Minor variances are applications to your municipality to suspend a particular by-law to allow your project to proceed, based on common sense or precedents set by other buildings in your area. If your municipal committee of adjustment denies permission because a neighbour voices concern over the development, you would have to appeal the decision to the municipal board of your particular province. In that case, you may be better off looking for another piece of property with an existing structure that you could renovate, more relaxed zoning regulations, a larger lot, or more congenial neighbours.
To experiment with different wood shop layouts, measure your furniture and equipment to sketch onto your plan in different positions. You can also make cutouts of the footprint of your items so you can easily move them around your floor plan to see how best to arrange them. As you do so, don’t forget to leave adequate spacing around tools and tables.
Natural Light. Natural light is best, so any windows that offer illumination to the space should be put to good use. If you have little sunlight in your shop, locate your workbench so that its work surface gets whatever there is. Even the best eyesight is made better by good light, so the close work to be done on a benchtop benefits from the natural light.
As the comic George Carlin might say, a shop is mostly just “a place to put your stuff.” The physical aspect of a shop is indeed simply a space of some kind — a garage, a barn, a teepee — that keeps the rain, rust, and robbers away and houses a collection of implements needed to saw, plane, slice, sand, and pound raw wood into useful objects. But just like the difference between a house and a home, what transforms a building full of tools into a comfortable workshop goes beyond the mere physical aspect.
