Softwood is most commonly found in the regions of the world with lower temperatures and is typically less durable, lighter in weight, and more vulnerable to pests and fungal attacks in comparison to hardwoods. They typically have a paler color and a more open grain than hardwoods, which contributes to the tendency of felled softwood to shrink and swell as it dries. Softwoods usually have a lower density, around 25-37lb/cu ft, which can compromise its strength. Density, however, does vary within both softwoods and hardwoods depending on the wood's geographical origin and growth rate. However, the lower density of softwoods also allows it to have a greater strength with lighter weight. In the United States, softwoods are typically cheaper and more readily available and accessible. Most softwoods are suitable for general construction, especially framing, trim, and finish work, and carcassing.
Alternately, a detached shop can often be located closer to your property line and offers you a bit more freedom in terms of the type of foundation you can use. It may give you a sense of welcome separation from your home and open up yard space or allow a deck on the back of your house that would otherwise be lost behind your shop. In an urban setting, if you would like to have a wood stove in your shop you may find it more challenging to find an insurance carrier that allows one in an outbuilding. Also, outbuildings can be subject to more stringent height regulations than additions.
Unless you’re a big fan of frequent shop remodeling, planning the layout of your workshop early in its development will save you a lot of time and trouble and also can keep you from spending years in an uncomfortable, poorly organized space. And if you already work in a shop that’s as organized as a trailer park after a tornado, careful planning and a little remodeling is likely to help you make a quantum leap.
