Mr. Turner's House is the place where Mr. Turner lived when he was a kid.
Mr. Turner's childhood home is located in Dimmsdale, but is not the same house as the Turner's House in later years. It appears in the 1970s, but only the backyard is seen.
By looking at the house it has the style of seaside houses. The house has a second floor, although the interior of the house is unknown. It was only seen in an aerial shot from the back, focused on a tent that Timmy Turner and his child-aged dad had set up.
In the episode, "Father Time!", Timmy Turner used his Time Scooter to travel back in time, after he had melted his father's prized childhood trophy he had won in a race. Timmy hoped to sabotage his father's efforts to win the race, but when he succeeded, the results turned out both bad for him and the entire world. The house is seen twice, once when Timmy and his father are camping out in the back yard and Timmy is telling his father scary stories to keep him awake all night; and then later, when Timmy returns to fix the mistakes he had caused earlier. No other information is revealed about Mr. Turner's childhood home.
