Developers have withdrawn their plans to build hundreds of homes on the former tax offices site in Llanishen.
In March this year plans were put forward to knock down the tax offices on Ty Glas Road and build 250 homes there, as well as 70 retirement apartments, and a 70-bed care home.
Then in September, Cardiff council revealed plans to build a new high school and a special school at the site to meet the rising demand for places in the area.
Now Cannon Capital Developments Limited have withdrawn their homes plans, and have sold the site to the council.
The offices at Gleider House, built in 1968, were home to HMRC offices for decades, but have been left empty since the move to new offices at Central Square in the city centre.
The council’s cabinet signed off plans to buy the land on September 23. It’s unclear when the school would be built. But demand is rising in Cardiff for both secondary school places and places for pupils with special needs, as thousands of new homes are built on the outskirts of Cardiff.
Councillor Sarah Merry, cabinet member for education, employment and skills, previously said: “Cardiff has seen significant investment in its schools and education provision in recent years, but the demand for places across the primary, secondary and additional learning needs sectors continues to grow.
“This land investment opportunity could help Cardiff deliver on its commitment to invest in its education estates and future-proof education provision, helping to meet the projected demand across the city.
“In time, this would assist the council in continuing to provide inspiring, sustainable and community-focused schools, in which children and young people can achieve their potential.”
