The "cave" ground breaking was actually started back in Oct. 2013 before the rain and snow came by getting the concrete work done. The contractor wanted to do everything in the Spring of 2014, but I didn't want everything rutted up with concrete trucks. The building got started in Apr. 2014 as this was how the contractor had it scheduled. I completed everything I wanted to get done just this week. I may end up insulating later. Here are a few pictures of my 24'x36' cave with an 8'x16' porch.
