Good looking manspace, , I enjoy seeing what others are doing as these places seem to evolve over time and are always a work in progress you may get some idears at this site where you'll find among some others my Mancave in its early stages,

Sam has written a neat book about the evolution of Man Spaces
also you might consider a projector or big screen TV to watch track videos or the ball game with the buddies, and for heat an infrared tube heater works great /AC is good to knock down any hunidity too.
There may be some more pix in my gallery, and this winter I'm working on a full kitchen there, got to keep up with my gurly figure.
Enjoy
