In a statement, Din l-Art Ħelwa said it believed this over-sized development would have a devastating effect on the Maltese landscape and the daily lives of many people.
“The Planning Authority has ignored the concerns of the public. This is unacceptable, especially for such massive projects with huge and permanent damage to us all.”
The 38-storey Town Square skyscraper will be sandwiched between existing homes and shops.
“People who visit, work or live in the area will face terrible traffic and parking problems, and neighbours will be deprived of sunlight. Its promoters have ignored or downplayed the difficulties and inconvenience that the project will cause for the entire Sliema community,” Din l-Art Ħelwa said.
Its appeal is supported by Nature Trust Malta and the Malta Archaeological Society.
