US-based exhibition design company Thinkwell has been appointed to design the Harry Potter visitor attraction at Leavesden Studios, UK.

Although exact details of the attraction are to be revealed, Thinkwell said the site will give the general public the ability to tour several of the original Harry Potter film sets.

The studios, near Watford, Hertforshire, were acquired by Warner Bros in November last year (2010).

Shortly after, the US-based film giant said that it would spend £100m (US$160m, €116m) in developing the 170-acre site, which it has used to produce all eight Harry Potter films as well other hits films such as The Dark Knight and Inception.

The group has secured permission for its development plans from the Three Rivers District Council. Warner Bros. Studios, Leavesden, will open in mid 2012.
