Dear mrbisonm,
Thank you for your response. Indeed, I would like to get rid of the sandstone tiles, replace them by low-wealth grass texture, lose the light and other props like trees in the diagonals. The basic walls with grass would be much more realistic in areas where men wouldn't invest in a sandstone path along the shores.
I had a response from BarbyW on the LEX forums in which it was made clear that, since Marrast embedded the sandstone in the lots it would be impossible to change them.

I'll send you the link nonetheless, even if it was for blue sinjid who really needs them.
I guess you can prove BarbyW wrong by trying to change them anyway. It won't be a disaster if the set cannot be changed. I want to thank you again for your response.
