I raised this same question on Reddit.
Two people over there pointed out that the website was actually selling pants instead of LEGO.
So I just tried to access the website through https://hide.me/en/proxy.
When I use their Dutch proxy, the site can't be loaded at all.
When I use their American proxy, the site is shop for pants.
When I use their German ...
These scammer websites have been popping up for over a year on facebook.
Any money sent is lost. You will not receive even a Lepin set.
Use your common sense, how is this website supposed to make money with those prices?
Take pictures of your building, of as many sides as possible
Take measurements or find blueprints of the building. Length, width, height, height between floors, size of balconies etc.
Convert these dimensions to LEGO dimensions. For this, figure out the scale you want to build in first (e.g. 1:40, which is "minifig scale" - but check out this post for some ...
I ordered a couple Star Wars sets from one of these facebook ads, and I was eventually delivered the sets. I was very suspicious at first, but the same ad was still showing up after a couple months, so I decided to risk it.

As the person who maintains the standard, I should probably start by apologizing for not trying to do more to make something like that available.

Xingbao reproduces standard LEGO elements for their models, so it should be much easier to replace the missing parts with LEGO pieces, then trying to contact Xingbao. If you are not familiar with the LEGO equivalent of the missing parts, you can post a picture here, and the community here should be able to identify them for you.
Most real-world buildings will have one or both of the following features:
Load bearing columns - in tall tower blocks you'll often find the lifts, emergency stairs, etc form a central column that the floors can be anchored to.
Supporting beams - these are typically steel beams that travel from one load bearing wall to another, and the floor will then rest ...
Extra support in form of pillars/walls underneath (remember that also weighs something and as such should be supported) is one (and probably the most widely used) solution, another would be to build the floor thicker, and depending on how weak the floor is and how much it has to support yet another solution might be to just not care.
At certain times of the year (particularly at the start of the new year) LEGO release new sets and at the same time remove older sets from their inventory.
Also, in November and December in the run up to Christmas LEGO investors may take advantage of the increased demand by raising prices. Parents buying presents for their children would perhaps bid higher ...
