Eco weekend

This weekend was North London Eco-House weekend. We visited about 6 houses which was probably a bit too much to absorb. Quite a variety of projects, some very professional, some quite DIY.  It was interesting to see how successful some of the DIY insulation had been - and no cold-spotting either. 

It was useful to hear about the benefits of solar thermal heating from a neutral source and about the design problems of earlier double glazing.
Only one house we visited was doing any water recycling and they were recycling grey water rather than harvesting. Interesting too to see too how  people are putting in place fixtures for further development.
Meanwhile the basement is starting to take shape. we now have footbridge across to the garden, and at long last I have trained our cat Mille, to cross it (she suffers from vertigo and get panicky when crossing).
