What some people would consider "the ideal hacking environment" I'd consider a bare minimum. It's been a long time since I worked some place that didn't have 24 hour access, 24 hour A/C, decent lighting, and so on.
A controlled auditory environment. I can't work when the guy in the next cubicle is yelling at a vendor on the phone, and I can't work if I can't occasionally yell at a stupid vendor. Same with music. I need it sometimes, but I don't want to hear anyone else's.
Headphones are a no-go... I can't get up and move around. Maybe bluetooth headphones would solve the problem.
Lots of bookshelves. All the way to the ceiling, at least on one wall. Places to put up my posters and pictures. An expectation that *good* artwork won't get pilfered. No hassles about work-area toys.
Couch, preferably a variety of couches.
Offices have plusses and minuses. Plus: you can get away from people. Minus: people can get away from you. Cubicles really do seem more efficient, but we need get-away-from-people space. Maybe a couple of quiet rooms with couch/desktop/workstation/closed door/sound system... and a timer?
Plenty of ethernet. At least 4 ports per office VLANnable to whatever test lans you need them to be on. And as many hubs and switches as you want for in-office things.
Room for at least 3 workstations in the office, per person. Sometimes you really need to have an end-user system for end users.
A real electronic workbench you can take stuff to beat up on hardware on, including good lighting and magnifiers and soldering iron and lots of little boxes full of stuff like solder and sockets and common parts.
A full size arcade Tempest machine, in good shape.
