Tallstar: Quite the improvement. The roof terrace is an interesting idea, however if you want to include actual plants you need to make them look, well, planted.
Try partitioning the area which has the plants with a very small fence, like "monorail fence" or "taboo bamboo." this while section the area creating clear plant areas and walkways.
Then, go to the miscellaneous tab in flooring, and find the "tar and gravel textured floor." This flooring tile looks a lot like dirt, and if you use it on the floor space where you put your plants, they'll look like they've been properly planted in a planter box.
After that's done, place yourc actual potted plants in the brick walk-spaces and around the seating area for a little extra flare.
@ Thomas: gotcha gotcha. Well, look forward to seeing the additions.
@ Anushka: Yes, I'm definitely questioning them as well. it's sort of a fight between they're slightly too short for this particular window, however they have the right amount of "weight" the room needs. I'll see what comes of it.
@ Ausette: Every tile has potential.
Half the fun is finding new ways to express patterns. I'm actually borrowing an idea I got from your last rug of taking a pattern and rotating it around with the triangle to create the pattern in a circular motion.
Here's a closer look at it. Unwittingly it came out with a slightly well worn look, like it's seen a lot of traffic for a lot of years, which inspired me to design the rest of the house to suit an elder couple.
