126 Conch Street

The Treedome is Sandy Cheeks' place of residence. It is notable for being the only place in the entire ocean that Sandy can live in. Its most notable feature is the powerful, nearly-impenetrable airtight polyurethane dome that surrounds it, letting no water seep in, allowing Sandy to survive without her pressurized suit. Despite this home being on the same street (and one home next to SpongeBob's, similar to Squidward's home), it's never seen directly next to the pineapple home, or even anywhere near a street, for that matter.
