.&.&.&.&.& six square meters. these could be made &..&.&.&.&
.&.&.&.&.. out of various materials such as carbon &.&&.&.&.&
.&.&.&.&.& fiber or plastic, not necessarily the &..&.&.&.&
.&.&.&.&.. same for each floor. &.&&.&.&.&
.&.&.&.&.& &..&.&.&.&
.&.&.&.&.. the house would be hung on a "mast", a &.&&.&.&.&
.&.&.&.&.& ridged metal pole extending between &..&.&.&.&
.&.&.&.&.. fifty and a hundred meters. a mechanism &.&&.&.&.&
.&.&.&.&.& within each floor would enable them to &..&.&.&.&
.&.&.&.&.. climb up or down the mast, together or &.&&.&.&.&
.&.&.&.&.& individually. &..&.&.&.&
.&.&.&.&.. &.&&.&.&.&
.&.&.&.&.& the lowest floor would usually have a &..&.&.&.&
.&.&.&.&.. loading dock, a balcony/front door, and &.&&.&.&.&
.&.&.&.&.& various ladders. &..&.&.&.&
