You can move stuff by holding down on the objects you want to move, either on build mode or not.
Also! Did you know that you can make walls different colors in the same room?! And the exterior walls?! Just choose the “Wall” option rather than the default “Room” option while choosing wall styles, it’s in the upper right hand corner when you’re changing the walls.
Actually the right answer is, you can build another house but in the same and the only lot/land you have right now. If you watch a youtuber video, she build 3 house (separately), a very nice design I will say.
Ok this is what I did. I collected cupcakes between 15-20 but more of you want and then chose two days irl where I wasn’t doing anything then when the time came of the first 7 hour quest I used 4 cupcakes to narrow the time then on the second one I didn’t then waited then I saved the 3rd one for when I’m about to go to bed so then I can do a seven hour one then and when I woke up I didn’t use cupcakes on the 4th one then used cupcakes for the rest
