A generally triangular truss, comprising a horizontal chord and a pair of inclined chords. The inclined chords are joined at an apex, and the horizontal chord extends between the inclined chords to form a base of the generally triangular truss. A pair of vertical ties extends between the inclined chords and the horizontal chord, and a horizontal tie extends between the two inclined chords. The chords and ties define therebetween a space in which to construct a living area. The joints between the chords and ties are defined by holes extending through the chords and ties, with the pins extending through adjacent ones of the holes to create pinned joints.
