UPDATED. Please try downloading again and let me know if they work now. Thank you!
These lots have a swimmable pond but no house for those who want the pond but like to build their own houses.
Pond One costs $7,387 dimensions 2X2
Pond Two costs $12,720 dimensions 3X5
Pond Three costs $19,432 dimensions 4x4
Hope you have fun with these in your Sims 2 game.
EDIT: If you are having any problems with the stairs in these lots...I have found the stairs here. You will need to scroll down to see the stairs and the instructions for installing them.
