The First Steps of 1V13: HYT’s showcase One Village at a Time project!

Posted on October 2nd, 2018


HYT’s 2017 Ashden Award brought the charity’s work to an international audience. Committed to spreading sustainable Interlocking Stabilised Soil Block  technology far and wide, the Trust will now use the £10,000 award to fund a showcase project.

ISSB is an environmentally friendly alternative

HYT is committed to youth empowerment, protecting the environment and improving educational infrastructure.




Uganda’s young and growing population demands a huge number of schools, many of which struggle with funding and overcapacity. Using environmentally friendly technology, HYT aims to fill gaps in funding, manpower and expertise to address the issues faced by schools throughout Uganda.




The Interlocking Stabilised Soil Block: inorganic soil, 6% cement and manual compression. 



The Interlocking Stabilised Soil Block (ISSB) is the technology at the core of HYT’s work. It’s a robust, attractive and affordable building material which avoids the deforestation and high carbon emissions of the conventional burnt brick.




The Chosen site for our showcase project: the beautiful Kawolo Primary School



How does HYT choose a school to partner with?



There are a number of factors considered when isolating one school out of many hundreds. The process starts with data collection, HYT casts a wide net by surveying many schools.


The surveys provide a wealth of data and allow our team to recognise schools with a particular demand for new facilities. Key considerations are:


  • The numbers of children per classroom
  • The ratio of pupils to toilets
  • The distance to a water source
  • The time pupils spend collecting water
  • The monthly water bill (if any)
  • The number of boarders and staff accommodated on site
  • Kitchen facilities
  • Water, sanitation and hygiene



Temporary kitchen structures in schools use firewood inefficiently and create smokey work environments for cooks



This kitchen was built using HYT’s carbon saving ISSB technology equipped with energy efficient stoves. The carbon savings will continue long into the future as the stoves require less firewood per day to meet the school’s needs.



Many schools construct simple wooden classrooms to create extra capacity.

HYT strives to give children the best possible learning environment



Feedback from this initial phase narrows the search. Kawolo Primary School stood out as their 220 pupils are crammed into shared classrooms, the monthly water bill is exceptionally high and teachers have been displaced from their housing to accommodate male boarders.




Kawaolo P/S is beautifully kept

Many families located near Kawolo Primary school have to send children to schools further away due to overcapacity.




The Partnership



The next stage is the visit: meeting the school administration and testing the soil to ensure it is suitable for ISSB, luckily Kawolo’s soil was perfect!



School staff, members of the Municipal Council, the Richard Feilden Foundation and HYT meet for initial discussions.



One village projects are a partnership between the school, the local community and HYT. The school and community provide secure accommodation for HYT masons, ensure construction equipment is stored safely and provides three meals a day. The partnership gives ownership over the project to each stakeholder group and encourages maintenance of structures long into the future.

The Kawolo school administration, led by Headmistress Florence Wauyaua Luziuda, have been incredibly receptive during the initial phases of the project. The school is beautifully kept, and it has been a delight to meet both staff and pupils.


The Richard Feilden Foundation



John Cleverly of the Richard Feilden Foundation introduces the stakeholder engagement exercise.


This project is blessed with an added partner: The Richard Feilden Foundation, a charitable arm of the international award-winning architects FCB studios. They contribute expertise, creativity and a fierce pursuit of innovative design. Last week John Cleverly, a representative from the foundation, led a stakeholder participation exercise designed to spark the creativity of staff and pupils to enhance the school’s learning environment.



Pupils and staff got in the spirit of the exercise



All parties are extremely excited for the project to progress. As a showcase project, HYT is determined to deliver exceptional structures which meet the school’s needs and act as advocates for ISSB technology.
