Stove?, I need a bigger kitchen... Options

[wings]

Am I the only one who things the furniture placement in this game is wonky?
Heh, wonky.
Still, all the red area really chaps me.
Heh, chaps.
Mmkay, I'll stop. (:

Anyway, I've decided that I've delayed making rainbows long enough, and so I've collected everything for the first one except for the good herb fish.
So I bought a stove.
Except, it doesn't fit anywhere in my house. All the free area is red.
Is it supposed to be like that, or am I missing something?
Like a house upgrade for more room?
I'm currently at hilltop level 2.
Stupid question with a common-sense answer, I know. D;
But I'm just not that talented.
So, help?
Please and thanksssss. <3
