As i can recall this have been really easy to achieve in previous versions of the sims.
Roof objects without floor tile sims 3.
Modding floor tile.
The living room downstairs is supposed to have ceiling heigh all the way up to the roof.
In that case the game would possibly not recognise the floor being a roof and sims will most likely get a negative moodlet for having weather in their house.
This means that gazebos conservatories and other similar areas can also be added easily just don t use foundation tiles.
This isn t even a cheat.
Fences with gaps for paths or stairs help make the roof and decks usable without adding to your tile count.
Instead place flooring directly onto the ground or roof.
You can freely place that chair toilet or statue anywhere.
To add a flat roof to a building you will need to add an empty room on the upper level.
Using the half gable tool place a roof along the thin outer edge of the second floor.
This room needs to be the shape and size of the desired roof so you may need to combine several empty rooms together.
It s just a built in feature of the game that a lot of people have missed.
Settings for 2 sided doubly sided by niol mts2 the 1st approach can have the ceiling lit like how objects are lit in game.
Gambrel or barn roof.
So if you understand how i mean no room on top of it.
Visible ceiling tiles version 3 0 by jgwhiteus mts2 modified floor tiles.
However the ceiling cannot be curved unless curved meshes are made for this purpose.
With the advent of sims 3 pets barns are becoming a common sight and the roof is easy enough to make.
Using flooring as a roof could however cause problems later on if ea ever introduce weather to the game.
If you purchased a digital version of the sims 3 base game expansion pack or stuff pack from origin your game is automatically registered to your account.
If you hold down alt while placing an object in your sims home you ll no longer have to conform to the grid system that s imposed on the game.
Once there is a room on the upper level you can add floor covering and a wall trim to the outer edge.
But now i had a really hard time removing the flooring on the second floor to get the open space i wanted.
Start with the walls of your barn then go up a level and add another set of walls but make this set one space in along the sides.
