SS, You say you have a small cottage and you would think that underground is the way to go. Is your floor flag stone or wood? If wood cut out a trap door, if flag stones have a moveable flag. Dig deep and put in concrete walls and floor. Dig a sump in case you have excessive condensation. Around your two acres grow masses of thorn bushes to keep people out. Search the web for Underground Bunkers and plans. Cover your entrance with a rug to conceal it. Kenneth Eames.
