Didn't take that long really ! Was going to buy one in £450
But order some wood off a mate for my fence down the side of the garden 200 length 3.6 length 4" wide when he landed he had 600 length ??
So I thought I might as well build one
All insulated in side the kennel heat lamp on a timer and the led lighting for the pen on a timer
All in all I'm very happy with the out come drain in the pen floor as well linked direct to main sewer !
