Yes, if you don't have dust control.

As a minimum change your working methods to reduce dust.
Do anything that produces significant dust out of doors, in the garden/yard, on the terrace/balcony. Avoid woods that are known to be "nastier". Avoid sanding in favour of planing and scraping. Use knifes, chisels, gramils instead of routing. Vacuum up the dust. You can attach a domestic vacuum cleaner or a small workshop vacuum to many power tools when you use them. Don't use epoxy glues - somehow these seem to accelerate the development of wood dust allergies.
If the room is big enough to have even a single bed in it and some walk round space on one side and the end, then you do have enough space for some sort of dust control. You just have to size it accordingly and maybe make some compromises elsewhere. (I am assuming that the bed is gone and it is not being used as a bedroom at the same time). A portable vacuum cleaner attached to any power tool as you use it and sanding out of doors (but using a dust mask) will get rid of a large amount of the issue. However, if you start making significant numbers of instruments then you will have to re-think your working arrangements.
For a serious workshop a sanding table where the dust gets sucked away as you work is a great idea. There are lots of articles about dust control if you search. If you are planning a workshop in the future, plan in the dust control right from the beginning. Apart from collecting dust at machines and at a sanding table, a room air filter is another element.

This guy is often mentioned on the internet. Might be a good starting point.
