It comes after An Bord Pleanala directed developers Chartered Land to remove the proposed ‘park-in-the-sky’ roof garden and to make major changes to the design of the 5.5-acre complex on O'Connell Street before it makes a final decision on permission. The board last week wrote to Chartered Land, controlled by developer Joe O'Reilly, seeking 16 significant modifications, which must be submitted before November 2nd. A spokesperson for the company said the letter "set out a list of concerns". “We now need to work out satisfactory solutions to answer those concerns and to ensure that the Dublin Central scheme can ultimately achieve planning, and progress to development. “We have already started discussions on how best to do this with our advisory team," the spokesperson added. Chartered Land was originally granted permission for the commercial and residential development by Dublin City Council last December. The decision was then appealed to An Bord Pleanála, which held a public hearing on the development in April. The application proposed to create a mixed-use development of 125,000 square metres on the site bounded by O'Connell Street, Parnell Street and Moore Street, and include a “park in the sky”, a John Lewis department store, 98 shops, 64 apartments and 2,868sq m of office space. It also proposed the relocation of two protected structures; the 19th-century O’Connell Hall, and the facade of the former Carlton cinema and the insertion of a new plaza on O’Connell Street. While the letter imposes a significant scale back of the overall plans – chief of which is the omission of the “iconic” 35-metre structure topped by a sloping public park - it does state that the site is “general suitable for the type of development proposed”.
