Hello and welcome to OSM.

Nice try, I understand it’s not easy to get things right in the early days.  I did some minor fixes here.  In particular, this garden is behind a wall, so we cannot connect footways from the road onto it.  (If we do this, routers will assume we can easily get into this garden.)  Don’t worry, all the fixes have been applied and thanks for adding this garden, I didn’t know about it.
