I fixed the street names. On the North side of the road, there are 12 and 13 New Road. Interestingly, Art Café uses 14 Bonn Square (for convenience? I suspect it originally was meant to be 14 New Road, following the sequence).
I left the names changing at what seems the natural beginning of the square.

I've done some basic realignment too, it should be serviceable for now (but St Peter's area will need more precise work, although current images are very distorted).
