Under the recent "Plasticville" post, I just posted a picture of a a triangular kitbashed
PV station (the captions did not come through), for inside of a wye. Building one from scratch, depending on the type doesn't seem that hard...one less wall to build. Lay
out the floor (ground space you want to cover, make a pattern of that, and use it for
the roof, and to measure the walls around edges).
