Over the Christmas I went to the UK and bought building supplies for the project to be sent back to Japan by shipping container. This was after months of researching on the Internet various options that would help realise the aim of building a low impact house. Although of course there would be a carbon footprint attached to the shipping, most items were either unavailable in Japan, with no Japan made equivalent or just too expensive. As an example of the former; external doors that are highly insulating. Items that were prohibitively expensive in Japan, and ultimately, in most cases, made outside Japan included triple glazed skylights which are about three times the cost and come from Denmark.
So price, cost, and quality were the basis of the purchases. Items which could be bought in Japan have been – such as Japanese wood cladding. Other items included paints with very low or zero volatile organic compounds – or VOCs i.e. formaldehyde, Super Quilt insulation for the roof, walls and floor, water butts (collectors) – up to 10 times cheaper!, and wood burning stove.
In addition to the link Key Features, later posts will also give more details on why these were chosen but als always any questions or comments about them would be greatly received.
Here are photos of the container arriving and being unloaded
