flexible use of simple locally available materials for the building frame combined with zero cost used plastic milk containers for 'brick' infilling


1) basic frame of 7no. timber posts 3m long, driven 500mm into the ground on 3m grid

2) 7no. 3m long caping pieces nailed around the top of the frame

3) manufacturers and users of 2litre plastic milk containers persuaded to slightly alter the design of the container to facilitate a lego type clipping together

4) used milk containers to be collected, filled with water (to provide extra strength), or with blown or pumped insulation foam when this is available (to provide heat retention and/or exclusion, and clipped together to provide infill panels between the upright posts, leaving one single door opening, fitted with a straightforward timber door and a screendoor fitted with mosquito sheeting

5) a barrel shaped roof to be constructed, using the same used milk containers

6) a plastic tarpaulin pulled tightly over the completed structure to provide weatherproofing and additional strength and rigidity to the overall structure

7) the containers and the tarpaulin are translucent so they give privacy but also provide light, so no windows are required. 2 small panels are formed on opposite walls to providea fresh airflow for ventilation and are fitted with mosquito netting

8) as soon as is economically possible, an outside extension is to be constructed in the same manner, to contain a dry toilet

9) spare milk containers to be washed out, filled with water and left in the sun (to kill bacteria), a simple cotton bag is used to filter out any solid particles prior to use for drinking

10) the smallest comercially available basic solar panel to be positioned on the roof (not fixed, so that it can be removed and left inside for security when there is no-one at the property
