I'm currently building a shed/workshop area in my back yard. I've had to rebuild part of a retaining wall and built another retaining wall from scratch before I can even start building the structure. I have the site pretty level and I think once the ground thaws out a bit more I'll break ground on the actual structure of the shed. I've built both a shed and a chicken coop for my parents. Apart from a couple of new screws that we bought the entirety of the chicken coop was made from reused materials. The aluminum can roof that I made for the chicken coop was definitely not the best idea. It took forever but worked decently well. Buying a pack of shingles would have been much more efficient but i guess less memorable.
I bought a GoPro to document the progress that I'm making on building the Shed/Workshop and I've been posting updates to YouTube. The full set of videos can be found here. Over thanksgiving this year I stayed home and got a ton of work done on it with my awesome girlfriends help. This video makes the result of that week of pretty hard labor seem a lot easier than it was:
When the shed is actually finished I'm hoping the final time lapse video should be pretty epic.
