Hello there

We're in the process of building our house and I've been thinking down
the line to the gardens landscaping. Our site from front to back falls
away in the last 1/3 of the site. With that in mind I'm planning to
have the patio area at the back of the site at a different level to
the lawn at the front (in the order of 1 metre difference). Trying to
do things differently, I'd thought of using "gabion baskets" (Wire
mesh baskets filled with rock) to support this drop in levels,
possibly with a decorative stone on the open face of the basket
(facing into the patio)

The concerns I have are....
Will it stand the test of time? (weeds, sag,)
How do I terminate the lawn as the garden drops into the patio? Flower
bed on top of the baskets?

Any opinions and advice would be greatly appreciated
Thanks
Sean
