Hello m8. I have built one of the Miniart Buildings for my "Seem's awfully quiet don't you think" Dio, I found it ok to put together once I got my head round the vacu-formed plastic. You do get loads of extra bits, that you might not use, nice to fill out the spares box! The only advice I can give is make sure you have a sharp knife and take your time and sand,sand and sand again to ensure a good fit.
Have a look at the Miniart web site they have a assembly guide on it.

Good luck with the kit
