I was JUST THERE in February. At least they saved some of the graffiti walls. From The Journal of Ireland:
WINDMILL LANE WAS demolished over the weekend. However, some parts of the graffiti walls were saved.
The Windmill Lane studios are iconic thanks to a host of musicians who recorded there going back to the 1970s.
Van Morrison, The Rolling Stones and Sinead O’Connor are among the famous acts but the studios were best known for recordings carried out by U2, especially the Joshua Tree album.
