That is truly a work of art! We have a similar design, but ours looks like the getto compared to this palace! Beautiful work, and great attention to detail.
It's not hard to build in the way I have, nor is it really that expensive.
You just have to plan ahead, take your time.
From the time I started planting trees to when the birds will be in it, 6 years will have gone by.
(main reason is too many projects on the go)
