I read a book years ago about genetic engineering changing everything with houses that were actually engineered trees, things called fawns that took care of the house and watched the baby, a thing that looked like a table but I think it was a cop or a soldier. I would like to read it again but I don't remember the title or author.
I think the book you're looking for is Copernick's Rebellion by Leo Frankowski.
Heinrich Copernick and Martin Guibedo came to the States as penniless refugees after World War II. By 1999 they had made huge fortunes in the field of medical instrumentation. But Heiny and his Uncle Martin weren't just filthy rich, they were also the world's best gene engineers. And their latest inventions could free Humanity from want and oppressive governments forever. At least, that was the plan. Imagine: Free homes with all the furnishings and utilities! Free food! Even free babysitters! Heiny and Uncle Martin even thought they should give their inventions away. Free. That's when their troubles began.
