Northwind Group is providing a $231 million construction loan for the office-to-residential conversion of 675 Third Avenue, a roughly 337,000-square-foot office tower in Midtown Manhattan, according to a release distributed Monday by PR Newswire.
The borrower is converting the building from office to residential use; the release did not name the ownership group's full capital stack beyond Northwind's loan or state a unit count for the finished building. Northwind previously financed the conversion of the Pfizer headquarters building nearby, and Crain's New York reported Tuesday that the same development team has now landed the $231 million loan for this second, nearby project — meaning one conversion sponsor is now running two Midtown office-to-residential jobs back to back with the same lender.
Office-to-residential conversions carry their own trade mix: gut interiors, new vertical risers for plumbing and ventilation, window replacement or modification for light and air code, and life-safety systems rebuilt largely from scratch, all inside an occupied-footprint structure that doesn't get touched on the exterior. A $231 million loan on a 337,000-square-foot building works out to roughly $685 per square foot in financing alone — a number that signals a full gut rather than a light renovation.
David Werner's reported purchase of a 49% stake in Fisher Brothers' 605 Third Avenue tower, reported by Yahoo Finance in late October, and the Pfizer-adjacent project both sit in the same few blocks of Midtown's east side, suggesting a cluster of conversion and recapitalization activity in that corridor independent of this specific loan.
**What to do next:** Interior demolition, MEP, and riser subcontractors should treat this as a live bid opportunity forming now — construction financing of this size typically means a GC is already selecting trade subs or will be within weeks. Firms with institutional conversion experience (plumbing stack replacement, new egress stairs, curtain-wall modification) should reach out to Northwind Group or track permit filings at 675 Third Avenue through the city's DOB portal for the GC of record once it's filed.
