Education Minister Kay Hallahan today announced the go-ahead for a hall/gymnasium at Armadale Senior High School.
Mrs Hallahan said work would start on a new hall/gymnasium this financial year and the existing gymnasium areas would be remodelled into a performing arts centre.
Existing gymnasium facilities were no longer adequate to cater for a modern physical education program, including basketball.
The Minister said attempts to involve the City of Armadale in a jointly funded facility on the school site with dual community and school use were unsuccessful.
"The decision reflects the Government's commitment to bring the facilities of older schools up to the standard of new schools," she said.
"In the Government's education and training blueprint 'Foundations for the Future', $125 million was committed for this purpose over the next five years."
The decision follows a recent $1 million project to provide new administration facilities and a staff room at the school and a 1989 upgrade of the Home Economics area at a cost of $257,000.
Armadale Senior High School opened in 1953 and today has nearly 1,000 students and more than 70 teachers.
