Where is the Lilac Room?

Many Barbican residents meetings happen in the Lilac Room, but where is it?

It's here

The room is below the podium between the entrance to Lauderdale Tower and the BEO offices.

To enter, head into the Seddon House north stairs (entrance close to the BEO offices) and go down one floor to level 02 and out onto the walkway overlooking Lambert Jones Mews.  Go left along the walkway and the door to the Lilac Room is the first on the left.
