Birmingham's Church of Scientology will open in Moseley this afternoon, ten years after the building was acquired.
Pitmaston House was bought by the Church for £4,200,000 in 2007.
Ten years on and renovations have finally finished, with the property transformed into a place of worship for the often controversial religion.
The current building was built in the 1930s on the footprint of the original Pitmaston House - which dated back to the 1870s.
In 2003, the former deal Benefit Offices received the status of a Grade II listed building – protecting both the interior, exterior and setting of the building.
The original plans to renovate the Birmingham building were met with controversy - with one objector calling the church a “corrupt, sinister and dangerous cult”.
Roger Godsiff, Labour MP for Hall Green, had previously said he was "not a fan of the Church of Scientology, which is essentially a money-making cult".
This has been strenuously denied by the US-founded church, which says it is a legitimate religion - something that was backed by the Supreme Court in December 2013.
