path and since the existing path is
way too narrow for a wheel-barrow, this is a good thing. Also, on a block with precious little flat ground …
[Herb Garden bed, elevation]
The lack of flat ground, and the need for some flat area in the garden, is the reason for the small deck, which is on the same level as the path, and extends the flat area out, under the gum tree. The large pentagonal herb bed is alligned to North. The point closest to the house will have quite a high front face to the retaining wall so that the top is level is 20cm above the path at the back. The front point could be as much at 1.2m above present ground level, which would require six 20cm-wide sleepers—close to the limit, and more than can be supported without spending serious money on steel uprights. So, we think we will construct the bottom two rows in masonry and cement the supports into this base.
[Vegie Garden bed, elevation]
Partly to cover up the masonry, and partly because a path between the house and the vegie beds will be useful anyway, we are likely to use the same masonry to support a duckboard path (see above, at left). Somehow or other we will join this path with the path between each garden-bed and with the deck, but where we will put the steps up to the deck won't be clear until we do a lot more measuring!
