1.  The easiest route to find is:
From the platforms, take the ramps down to the subway.  At the bottom of the ramps, turn right along the subway.  At the end of the subway turn left up the slope and keep going for about 100 yards/metres when you'll find yourself in Darkes Lane.  Not so much a lane, more a shopping street.  Turn right along Darkes Lane.  At the traffic lights after 300yard/metres, turn right into Mutton Lane.  Elm court is about 400yards/metres on the right hand side of Mutton Lane.  Or better still get a copy of the map.

2. A quicker, but more difficult to find route is:
From the platforms, take the ramps down to the subway.  At the bottom of the ramps, turn right along the subway.  At the end of the subway turn right up the steps, then head diagonally across the car park for about 50 yards/metres when you'll find a narrow path.  Follow this, and at the end turn right into Laurel Avenue.  Follow Laurel Avenue, including the left hand bend until you reach Mutton Lane.  Turn right into Mutton Lane.  Elm court is about 200yards/metres on the right hand side of Mutton Lane.  Or better still get a copy of the map.
