London Taxi Tour is reporting that new sets are being built for Half-Blood Prince outside Leavesden Studios.

New for April 2008 is an update on the filming taking place at Leavesden Studios for Harry Potter And The Half Blood Prince. We know they have filmed Dumbledore’s death and the Quidditch has also been filmed, which might explain why the cranes are now gone. We also know that the Malfoy’s house is under construction.

You can see pictures at the link above!

Thanks to Jen for sending this in.
