Awesome!!!

Wow! Very futuristic! I like it, especially the inside of the building! Thanks for sharing!

Love it! It's so different!

Very creative!

Thanks for the compliments folks. Had this UFO for some time. Made last minute changes on the roof and removed custom content prior to uploading.

You know, if you took away the columns it would float.

Superb design, thanks!

Roundness . . . I don't know how you did it, but it looks amazing. Congratulations on a very creative lot!

This lot looks like a way cool tourist attraction! I know I'd want to visit.

Thanks. Roundness works with round roofs. And large lots, lol.

Haha, that's a crazy lot. It looks very cool!

Wow! Wish my house was Like that haha

Very very creative and impressive, the placement of the walls must have taken awhile!

Well, the outer rims, yeah. The inside is pretty much symmetrical, so thankfully it was easier.

Thanks! It's so creative!

Sure thing, Tvarja. You're welcome.

I turned it residential and love to live in it! Perfect, beautiful!!!

I've made my share of "round" houses, including a Sims2 version of this one, and I have to say the outside walls are easy. It's just a repetitive zig-zag pattern. Time consuming, perhaps, especially several floors high, which probably meant you built the walls from the ground up, but not particularly hard.
That said, I know what was really hard - the roof. Correct me if I'm wrong, but you CFE'd it at ground level, right? Maybe laid out a pattern on the ground?
I tried that once and, yes, it was hard. There are many clicks to be counted - hundreds, if not a thousand or more, who knows. Mine was nowhere near as big as this and I gave up on it eventually. Just wasn't worth the effort for me.
Unless you did it differently.
And that dome in the middle as a finishing touch looks good. It's hard to find an aesthetically pleasing use for those ugly domes.

I also agree with a previous poster that the columns detract from the overall effect. Three really large columns made from wall sections would probably look better, but maybe you ran out of wall sections - that happened to me once.
Anyway, heck of a creation.

Hi ScaryRob,

I did not use the CFE cheat in order to making the wall & floor areas. The three-floor columns helped to make that 4th floor area.

I made the round look using those columns. Then laid out the floor on the 4th floor. Then placed the walls.

I didn't think about making walls as columns at the time (at least I don't think it ever crossed my mine).

Excellent lot, thank you! Will work great as a "mother-ship". :)
