This is a good build. I'm not sure if i remember all the details of the Spongebob's house, but this looks really good. And i think this pineapple need to be with a less bottom (where dooor are is, on this level), like in the cartoon. For example:
XxxX

\ __ / <--- This what i mean.
Btw, i still think i'm not sure on this part of build, but i think the pineapple a bit drowned on the ground and it also have a more yellow color (where's the door are is).
Anyway i like this so much and i give you my 9,9/10 rating for your effort.
