You might install bike lift in the floor or cutout platform below deck so you pull the bike up and "lift away"...! Think about doing a floorplan showing where you want electrical panel, can lights, plumbing, cabinets, workbenches etc. as your creative juices start flowing through your head. As Joy said earlier, most of us guys start thinkin' like making it better than a house..."man cave" with built in sound system in wall and ceiling...proper insulation and ventilation. Sink, shower and toilet are nice pluses.
