If there is a covenant to protect the area, which is a natural beauty spot in London (the next high hill is Hampstead Heath), with the Horniman Gardens and the nature reserve nearby, that covenant should be respected. There is also a covenant with the TLRA association to which members should adhere. This may require that no commercial activity of large dimension should be opened in a house thus destroying the character of the area (we talk here of an expanding business). So far the covenant has always be respected and considered adequate for the area. Why do we want to change or abrogate it? The nursery is not an activity run from a bedroom by one person on his/her computer or someone working from home for his/her employers or in the shed. It is not an EBay selling goods activity, but a fairly sized enterprise. All sentiments on this issue are from people who do not live in the area and cannot appreciate its surroundings.
I have friends living in the area and often visit them. It beggers belief to see children walking to/from nearby schools, throwing sweet bags, chocolate papers ,coca cans in other people's gardens. My friend is scared to say anything, in case they throw stones instead. Now the nursery under scrutiny is for small toddlers and babies, but what about if it becomes a private primary school in the future?
