A DIY type person without a workbench is like a chipmunk without pouch cheeks. It just doesn't work and can have fatal results (can't collect the nuts eventually starving in the winter). The simple solution is to get a workbench, but to have workbench in an apartment posses some challenges.
1. There is no space. All space in an apartment is valuable real-estate, i.e. sacred and should not be soiled.
2. Workbenches tend to be unsightly and may have odours from time to time. Thus it will have to be beautiful and capable of combating anything but rose smells. All in all visitors should not be able to know it is a workbench (it's a secret).
3. Noise. Time hammering to the beat of some loud music or action movie. The neighbours will never know.
My solution was a cedar workbench with modular parts that act as storage and expandable work surface.
