We were never going to get a new, tall, tower because the space between the existing buildings isn't wide enough. We were never going to demo the existing office tower because the replacement cost would outweigh the profit. Reclad and refurb was *always* going to be the name of the game here. I'm sorry but if folks thought we were going to get Langham Place or Ginza-Six-meets-Shibuya-Sky you were only deluding yourselves.
Cost to replace was always going to be sky high but was the 4th option ever considered: building a connected building, essentially widening the existing office tower, and then going taller? Or would cost be prohibitive again due to the subway below and cost to re-enforce the existing office building?
