341V: Same Street (??)

Looking for a children’s book about people who live on same street. Each one of them breaks the mold of their boring houses and the end of the street is a collection of fantastical and amazing houses.

Each time someone changes their house, someone says, “He’s popped his top!  He’s flipped his lid!”
That’s all I can remember other than loving the book.

341M: Chapter Book – Childrens’ House Floats Down River

I am looking for a children's chapter book. The plot involves children whose house is able to float and they float down a river on it. This was a chapter book from the 1970’s or 1980’s. I don’t think it was a houseboat but rather their actual house was put on a raft, but my memory could be wrong. Thank you!!
