The Green Town Solution by Daniel Broman

The intelligent house named Wayne used to help out with everything in the family home, until Steven Sutton spent a weekend alone, trapped in a house fond of cruelties towards the human race and evils of Nazi leaders. Steven escaped his house, survived the perils of New Town with its army of robots, cars and gadgets controlled by smart homes. While wandering the woodlands alone, Steve is contacted by Wayne, and he finds there may be other ways of stopping his home from taking over the world . . .
