From article here.
The business environment didn’t justify doing the office development so we asked [architecture and design firm] Woods Bagot to come in and reconfigure the building as a condominium.
And here is the redesign:
“Fortunately it was a single loaded structure, so the core of the building was at the back. It didn’t inhibit the views in any way and actually lent itself to having a lot of frontage overlooking Benjakiri Park and the Tobacco Monopoly’s lakes. We retained that existing central core...then what we did is put the facilities on the top floors, because there were no provisions on the ground floor, which was actually quite a bonus for buyers giving them rooftop views over Bangkok.”
