Hi, yeah it will be worth it. Today we spent a couple of hours digging the ground, unfortunately we have hit a problem, we have discovered a massive tree root which goes deep into the ground and then upwards and down again, not sure which tree it is to but it is right in the way, so we had to leave that bit for now, so the slabs go up to that point. We are going to double the slabs to raise the aviary off the ground, so will need some more slabs, luckily my grandad has lots left over from his greenhouse, we will bring some back on saturday and put them in on sunday. That gives us time to dig the ground, just not sure what to do about the root! We had a pond but it was filled in many years ago as it got too much to look after, we are planning in putting in a small pond maybe later this year after we have got the aviary done. The garden will look nice once everything is done, we have the bird feeders, will have the aviary and a pond so it will be great for wildlife and us. We can sit on the patio and watch the chipmunks as well as spend lots of time with them, thats the part i am most looking forward to. Sorry about the pictures they are abit rubbish.
