Thanks to this post from MARTIN & AAM's blog, this is the first time I ever seen this beautiful "Rain Chains".
It works the same way like the downpipes that connects to your gutters. But it's definitely looks much better than the colourbond or ugly PVC ones.
This one is from www.rainchain.com.
The rest are from www.rainchains.com. Yes, there's an extra "s" at the end, and it's a completely different company...
Found this site selling a 2.7M chain for AU$475, not cheap and it doesn't look as good as the ones I mentioned above.
Lots of people spend lots of money for water features, may be Rain Chains are a easier/simpler/cheaper alternative??!!
Any way, one extra thing for you to consider if you want your house to look special when compared to others in your neighbourhood!
