As i've stated before, dimensions, designs, materials, etc. are all personal preference. Considering i have never worked with wood or PVC before, i am extremely happy with the way these pieces turned out. And most important, the people i made these units for (my kids, 8 & 9) love them. I am only posting these pics to "share ideas" in this forum and to provide a glimpse of what we did. Not to influence or direct others to follow. These pieces were not built to sell. We followed no plan's or spec sheet's other than the ones we created ourselves. They were (fairly inexpensive) weekend projects i built with my kids help. They were built for "fun".
