DIY Projects: Pavilions and Workshops
Pavilions and gazebos are simple constructions and good for your first DIY project.
We have selected a couple of workshop projects as well - because if you are a shedbuilder, you would definitely need a place to build things.
Building a 10'x12' workshop

A couple of folks built a 10' X 12' workshop shed in 10 weekends.
The cost of this workshop went up to $1,000. The project is very well documented with photos from every stage/weekend.

Building a workshop from scratch
This instructable is about building a workshop in existing basement. So it's not about buildding a workshop shed or garage but about shelves, workshop table etc. It's still interesting - to build a shed you'd need a workshop too.
On the Making of Your Own Pavilion
John's guide to build a tent/pavilion. The author recommends to get the The Pavilion Book if you really want to start building. I think the guide is good enough to decide if you want to build a pavilion or not.
