@Ididntwanttopostbut Nice find, but you need to include a link in your post. Here is map. Just click 'edit' and add it before mods delete your post https://www.bing.com/maps?q=impact+artists%2c+este+road%2c+London&FORM=HDRSC4

EDIT#1 If you click on the Christchurch link on map link, it takes you to their website which has a map showing a Catholic Grade School in close proximity. http://www.christchurchbattersea.co.uk/contact/

EDIT #2. If you click on the streetside view on the map, you see what appears to be a playground across the street.
