Not for the winter without insulation
Easy to assemble. About half an hour at most. Lightweight. Totally waterproof as it has been through a good spell of rain and it remained dry. Ideal for a small dog. The only problem I have is that there is no insulation so the cats don't use it at night. (my dog was too big for it) My advice is to put some insulation in it before you put the roof on - some polystyrene for example but it does need some as the wood is thin. I put heavy tiles on the roof for insulation but it wasn't successful.
