The materialwhat this method is built from
The method, plainly

Fired brick bakes the climate cost of a building into its very walls. The compressed earth block does the opposite - it borrows the ground, presses it, and gives it back at the end.

Because the block is made where it is laid, transport all but disappears, and the wall keeps the soil's natural ability to breathe and to even out the swing between a hot day and a cool night.

Why we reach for it

Up to ~10-15x less embodied energy than fired brick (indicative)
Made on site - almost no transport carbon
Breathable walls that buffer heat and humidity
Returns to the earth at end of life

From ground to wall

how it comes together

A few unhurried moves, in the order we make them.

01
Test the soil

We sieve and test the site's own earth for clay, silt and sand balance before a single block is pressed.

02
Stabilise & press

A small dose of lime or cement and a manual/hydraulic press produce dense, uniform blocks that cure in the open air - no kiln, no fire.

03
Lay & leave honest

Blocks are laid in an earth or lime mortar and often left exposed, so the wall reads as exactly what it is.
