For my adventure yesterday, I visited a rl/sl home builders showplace. When I arrived I was pleased to see designs I liked. Not the ones I had expected, but some very interesting and modern homes. Since you can buy the plans in rl, they are made to that scale instead of the massive room and interesting shapes that you find in most SL homes.
I did not take any pictures as I was unable to contact the architect and make sure it was ok with him for me to publish some. I do hope that you will visit his very pleasant virtual neighborhood.
If you would like to visit, here is the Slurl for Crescendo Design. Take a stroll through some houses that are built with the earth in mind.
