Huge drop predicted for Greenwich office rents Average Greenwich office space is $70 ft compared to $46 in Stamford and $36 in Fairfield County as a whole. Antares says that its UST building is fully leased to hedge funds at over $100 sq. ft. and, while a lease is a lease, one can wonder how long those tenants will last. One fund, Duff (Asociates?) is seeking to sub-let its contracted for 15,000 ft of space but that would be Duff’s problem, not Antares. But as prices drop and the disparity between neighboring areas grow, I’d think that some clever people will be looking to their landlord for concessions and/or least terminations. And of course, there’s always the issue of whether all those hedge fund tenants will survive to move into the new building.
