This is a fundamental question. A good place to start is with a survey of your property. Most municipalities have a maximum percentage of your lot that you can build on and standard setbacks from your property lines that you will need to adhere to without needing to request special permission to build. On a photocopy of your survey you can draw in what your local setbacks are in order to define the location within which you will be permitted to build. In a best-case scenario, you will have the space to build without compromising too much on space or location; otherwise, you may need to request a minor variance, which would allow you to circumvent an obstacle such as a setback.
Efficiency does not always increase with experience, because as our woodshops grow older, they sometimes become unnecessarily rearranged or cluttered. And if you’re just now setting up your first woodshop, this shop layout should give you a great starting point. Each picture represents one half of a standard two-car garage.

Because workshops are rough and tumble places, the right fan for the job will have an industrial-strength motor and adjustable fan speeds. Easy-to-clean metal blades and a fully encased motor housing are also important features, especially if your shop tends to fill up with sawdust, wood chips and other fine debris. That extra layer of protection will help the fan motor last for years instead of being damaged by particulates.
Let’s be clear about one thing: No workshop is perfect for everyone. If there were, I could simply give you a precise plan to follow with clear dimensions. Every person who comes to the hobby, avocation, or profession of woodworking has his own particular collection of tools and his own peculiar work style, skills, and desires for the kind of woodworking he wants to do that gives him a unique approach as to how he will lay out a shop: where the tools should go, where lumber and supplies are stored, and how much bench area he needs.
