That looks great. It looks like you thought this out a bit before hand and did some planning. Great job. I'm curious to see how the drylok works out as I went with pond shield myself for the 3 I built. Glad to hear you did this with the help of your father. As a father I enjoyed having my daughters help me out, though they are a bit younger (under 10) and couldn't do it themselves. I look forward to helping them with projects as they get older. The time spent on a shared project was great. Are you planning to stain the outside? Drylok is not needed there, though I did seal the air holes I made. I look forward to seeing the finished product.
