The timber-framed building will be rebuilt to the same designs and is set to open in early 2016.
A spokesman for the University of Nottingham told the Nottingham Post: “We can confirm that our contractor has been working on the Jubilee Campus for a couple of weeks to clear the fire debris from the site where the fire took place in September in preparation for rebuild work.
“”We are currently planning rebuild activity and will be making an announcement shortly as to when this will commence.
“The rebuild planning is based on the same design principles and construction materials to deliver a carbon-neutral sustainable chemistry laboratory building.”
The Health and Safety Executive is still investigating the cause of the blaze which broke out at the fit-out stage of the building.
The project is part funded by GlaxoSmithKline and is billed as the world’s first zero carbon chemistry laboratory.
