It’s always bothered me a bit in The Sims, simply because of that ‘compulsion’ to ensure there are still empty spaces in the neighbourhood view where a lot can be placed.
Above ‘Somerset’ (lot 57) in any case. And according to the game’s own logic, it’s no problem if a lot is cut off from screen. See lot 64 (The Morris Cottage), lot 79 or lot 72.

So what did I try? I copied House100 from House11 into every ‘UserDate...Houses’ folder.
- Edited NeighborhoodDesc.iff: added a new entry to the STRH# with ID #2100 for Lot 100 (success)
- Edited LotZoning.iff: added a new string to ‘Lot Zoning Info’ so that the game treats Lot 100 as Residential (success)
- Edited StreetNames.iff: added a new string to the ‘Lot Assignments’ entry so that the game assigns Lot 100 to a street (Ridge Road). (#100 2) (success?)

That’s basically the end of my “achievements”. In the “LotLocations.iff” file, I added a new string in entry 4 for the Old Town and followed the format used for the other lots there. Unfortunately, however, the thumbnail for Lot 100 doesn’t appear in the game.
Using the ConsoleCommand ‘lot 100’, I can open, edit and save this lot. New thumbnails are then also created in House100.iff.`
Does anyone have any suggestions as to which files still need to be edited?

edit: I tried swapping the lot with an visible one (57) , but that didn’t work either.

edit2: LotFiles in the GameData folder do not appear to be crucial for increasing the number of lots either
