Popular and easy to work with, cherry is in high demand for its reddish-brown color and ease of staining and finishing. Cherry likely won’t be at the local home center, but should be at a lumberyard for a somewhat expensive price. This hardwood is a very common material for furniture, and is resistant to normal wear-and-tear, but it is best for indoor pieces.
There are benefits to either approach. Sharing a common wall with your house can require some careful soundproofing but can reduce heat loss and exterior finishing costs like siding. A shop located in an addition is more likely to be allowed to have living space or storage space above it, and it may be easier to make use of the existing plumbing and electrical and heating systems of your home to service your shop space. Another advantage of an addition is not having to run to an outbuilding in minus-30-degree weather or a summer downpour.
In most small shops, once the key machines are in place, others are arranged wherever there is room for them. There typically isn’t enough free space for these tools in the middle of the floor area, although sometimes you can tuck a machine into an unused space. For example, in a shop where the table saw is in the center, a shaper (or a router table or spindle sander) with a table the same height as the saw can be put on the outfeed side of the extension table (see the illustration). Also, building a router table directly into the table saw’s extension table is a great way to save space, as well as make use of the saw’s fence for routing operations.
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.
