Checking Street View this is correct.  The buildings in the area are all semidetached buildings of the same architecture. A simple split rectangle template copied across all the buildings is needed to number all the houses correctly.

I will do it myself when I have time, but if not you're welcome to do the following.

Make 2 rectangles with the area tool that split evenly across the roof, joined together on the common wall.

Shift click both rectangles and fill in the street information while leaving the house number blank.

While both rectangles are selected, press Q on your keyboard to square the template and right click near one of the outer  corners of the selected areas, and then paste the template on the next house facing the same direction, on the same corner of the roof. (use undo and repeatedly paste until correctly over the roof structure)

Click the rectangles individually and enter the house numbers.
