Re: 115 Winthrop Square | Financial District
With an observation deck, many of the people who'd entertain buying here would probably reconsider on privacy and security grounds.
To simplify this as much as possible: No buyers, no building.
Then sucks for them because there will be plenty of people lined up right behind them to buy a condo in the tallest brand new residential tower in downtown. I don't think people would care... like at all. This is a mixed use tower already so there are going to be thousands of people going to and from their offices every day, along with passing through the great hall, so they wouldn't even notice. Its not a secluded residential, the lower half is an office tower. The great hall literally invites the public to come hang out at the base level of this tower and use it as a pass through between streets, theres going to be a lot of activity. An observation deck would not affect their experience at all, especially if its built on top of the roof and above the top mech floor separating this from the top res floor. No floors lost whatsoever, and no space lost to the elevator either.
That being said me personally I would go 1 further and put a restaurant at the very top floor so the public has a restaurant with a view of the harbor and Custom House tower while they're eating, we deserve this. Then an escalator going up to the roof deck observation area from here just like the old WTC did. That means this tower would really become a part of the fabric of Boston and not an art exhibit behind a rope like the Hancock is that you just get to look at but don't touch. I would make this have the restaurant with the best views in the city, the roof deck for tourists to get to take in the amazing views of Boston, which would be stop #1 for most tourists just like the ESB or top of the rock is for tourists in NYC, and It'll have the great hall so people get to pass through the tower to the other street as a shortcut, and they can also stop and shop as well. The restaurant wouldn't affect people below either since they have a private restaurant mid way up MT and it doesn't affect anyone either. Give back to the public with the restaurant, obs deck, and great hall. Theres plenty of people who want to buy in towers like this if someone doesn't like these things then move aside because the next man will. Although your really not going to notice with half of the tower being an office tower and the great hall is public as well. Why not give back to the public? I don't get why people would not want this...
Ill explain the elevator again:
You already need a service elevator to get up to the mechanical structures on the top floor/roof. So its already being built regardless. Make it look like a regular elevator but really big like service elevators are, then you can fit a lot of people in it as well, use this service elevator to get the people to the roof of the building and then if there are a couple workers on the elevator with you, they can go off in their own direction that they need to go to get to the mech. If for some reason they don't want any workers with the guests...ever, then just have them go up after hours, along with bringing up heavy objects after hours.
Then if the restaurant plan was implemented, use the same idea but either have this big "service size" elevator stop at the restaurant level and then have tourists take an escalator up to the roof like the old wtc. or still have it stop at the roof and people wanting to go to the restaurant can take an escalator down to the restaurant or stairs. I think stopping at the restaurant would be better, copy the wtc style it worked great, but if theres no restaurant just use the other method where a service elevator stops on the roof and tourists use it during the day, maint uses it after hours. Whats the prob here? It gives back to the community and also makes money for the tower. I would love to eat at a restaurant with the custom house tower out the window and the harbor in the distance with the roof tops of downtown in front of me would you not? I also would love to go up to the roof to the only open air outdoor observation deck of this height in the city and be able to feel the air/breeze while looking out at the ocean, planes taking off and landing, the bunker hill monument, Zakim bridge, Hancock and Pru looking in the distance... This would be amazing.
