A Financial District parcel overlooking the Rose Kennedy Greenway is on the market as downtown Boston’s latest luxury condominium development opportunity.

Colliers International Boston is marketing the 5-story office building at 149-151 Pearl St. along with a six-unit apartment building at 24 Charter St. in the North End.

The 1,807-square-foot Pearl Street parcel, which overlooks the Greenway’s Fort Point Channel Park, contains a 5-story, 7,500-square-foot office building with ground-floor that is 100 percent leased. Zoning allows structures totaling 18,000 square feet on the property by right.

The North End property is being marketed as a potential condo conversion. The properties, which have been under family ownership for decades, are being marketed as a portfolio as well as separately.

Removal of the elevated Central Artery has opened up redevelopment opportunities on properties facing the Greenway, but residential developers have only begun testing the market in recent years.

New Boston Ventures broke ground in 2016 on The Boulevard, a 12-story tower containing 36 condos at 110 Broad St. The building which is scheduled for completion this summer listed units starting at nearly $2.6 million.

And Brooklyn, New York-based Fortis Property Group has proposed 195 residential units in a 10-story addition atop the Dock Square Garage on Clinton Street.
