New Website, Need Ideas

I've recently created a new website: design.medeek.com to start selling some of my garage, shed and studio designs. However, I would like to do some designs that take the standard garage or shop to the next level. In short I would like to design the "Ultimate Man Cave". Please give me some suggestions as to the features, fixtures, furniture and any thing else you can think of that such a structure should house within its walls. I will call the first attempt at this MANCAVE-1 and put the entire planset on my site freely available for download in PDF format.

We make custom chalkboard signs for restaurants and retail businesses. A popular chalkboard design we have been producing lately is a 'Craft Beer' or 'Draft Beer' sign or menu, where we custom design, cut and illustrate the sign and provide an area for you to write in the beer selections. I have had several private homes request a custom chalkboard sign for their man caves.
