Going up: Development in and around Boston

The West End could get a new 40-story tower near North Station.

Why it matters: The development would loom over the North Washington Street Bridge that connects Boston to Charlestown and bring even more density to the Bulfinch Triangle area.

Driving the news: Newton-based developer RMR Group plans a 300-room hotel, 420 residential units and retail space at the corner of Causeway and North Washington Streets.

Over at the other main transit hub, the shuttered WeWork location across the street from South Station is being taken over by another co-working operation, New York-based Industrious.

• It'll be a prime location across from the new hotel/residences/commuter hub at the new Atlantic Avenue South Station tower.
• WeWork shut down the site in April.
• Industrious has other locations downtown, in Cambridge and Dedham.

ICYMI: The iconic Fortress self-storage building along I-93 in Dorchester could get new neighbors.

• A developer wants to put a six-story, 59-unit building in the Boston Street storage place's parking lot.
