Are GC’s able to choose designs?

These became fairly popular just before the last RE bubble popped.

You could talk to a good Agent to ask those kind of like that and where is the most popular space.  

Pretty popular here in Seattle which is an expensive area.  

Using the SFR as an example, I could likely get a 2300 SqFt building with low quality finishes, basic architectural design, etc finished for under $400K ($175/sqft)However, if you had an ultra- high-end, luxury home before; you likely won't be very happy with what that $400k ultimately yields.

The house looks chopped up in blocks because A) it's a terrible design, and B) Nothing picks up cues from any other part of the house.

Basically, use the policy to buy other assets, then you can use the policy (if designed properly) to supplement retirement when you're done obtaining assets. 

That is why CCR is so popular and also why it is not that bad to use as a primary evaluation for an investment.

It depends a lot on how high between your peaks and valleys if is more than say 1/2", most leveling materials are not design to fill in that much.

I have some thoughts on a potential design but thought it might be helpful to get a recommendation from a professional as well (probably designer maybe architect).
