I would love to own an old WW2 Uboat put it in my backyard and set it up as my home, i would have the control room as the living room, forward torpedo room as the bathroom. the officers mess cleared out to be the kitchen and the rear compartments as the bedrooms, sonar and radio room will be my computer room for when playing subgames - how realistic will that be! :P. The periscope would still stay but alot of everything else would be renovated. The conning tower hatch would be the way in and out. No windows, the persicope is the window.Yep i have it all visualise in my head. Now hoping one day it will be a reality.
Edit: the boat would either be an VIIC or IX
