Initially, the cost of the project, which began in 2015 was estimated at M111 million, but due to delays, the building is currently only 85 percent complete.
At the moment, the cost of the construction is worth M170 million and is expected to continue increasing up to M240 million, the Minister of Development Planning, Selibe Mochoboroane revealed on Wednesday during his tour of the site.
He said the building has taken much longer than expected, an undertaking which has already cost the government a lot of money.
“This building has taken a long time to be completed and therefore costly. Honestly, we have to refrain from this kind of conduct as government because it comes with more spending,” Mr Mochoboroane said.
The project is actually expected to be finalised in October with a few other logistics to be completed within a period of a year.
That means the building can only be utilised after a year from now.
The museum will among others house cultural infrastructure such as art galleries, cultural centres, theatre and film studios, craft centres as well as amphitheaters.
Upon completion, the facility is further expected to have a display area, auditorium, office storage facilities, boardrooms, photographic library and the laboratory conservation among other facilities.
