Organic Architecture, Low Impact Housing or Houses from the Shire

Using naturally found materials in Wales, lots of sweat equity, and a vision of whimsy this house was built for around 12,000 USD and can be used all year round. The reason this shelter works is the following. 

• Dug into hillside for low visual impact and shelter
• Stone and mud from diggings used for retaining walls, foundations etc.
• Frame of oak thinnings (spare wood) from surrounding woodland
• Reciprocal roof rafters are structurally and aesthaetically fantastic and very easy to do
• Straw bales in floor, walls and roof for super-insulation and easy building
• Plastic sheet and mud/turf roof for low impact and ease
• Lime plaster on walls is breathable and low energy to manufacture (compared to cement)
• Reclaimed (scrap) wood for floors and fittings

Sustainable, low impact, and affordable housing for those who want to partner with their local surroundings rather than dominate it.
This is a very cool site with plans and ideas on making your own.
