Empty buildings in the Jomtien Complex

[Londoner]

I am intrigued by the empty buildings in the JC, some of which seem to have been slowly deteriorating for many years, although the ground floors have flourishing business premises. Since Covid, new businesses- bars and restaurants- have sprung-up near Dick's and have made the area more vibrant while a couple of these huge buildings remain ugly and unused. With all  the new buildings in the area, why so?

Then there's the newly decorated and renovated (post-Covid) three story block- seemingly apartments- directly opposite The Agate-  which remains, as I can discern, empty. Any explanations as to why this is?

Apparently new businesses are coming to the complex... This was posted in a Facebook group. The sign reads "What is going to happen here?" and is attached to the building next to Candy Bar.
