I read ‘Limits to Growth’ 40 years ago about the absolute necessity of seriously limiting our consumption of resources. I was studying A’ level economics then and it influenced my life direction significantly. It wasn’t until I travelled in Africa a few years later that my views on changing the way we are living became clearer. My interests since then have been determined by taking personal responsibility for this change. I have worked in a workers cooperative retailing wholefoods, studied and practised homeopathy, studied and practised permaculture, worked in joinery, mediation, and ecologically retrofitted 3 houses, undertaking as much of the work as I could. So I have learnt a lot, mainly by doing, and taking on relatively ‘unchartered’ domains at the edge of the relationship between modernity and nature.
My motivation is embedded in my story above. I strongly believe that our problems are not insoluble. We have all the technology and expertise we need already to, for example ,reduce our energy consumption (in the ‘developed’ world) by over 80%. Energy efficiency is grossly undervalued as a proper solution. We are constantly being bombarded with ‘solutions’ which are un-thought out and based on short-term thinking. In complete contrast, retrofitting our old homes is one of the best things we can do for the planet at this point in history.

No more condensation or mould. We now live in a healthy environment, the air is constantly being refreshed without losing heat through opening windows or trickle vent or the gaps between floorboards etc. We are about £1800 pa better off and this will increase with the renewable heat incentive in october 2012 and the rising cost of energy. Draughts have been almost eliminated. We are optimistic about what can be done with older houses because we have done it.
The triple glazed french doors (from Green Building Store) which open out onto our deck. A wonderful extension to our living room in summer.
I have now finished the new building. It is a second workshop for furniture making. It has another wildflower roof, timber clad, double glazed, insulated door and as much insulation as I could fit in; a combination of sheeps’ wool slabs and PU. I have a small oil filled radiator in there which I hardly use. Also last autumn I completed another wildflower meadow building (number 4) to house our electric bikes and the odd garden tool.
Now in march 2013 our first crocus bulbs are appearing on the rooves. I used a wildflower seed mix with about 20 different plants and added a few bulbs last autumn. It is exciting to watch for what comes up. Which reminds me that the frogs and newts are about to re appear in our pond.
Now the house is finished my next adventure is making furniture (mainly) by hand. I am allowing myself some machinery for the milling of the timber before the joinery (more precise) work.
