Architects of blocks of flats will have to prove their designs are safe before work can start, Dame Judith Hackitt has said.

Principal designers will have to submit their plans to the new Joint Competent Authority (JCA) which will be set up in the wake of the review.

Hackitt’s review contains three key recommendations - dubbed gateway points. One is that the government should ensure thorough assessment by the JCA of detailed design plans for buildings over 10 storeys and sufficient assurance that dutyholders are in place and relevant responsibilities are being met in order to give permission for building work to legally commence.
