Grand Designs - The Underground House: Revisited | Construction and DIY projects | Forums

I was trying to imagine how I'd build an addition last night and I couldn't resist the idea that the best way for me to build would be underground. I want a bunker/master bedroom addition to the house. Still, I don't want it to be a gloomy rat hole, i'd want it to be open, comfortable, and as spacious as a normal master bedroom, just able to provide a few months of underground shelter if absolutely necessary. I wonder if such a thing is possible.

I'd really want it to be about that size, but have no bunk beds. I'd want to move the kitchenette/living area up to the door, then have the bathroom, then a queen sized bed in back. The living area would probably have some convertible furniture to increase the people it could sleep, but I don't want doomsday bunks with chains to the wall anywhere to be found.

Really, I'd like it to be square instead of shipping container proportions if at all possible. I'd also like to use Vic from Safe Castle, but these guys had better pics of finished out shelters that look like liveable space than Vic has on his website. I wouldn't be surprised if Vic could do the same thing though.
