Well you can only do so much with your given space. These guidelines are just general best-practices, but that certainly doesn’t mean everyone will be able to execute them to the letter. Even I make concessions for my personal situation. And yes, there would be differences in a Festool shop. I imagine everything would simply revolve around an MFT. :)
This will be a personal matter, depending on whether it will be helpful for finishing or sharpening. However, it is a good idea to look beyond your current use of this space to the next owner. Would it be beneficial to add plumbing hookups so that the shop could someday be an apartment, or an art studio, or an extension to your house? It could add to the resale value of your house to be able to create as flexible an area as possible by roughing in a bathroom and even a kitchenette area if you can. If this is done when wall cavities are open or before the slab is poured, your forethought could pay dividends but not cost much up front.
Depending on your situation, you may need to upgrade to 200 amp electrical service in order to meet the needs of your house and your shop. It may also be in your interests to add in a separate electrical service meter on your shop so that you can clearly write off electrical use for your business, or in future rent the space out and clearly separate out the utilities for billing your tenant. Generally, you don’t want to skimp on the power to your shop or on the lighting you include.
I agree with all of these tips in a larger shop. In a smaller shop (mine is just under 400-square feet) most things are fairly close together anyway. One of my original principals for shop layout was … how is a machining process performed on a piece of wood? Is the wood stationary while it is machined … or does the wood move through the machine? If the wood is stationary, I have tried to have this set for one side wall of the shop. To be specific, I have four machines in one line with a continuous table to support long pieces that might need cutting from one or all of those machines. The machines in that line are (from left to right) the drill press, the powered miter saw, the square-chisel mortiser and the radial arm saw.
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.
