It is my first kennel ive attempted building mate and cost me 50 for roofing.. 45 for main beam structure of a reclaimbed timber bloke and picked up loads of free pallets for dog box. Just knocked them apart and used the wood. Double walled the dog box.. I already had plenty yongu n grove cladding aswell. And then say 20 - 30 quid on locks and hinges and screws etc. So not bad really. Cheers
