Roz says "The other issue is surely whether it can be proven that the nursery is likely to be more inappropriate than a Drs surgery or a solicitor. I think of my drs surgery. It contains a few clinics and is always packed. Parking would inevitably be required. ".

I suspect this is a good example of where covenants become out of date over time. There would have been hardly any cars back in the 1930's and and a drs surgery would probably have just been a consulting room with a single GP. The intention of the covenenat at that time, I assume would be to keep the area quiet and business free - with the exception of those 2 professional services.
