^^ totally agree. As some have said, that range of height either in Back Bay or the West End is realistic, and spectacular.
If we're talking about Back Bay (and i'm speculating with the noose tightening fast) – with several garages in play around the City... with new offices and residences being added in the neighborhood, i see the Dalton St Garage's loss as too austere for Back Bay to be deemed a realisitic possibility just now. And it's really not even close. Then, it's importance just increases with time. With future capacity, ostensibly being taken up by so many big projects in Back Bay and downtown, then factor the tall tower rising above squeezing a smaller garage even more.
Didn't the BRA also quickly rebuff a proposed demo of Dalton St Garage a short time ago? Put me in the group with the others who said, 'no way.'
Lord & Taylor was given by generous donors on the forum as our best hope.... i recall reading some time ago, that the far south end of the Christian Science Ctr at Mass Ave and Huntington Ave is in play, but i'm keeping (the part of the Garage that's visible above ground) as my dark horse for a future tower.
Lastly, the West End. White hot nimby zone now, but maybe in 10 or 15 years, things would have quieted enough to pull down one of those Soviet Era turds.
That leaves the Monoliths. Nothing much over 700' is likely when they eventually come down, but it's amazing we're even at such a place where talk of future skyscrapers can be discussed openly in rabid anti-development circles like the Globe – in the context of where we were just a year or two ago with the fight over Copley Tower.
