Offers due 2/13 at noon. Exceptional development opportunity on a highly visible corner lot in the heart of Cambridge. Directly adjacent to the Cambridge Public Library, this premier site offers unmatched light, exposure, location, and prominence, making it an ideal setting for a landmark residential project. Take full advantage of Cambridge’s new high-density zoning ordinance, allowing up to 6 stories with affordable housing or 4 stories by right, with no set limit on unit count or FAR (buyers & agents to perform due diligence). This zoning flexibility creates a rare opportunity to develop either high-density luxury condominiums, rental units, or spacious, large-format luxury residences in one of the most supply-constrained markets in the country. Corner parcels with this positioning, visibility, and zoning potential almost never come to market, particularly in such a central and established location.
