The Sims Freeplay- Adding Basements

Once you complete the Basement of Kings Quest you can build a basement under your houses, this post explains how to add a basement and all the ways you can customise it!

NOTE: you will not be able to resize a basement or add more rooms until you have completed the quest


Building a basement

Building a basement is a lot like building a room except it is underneath your existing house. You can build the basement anywhere inside the grid area (unless there is a pool above) even if it is larger than the rooms above.

The second orange tab in the house section of the home store is basements. Hold and drag anywhere on the ground to build a basement. Green means the room can be built.


The white dotted lines show you were the rooms are above (the blue line is the outline of the pool):


Drag the white highlighted edged to resize.

What is the cheapest basement? A 2×1 basement will cost S8,000

Adding Stairs

You need to add stairs to the basement to be able to access it. The red areas as shown in the picture below show you were items are on the floor above so the stairs cannot be placed there:


If you want to place stairs somewhere you can’t, you have three options:

    1. Move items from the floor above so you have room
    2. Choose smaller stairs or an elevator that may fit
    3. Build another room in a clearer area (outside the house space so you can access the basement from outside)



Decorating the basement

You do this the same way you would decorate a new room

Deleting a Basement

While on the basement tab click on the basement room you wish to delete and select the red simoleon symbol to sell it. You can delete basement rooms even if there are rooms on the floor above.

For more details you can watch my video, Building Patios, Balconies and Basements:

please read before asking

How do I start this discovery quest?
Once you have completed the balcony quest you need to wait 24 hours then you can find Bree (the woman in the hard hat) in the park to start this quest

Why can’t I do this discovery quest yet?
You cannot do more than one discovery quest at the same time, if you are currently on another one (the list can be found here) you will not be able to do this one until that one is completed

Can I do discovery quests at the same time as a main quest?
Yes you can

Do I have to do this quest?
If you don’t start the quest you don’t have to do it at all but if you have already started it you need to complete it before you can move on to the next quest

I haven’t started this quest yet, will it still be available when I want to do it?
Yes it will be, you can choose to start it whenever you like

How do I call a cab to the DIY house?
Using a phone

Is it possible to complete the goal to play with a pet if I don’t own a pet?
No, you will need to build the pet store and buy a pet to complete this goal, it cannot be done at a neighbours

What pets can you use for the play with a pet goal?
Adult dogs, cats or dragons and kittens and puppies can all be used now

Help! Bree is stuck in the middle of the table
Try restarting your device, this should fix the issue

Bring food to Bree gets stuck at 100%, what should I do?
You may have to use 1LP to complete this task

How much does it cost to build a basement?
The cheapest is S8000 for 2×1

I had all sims leave the DIY home but it didn’t complete the goal, why?
Try and have all your sims not doing any action, this sometimes makes the game recognise you have completed that goal

What do I get if I complete this quest in the time limit?
The DIY Home

What happens if I don’t complete in the time limit, can I still finish this quest?
Yes you have to finish it to unlock the ability to build basements before you can move onto the next quest

I didn’t complete in the time limit, can I restart the quest?
No, you cannot redo quests

Can I still get the prize if I don’t complete in the time limit?
No, the only way to get the limited time prizes is by completing the quest in the time limit

I don’t like this quest! Can I just skip it?
No, you have to complete this quest before you can move onto the next one now that you have started it, if you don’t start it you don’t have to do it

Some times are slightly different on my game, why is this?
Times may vary depending on the star rating of the item you are using, as the higher star rating an item has the quicker you will complete a goal

Some times are really off/ different goals show for me, why is this?
This will be because the quest has been updated recently, I try my best to keep these posts up to date but it is difficult as I cannot redo every quest each time the game is updated. If you notice any changes please let me know so I can update the post
