We bought these building along with the farm playbase to try to create a "real" farm for our little boys. These buildings take quite a bit of building...so do set aside quite a bit of time to put them together. When they're together they look great, but we found them to be really flimsy - far too flimsy for our little boys to be able to play with! They can barely withstand a gentle touch without a part of the roof falling off, so putting animals or vehicles inside and then bringing them out again just couldn't happen without wails of disappointment. Incredibly frustrating!! In the end we took them to pieces, (not hard, as you can probably imagine!), and put them away...never to see the light of day again.
If you want to create a great looking farm then these will do the trick. BUT, if it's going to be played with by youngsters then I would really recommend finding something that's a lot more durable!
