If one of the spatial dimensions *not* perpendicular to gravity wrapped around, how would architecture be different? [duplicate]

Continuing this question, but with a slight change. In this world, if you go 7 feet east, and then 7 feet up, you would be in the same place. Note that the ground wouldn't be perpendicular to gravity. It would have to be sloped for this to work.

My question is, how would this affect architecture? One thing to note is that although the ground is naturally sloped, you could cut steps into it to make travelling easier (although creatures may not be used to levelness). Additionally, if you made two story house (each story being 7 feet), and went 7 feet west of the first floor, the first floor would be 7 feet below you; you would be on the second floor. How this is connected would have to be addressed.

How big could buildings be made? How would buildings be renovated and made bigger? How would architecture be different?

Note: For the purposes of this question, there is a uniform downward gravitational field of 1G (if you prefer, you may think of it as if there was no gravity, but the entire world was accelerating upward with 1G of acceleration.)

Note: This is different from the linked question because in that question, the wrapped around dimension and gravity where at a 90 degree angle. In this, it is at a 45 degree angle.

• All you really did was change the question by 90 degrees... – bowlturner Oct 16 '15 at 20:23
• @bowlturner And all the novel orthongonal changed was a sign in the spacetime signature. – PyRulez Oct 16 '15 at 21:30
• @PyRulez Nothing's changed. It's akin to rotating the world by 45 degrees and extending the distance needed to come back to where you started (from $7$ feet to $7\sqrt{2}$ feet). – HDE 226868 Oct 17 '15 at 0:12
• @HDE226868 Rotating 45 degrees is huge! Perpetual motion, for example, is now possible. – PyRulez Oct 17 '15 at 0:14
• @PyRulez Why not in the up direction? If this universe is closed, the same should happen. You can't treat the universe like it's on the surface of Earth. There's no preferred direction in the universe. – HDE 226868 Oct 17 '15 at 0:26
