Firstly I tried to wear kit that didn’t stink – merino or merino mix tops make a big difference.
Then you go about finding or moving furniture…. a few of us shared a small modern freestanding ‘wardrobe’ on wheels for a couple of years that was pretty well ventilated and worked well. It doesn’t have to be near your desk – it spent some time near a printing area and some under a staircase.
I’ve moved filing cabinets to create an out of the way space at the end or behind and stuck on some hooks. Then use hangers. Likewise moved my bank of desks slightly to give space to hang stuff off the end.
– Coat-stands and hangers.
– radiators are great but not many buildings have them.
