DIY Concrete Dog House

This modern concrete doghouse is made out of Quikrete Countertop Mix poured into a mold made out of 2x4s and Masonite. I poured the concrete in layers so that the weight of the wet concrete would not push the thin Masonite out. For full instructions go to I used bags of Quikrete Countertop Mix in grey and the finished doghouse weighs about 100lbs. I know a lot of you will ask about reinforcement and I would refer to the strength test I did with the Lego formed nesting tables.
