I do so love rammed earth construction.  (So much so that it was one of my first Architecture Monday posts.)  Something about it exudes warmth for me, often coupled with a delightful tactile roughness along with the beauty from the colourful striations.

So that I love this office in Paraguay is no surprise.  Made with reused formwork, recycled glass, and encircling existing trees, what would be a box is otherwise twisted into a spiral to enclose the office, kitchenette, toilet, and, of course, the trees.  Cuts in both the walls and ceiling let in plenty of light to splay across those rough walls to create a lovely play of shadow that changes throughout the day.

Basic in form, this is a great example of how wonderful space can be created without breaking the bank.  All it takes are deft hands and minds, care, and a desire to build something beautiful.
