Extra Large Dog House Plans – Free DIY Plans

This step by step woodworking project is about extra large dog house plans free. If you have a large dog and you want to build an appropriate outdoor shelter for it, then you should check out my free plans. I have designed this dog house with lean to roof, creating an extremely sturdy structure with a neat appearance. My plans come with step by step instructions and you can easily adjust all the dimensions to suit your needs. See my other DIY projects HERE.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.
