Following a basic engineering project methodology, I'll start with the aims and assumptions:

Aim

To create a highly functional, ergonomic, and safe space for woodworking.   

Assumptions

• That I will be using the workshop by myself.
• That the workshop will be used almost exclusively for woodworking using only hand tools (includes powered hand tools but not large machinery).
• That the constaints of the workshop dimensions will remain fixed (no extensions!)
