Tanzanian Eco-Village
The images here are from our stay at the Eco-Village in November 2018; Alan Clarke, Adele Mills and Andy Simmonds joined our clients for a memorable few days on site. Key purpose for the visit was to study the test building built that year; install monitoring equipment in this building and existing orphanage houses; carry out site survey and investigate ground water level; determine specific site for future projects. Next building planned is a new house for 10 children and carer to live in – more will follow this first prototype. A school is planned for future years. The site is a 40 acre plot approximately 1 hr from Dar-es-Salaam.

After debate on pros and cons, it was decided to demolish the bungalow and build a near-Passivhaus two storey dwelling. This choice gave the chance to place the house to allow increased solar access...
