In the beginning (around 2015) Bruce played with cardboard shapes.
This may not be a legimate way to originate a building.

The form of the building was born by playing with cardboard.

By 2018 it had advanced to scaled drawings. The structural engineer declared "too complex" and sent it back.
On January 30, 2019 we submitted drawings for a buillding permit.

A 2018 iteration, more complicated than succeeding revisions.

The building location must compromise several considerations. It may not be too far from the septic tank. It may not be too close to the slope. It must not be too close to the great redwood.
As soon as the application was submitted, another constraint was added by the county. The building must be at least 75' from the centerline of Nash Mill Road.
The perimeter is rather complicated. I had to shift it multiple times before and after permit application.

The building perimeter was hard to lay out by rods marking corners and pipe scraps marking walls.

At last I made a rigid frame that mimiced the perimeter to ease position tweaks.

The drop from building footprint to septic tank is barely enough. From 2018-2019 I measured it by various means - liquid level, laser level, LIDAR scanning. I determined the only route that could work went beneath the "Tower Bath" building, completed in 2014.
The whole length of the drain pipe I connected and supported to assure it would work.

Its path passed under and through a lot of heavily used vicinities.

The exterior will be all metal. This is a wildfire-prone locale. In a huge US Steel scrapyard a mile from where I grew up I inspected beautifuil rusting sheet metal (and was chased away by staff.)
