Out here, you will find plenty of chairs, a large parasol, an outside electric double socket, dining table & chairs, and a storage box to keep things in.
To get outside from the office, you will find the key on the hook to the right (hidden under the headphones...).
When you put the key in the lock and turn it, you have to turn the handle virtually upright to open it, as it has a double lock.
The storage box is up on the top deck and has cushions, little tables, rain covers etc.
Please put everything back, before leaving George House.

There's a little 3 step ladder in the office (or somewhere else, perhaps under the stairs. These things get moved.)
Use it to pull off and put on the parasol cover. It's safer!
Turn the lever to put the parasol up and down, obvs.

If you wanted to open both doors, there's latches on the end of the frame of the left door which let you do that.
When locking the door, you'll have to close it and lift the door handle vertical again, or the key won't go round to the lock position.
