If an architect didn't take gravity into account while designing a structure, there's a good chance that structure would: 1 Fall down 2 Catch on fire 3 Sink slowing into the ground 4 Be blown down by wind

1. Fall Down

Explanation: In one world I've developed, the local surface gravity is slightly more than three times the surface gravity on Earth. Humans settled this world and were doing quite well through highly advanced technology. A series of disasters removed that technology and even the knowledge of that technology. More than 800 Earth-years later, civilization has started to regain a semblance of Western civilization on Earth.

Gravity introduces a lot of stress on structures and, with a gravitational factor like my world, may be the primary motivator in design. While I generally gloss over the specifics of cities and structures, I would like to know the following:

1. What are the best (known) building materials for a high-gravity environment?

2. What are the best architectural constructs for a high-gravity environment? (e.g., arches, peaked or flat roofs)

3. Considering the safety concerns and additional stressors, is ornamentation a viable feature for structures in a high-gravity environment?

i am 100% sure the answer is popular!
