You have to work with the space you have Ned so don't fret about your mancave. I am blessed with being single so I can use all my house though I restrict it to a couple of corners of the lounge, some spare bedroom storage space and part of my business workshop. Once the Environment agency have finished tunelling under my house I will upgrade my manshed into a hull building workshop. (They have to put it back over the hole they dug to get lots of big pipes down).
