PORTLAND, Maine (WGME) — Dozens of tiny apartments could be coming to Portland, packed into a new seven-story building.

The city’s planning board this week approved the construction of the building off Congress Street, which will contain 87 units, each between 225 and 280 square feet.

Patrick Boothe, principal architect at Woodhull, presented the project by the real estate group GreenMars to the Planning Board Tuesday.

“It is at a very prominent corner of Washington and Congress Street, so it is our objective to transform this key intersection from an underutilized parking lot into a vibrant anchor for the neighborhood,” Boothe said.

Boothe said the units will be market rate, “designed for efficiency to keep them more accessible than typical new construction on the peninsula.”

The actual prices remain to be seen, but slightly larger studio apartments on the peninsula were listed on Zillow for $1,600 to more than $2,000 a month.

The project still needs final approval.
