I've strung stuff out under my desk, hanging clothesline style on phone and computer cords. That's especially effective if you have a space heater or fan under there.

As has been suggested, wear wool and you won't have to worry about smell. Baring that, take a shower before you leave for work and the sweat won't cause an odor.

You may have a place to park your bike such that you could use that as something to hang clothes from. There's more stuff to tend to in the winter or when it rains so you might have to take advantage of every bit of real estate you have available under some circumstances.

You said you shower at work. Is there not a locker available also? I don't keep valuables in lockers at work so I can leave mine open and have shirts and jackets inside and on hangers hooked on the open door as well.

Baring any of that, maybe there's space at the bottom of a stairwell that is out of site. Or a room with phone lines and electrical connections/routers and such. It's likely nobody goes in places like that much though you might need to ask for a key.
