The materials are rather good quality (pine stained thick enough, side reinforcements, waterproof coating on the roof), this does not "gnognotte". The design is well thought out (elevation to protect dry, roof pitch backwards to runoff from rain, access to the interior through the roof that rises and hangs ...) and plus it is aesthetically beautiful. Assembly is done without difficulty because everything fits well and is "in the face", screws are classified in a small cardboard support provided for this purpose (there are more in case we lose) , others are in small plastic bags, follow the instructions of the 4 assembly drawings; there is just the floor that is in 2 parts of uneven surfaces and it is not visible in the drawing but understandably amount shelter. No fault found. In conclusion, this is an amazing very good value for money (28,75 euros all inclusive at Amazon). At that price, no need to make one yourself. Anecdotally, I've bought for my old cat (18 years) who always likes to stay outside the day; shelter that will also serve him probably coffin.
