My current one is small and almost 15 years old. Thinking it will be a 2-tier deck coming out our kitchen door and I do have a walk-out basement below. I may put a concrete slab underneath(if money allows). I am not handy when it comes to this type of work but both my brothers are carpenters. I am looking for different ideas/designs and was wondering if anyone has some suggestions. Also looking for ideas/recommendations as far as material type. I have looked on-line a bit for info and was curious to see others thoughts. My family and I spend a lot of time outside and really want to utilize this space well. Thanks in advance!!
