Last week CAT headed to London for Grand Designs Live. We had been asked to provide live demonstrations as part of the ‘Natural Building Methods’ section – an area CAT has some experience in! After much discussion, we decided on glue laminating demonstrations for making arches for a Timber Arc construction. The Timber Arc is a beautiful example of timber frame building, using local and low-carbon materials. It’s also a dual-chamber compost toilet.
Our goal at Grand Designs Live was twofold: provide the public with an interesting demonstration of glue laminating, whilst also raising awareness of different methods of dealing with human waste. Compost toilets are not for everybody, if you are connected to a local sewage system then chances are you will not need to deal with your own waste. However, some off-grid locations mean that people have to be a little more creative in the sewage solutions.
During our time at Grand Designs Live, one thing that kept cropping up again and again was bafflement. People often asked us why we were making a compost toilet, especially one so beautiful. Well, compost toilets can be efficient and practical, resulting in nutrient-rich soil to be used in the garden. They don’t use any water or chemicals, although most types of toilet need a fair bit of room to allow composting to occur at a steady pace. We have several composting toilets up at CAT, working alongside our reedbed sewage system and providing us with fertiliser for our gardens. Furthermore, why not make a beautiful building to house your compost toilet? It’s a place you visit each day after all! We also liked how the idea of it fitted in with the ‘grand design’ aspect of Grand Designs Live.
People certainly seemed to agree with us, judging by the level of interest we received each day. Engaging with people on environmental issues whilst also showing how we go about dealing with these problems was wonderful. Moving people’s thoughts away from bafflement and towards more environmental ways of thinking is key. Hopefully in the future CAT will be able to visit even more shows to keep spreading the word.
