Query: The design is great, but not the quality

The design is great, but not the quality. The black wood frame on our dog house was split. The wood absorbed rain water the the wall swelled. The roof also absorbed water. I had to caulk the the roof and coat the entire dog house with Thompson's Water Seal. It was very easy to put together. My 11 year old sons got it done within 30 minutes.
