These are all good tips, and apply to pretty much every shop. Like all things woodworking they need to be tweaked so that it’s right for the individual. For instance, I have a basement shop that’s not tiny but it is still space constrained, so worrying about the optimal layout for my ts/jointer/planer is a little off the mark since I don’t have to walk very far; instead, I want to be sure that related tools can be used *at the same time*. Having to move the planer out of the away so that I can use my TS is crazy if it can be avoided. However, interference between my drill press and my planer is less of an issue because they usually don’t get used at the same phase of a project.
If you want to run a business operated by yourself and more than one employee, you may run into zoning issues if your location is zoned for residential use only. It’s common for municipalities to allow and encourage home-based busi­nesses but there will likely be a maximum area that you will be permitted to add for business purposes. If you try to build a shop that will contribute noise and traffic (from employees or deliveries) to an urban neighbourhood, you run the risk of run­ning into opposition from neighbours concerned by the impact your shop will have. Your municipality will have planners with whom you should consult as you begin to define the possibili­ties that your property will allow.

If you have to pick up long lengths of wood from the lumberyard, throw a spring clamp in the back of your vehicle. Use the clamp to attach the warning flag to the end of the protruding lumber. The clamp’s easy to slip on and off, and you won’t have to fuss around with staples, nails or string. — Steve Parker. Plus: Learn more about how to transport large items in your truck.
Electricity. It’s a rare workshop today that doesn’t need electricity; most need multiple receptacles of high amperage (20 amperes or more). Are there plugs available or will you need to add new lines and circuits? If you need to add wiring, when laying it out keep in mind that there’s no such thing as too many outlets in a workshop. The fewer (as in, ideally, zero) extension cords the better; they’re safety hazards. A good minimum is to have receptacles set at no more than six-foot intervals around the perimeter of the room, and, if possible, flush-mounted floor plugs in the central area.
Shop layout is all about making the best use of space. Place your machines so that you have adequate “safe space” that you need to work around them. The “buffer area” beyond that is the amount of room you need to run large stock though a given machine, keeping in mind that buffer areas can overlap between machines. If you want to get more organized, buy some 1/4-inch squared paper, make scale models of each machine including the safe space around each, and place them on your model shop layout. Remember that buffer areas need to be long enough to put an 8' sheet through a table saw, or a 6' plank through your planer, for instance. I raised my planer, so that I can use the area above my router table to pass long planks through the planer – all it takes is some modelling, and a little shuffling, and you will find the layout that works for you. Each space will have chal­lenges; I had the area under the stairs that was wasted space, so I installed the dust collector there.
Plan to invest in a set of bench chisels, both standard and low-angle block planes, a No. 4 or 4-1⁄2 smoothing plane, and a No. 6 jack or No. 7 jointer. Between them, these planes will true edges, flatten glue-ups that are wider than your thickness planer, and tame tricky grain that would tear out with a mechanized planer. They also do fine trimming better than any other tools.

Is your cellar damp? If so, you may have to correct that problem before installing your tools and lumber supplies. Insulate pipes to prevent condensation. Make sure your gutters outside keep rainwater running away from the house. Cracks in the cement floor or walls should be filled with hydraulic cement; a high water table may necessitate a sump pump to collect water at a low point and pump it out. Any or all of these circumstances may also require a dehumidifier. In any case, dampness is unacceptable where power tools are to be used because of the risk of electric shock.
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.
