Add this to the category of unique homes. Called the "Magic Mushroom" house built by LSD. Hugh Heffner had a pajama party here and Andy Warhol also spent time here. It's no wonder. Take a look at this home in Aspen, Colorado that some call a 1970's counter-cultural design. Lots of rock and rounded walls.
Pretty unique and may define the 70's, but I can't really picture the Brady Bunch living here.
