In order to get to Life Yard, you need to do the following.

How to Enter:
1) Go to Redbrick Courtyard
2) Go to the bottom of the room
3) Walk to the far right 'door'
4) Enter on the far left side of the door


It's pretty complicated... Even harder than it sounds... But you'll get it eventually if you keep hanging around the bottom of Redbrick Courtyard.
