## Examples

***

> Create `building_name.lua` inside `no-housing/config/shared/buildings/shell`

```lua
Config.Buildings.Shell.building_name = {
    shell = `shell_model`, -- model of the shell
    radius = 20.0, -- furniture radius
    coords = vector3(0.0, 0.0, 0.0),
    doors = { -- inside door offsets
        {coords = vector3(-1.4218, -1.9719, 2.9), h = 1.95}
    },
    realestate = {
        label = "Trailer",
        price = 15000
    },
    onEnter = function(ctx)
        
    end,
    onExit = function()
        
    end
}
```
