How I built this BIG dog house

As a beginner woodworker this was my first doghouse project My brother asked me to build him a BIG doghouse and so I did. I used the trial version of Sketch Up to design this before building it and it took almost 30 hours to finish this. Any constructive criticism is welcome as I am always looking to learn something. Thank You for watching My inspiration for this dog house was by Colin Furze I learned how to make lapjoints from Paul Ricalde
