Hi Maggie
I don't have exact measurements of gardens, but I do know that Evemarina are not planning to lay grass or anything.Sizes do vary by the way - i.e corner units are much bigger.
You will just be handed the garden in it's current state. This is what happened also with garden apartments in Augusta & St Andrews buildings in phase 1.
I know that some owners are planning to lay tiles instead - in order to keep it as low maintenance as possible.
Kind Regards
Jean
