Sustainable Building

At Fazenda Tomati we are passionate about sustainable building and technology. If you would like information on Matis project: Bioconstruction with kids, see her page here

We have a couple more projects on our land which we will need help with. We would like to build two earthbag domes, each 6 metre diameter. We are open to offers to experienced professionals looking for a site to lead a workshop.


We are passionate about natural building and have been practicing it since 2015. In our house we used as many different techniques as we could find space for. Below are a list of the techniques we have used just on our site here in Portugal

  • Clay rendering by hand and with tools
  • Home made clay, wheat and sugar paint
  • Lime render
  • Lime pointing
  • Tadelakt
  • Wattle and Daub
  • Adobe bricks
  • Rammed earth cement blocks (experimental technique)
  • Cob floor with linseed
  • Cob oven

And techniques we have worked with on other sites:

  • Cob structural walls
  • Cob render on reed mat walls
  • Cow poo, clay and linseed exterior render
  • Stone wall with cement
  • Dry stacked stone wall
