NATURAL BUILDING

Urban Cob

The same question, asked of a wall instead of a pot. Traditional cob is clay, sand, and straw. We keep the clay, already a waste dug from the city, and ask whether the sand and straw can be replaced with local waste.

Crushed glass, glass powder, stone and marble dust in place of sand. Recycled plastic fibre, human hair, and textile offcuts in place of straw.

Unfired, at building scale. This is at a very early stage: results are preliminary and nothing here is ready for construction.

Hand-drawn diagram showing the urban cob material system: city waste clay, crushed glass, recycled fibre, and other urban waste assembled into an unfired cob wall.

Tests continue. Open questions remain. Findings published openly.

This is at a very early stage, and there is a lot still to test. If you want to research or build with us, we are open to working with designers, makers, and others on it.
