Once the workshop location is determined, it's time to begin planning how to lay it out. First, acknowledge the need to formulate a plan that's realistic in terms of the space allotted. The size of the structure or workspace will place some constraints on how much can be done. Taking into account size limitations, begin fashioning a plan that keeps efficiency in mind.
To plan my shop, I used a modeling program on my computer, but you can use the drawings I created to plan an efficient shop on paper. Download and print the PDF below and arrange them on graph paper to create a plan view of your shop. Take the time to work out the most efficient placement of benches, cabinets, and machines, taking into account infeed and outfeed zones as well as ducting for dust collection.

If you choose to hire a draftsperson or architect, they may charge you based on the square footage of the area you are proposing, by an hourly rate for their time or as a percent­age of the cost of the structure. Costs of building permits will be a percentage of the estimated cost of the structure you are proposing (e.g., $15 permit fee per $1000 or 1.5 percent), or a cost-per-square foot depending on your municipality (e.g., $1.20 per square foot). Design work and permits will both dif­fer depending on the part of the country in which you will be building, so ask the questions as you move ahead. One of the costs that is often overlooked in planning is the increase in annual property tax you will pay once your improved property has been reassessed.
To make sure you account for any existing obstructions, it’s a good idea to make a measured drawing of your workshop area on graph paper, noting existing furniture, built-ins and large items on the plan as you go. For example, a common one-car garage workshop layout has built-in tool cabinets and shelves around the perimeter where they won’t impede parking, but you may also have to get clever about folding work tables and saw horses that you can set up as needed in the middle of the garage when you’re working on a project (and cars are parked outside).
Often times at first glance a board looks straight and the fact that it is actually bowed or has some warping isn’t always obvious. So the trick to knowing for sure, is to hold the board up towards your face, with the other end on the ground, and look at it at a downward angle (as shown in the below photo). This method will allow you to see if it is bowing at all.
If your shop is long and narrow, option 2 provides maximum space to the left of the fence for handling large sheets of plywood. If you often work with full sheets of plywood or other sheet goods, you might want to build the table saw into an extension table surround, as San Diego woodworker Pat Curci did in his small shop (see the photo). The surround offers support for large panels, as well as provides an ample work surface near the saw.
