The workshop
Our walls are built by a small team in the forested countryside outside Lublin — the same region where the traditional Guardian Towers (tężnia) have stood for over 200 years. Every unit passes through the same four pairs of hands before it leaves the workshop.
The materials
- Kiln-dried European oak. Grown, milled, and dried within 80km of the workshop. Finished with a natural linseed oil that ages into a soft silver-grey.
- Blackthorn brushwood. Hand-cut and bundled from managed hedgerows. The thorns are what give the wall its enormous evaporative surface area.
- Hammered copper piping. Every fitting is copper — chosen for its natural resistance to brine and its ability to patina beautifully outdoors.
- Food-grade mineral brine. Sourced from the Wieliczka salt basin, one of the oldest working salt regions in the world.
The build
Frame joinery is done with mortise-and-tenon — no metal fasteners in the load-bearing structure. Brushwood is threaded by hand into the oak lattice, then trimmed and dressed so that water flows evenly across every square inch of the face.
Every wall is signed and dated on the underside of the base plate by the craftsman who finished it.
