It has not changed that much at all, a nice thing to see these days. I would love to have a house like that, just drive the car into the front room and give it a quick service whilst watching the telly. I wonder if you would get planning permission these days to n your house into a garage, it certainly looks like this place was once a residential property that was converted for commercial use. Come to think of it, there were once loads of small business's run from converted residential properties, a thing of the past I am sorry to say, now it is all industrial units, a long way from the small, friendly local business at the end of the street. There must have been many scattered about, if you look carefully when out and about traces of these small concerns are still evident from faded advertisements painted on walls.
