The ground floor of the existing One Broadway highrise has now been completely gutted (the portion under the highrise).
Here's a design review submission from earlier this year that covers this:
https://www.cambridgema.gov/~/media...02_303_mit/sp302_design_submission1.pdf?la=en
That doc includes this description of the changes to the existing One Broadway structure:
One Broadway additions and alterations include the following:
• The addition of a one story retail “Liner Building” fronting Broad Canal Way
• The relocation of the office lobby for One Broadway eastward to make way for an expanded
retail space at the corner of Broadway and Third Street, in an effort to further activate that
corner of the building site
• The expansion of the existing retail fronting Broadway to include a proposed grocery store and associated food prep and storage space in the existing basement
• The addition of two small levels of office above the grocery store in front of the existing
parking garage façade
• The addition of a roof terrace above the new office
So, apparently some portions (but not all) of the 2008 renovation are being undone/redone - that was short lived!
