This beachfront luxury cave home can be modified to have an extra floor and also not be beachfront.
I do not believe in charging rediculous thousands of lindens for homes as i see people do when theyre simple shapes and spaces, this cave contains a natural looking sculptie that shapes it to look very natural and realistic somewhat. The cave requires 1440m of land squared to get out, and is very low prim as it is built for efficiency as well as apparel.
You can see a demonstration of what you can do with this cave, at the following location: http://slurl.com/secondlife/Meari/215/67/134/
It is my own home, and im very happy to share for a realistic, not rip off price. Enjoy!
