Building permit and planning records from Portland’s planning offices indicate that nearly 150,000 square feet of new office space is under construction in the city. That new space will add to 74,000 square feet of offices that opened in the past year, in a new building on Middle Street and in the new Patrons Oxford Insurance headquarters near the Portland-Westbrook city line.

Developers have proposed another 314,555 square feet of office space in various other projects in the planning stages, including a major expansion of the Idexx headquarters in Westbrook, but local real estate brokers have expressed doubt about whether all those projects will actually be built.

Not illustrated on this map are two significant office projects in Yarmouth that opened in 2017: a 94,500-square-foot expansion of the Tyler Technologies building near the Yarmouth-Cumberland town line, and a new 35,000-square-foot headquarters for Patriot Insurance Co. at 705 U.S. Route 1.
