Camp Build

Building a 16×16 platform for the dome

JUNE 30, 2026 · BY PAT

The dome needs something flat and dry to sit on, so before any of the pipe-bending I had to build a deck.

The land is an hour north of Crivitz, about a 4-hour drive from home. I bought it to have a spot to be in nature, camp, and mess around building things, and the dome is going to be the permanent shelter up there. But the spot I picked for it is nowhere near level, so step one was a platform.

I went with a 16×16 square. Pressure-treated everything, sitting on concrete piers instead of a poured slab. Piers because it's easier — no mixing bags of concrete or waiting on a truck an hour past Crivitz. You set the piers, shim them level, and build on top.

Flatbed truck delivering lumber to the wooded site — It starts with a pile of lumber dropped at the site.

Then layout. String lines and a tape to get the square actually square and mark where the piers land. This is the part where a second set of hands would've been nice — running a tape and string lines solo is slow going.

String lines and batter boards marking the deck footprint — Squaring up the footprint before anything gets set.

Cleared site with piers set and a tent in the background — That's my tent back there. I camped on site the whole build.

Piers set, then the perimeter beams and the joists running across them.

Floor joists spanning the pier foundation — Joists in. Carrying and squaring 16-foot boards by yourself is awkward; you move slow and it comes together.

Decking goes fast once the frame underneath is right. Getting the piers level first is what makes that possible.

Five or six days, solo. Lumber ran about $1,500.

Finished deck with the dome base outline chalked on it — I set up the dome footprint to get an idea of where to start building the risers.

A 2V dome doesn't sit on a square. Its base is a many-sided ring, so there's some deck left over around the edges that I'll figure out later — bench, storage, wood pile, something. Next up is the actual dome: bending 3/4-inch conduit into struts and seeing if my math was right.
