Renderings of Seaport Office Tower Released Boston Global Investors plans to construct a 600,000-square-foot office building on a 1.1-acre parcel along Congress Street. The development rights went to a team led by John Hynes’ Boston Global Investors, which agreed to pay Massport $120 million for a 99-year lease for the site and access to a nearly half-acre parcel across the street known internally as “the triangle.” The street-level space will consist of a “grand hall” where eateries or nonprofits could set up. (The arch-like structure will minimize the need for columns in that ground-floor area.) The second and third floors will include two civic spaces, such as modest-sized performance venues. A new public connection would be made between the elevated World Trade Center Avenue and Congress Street below. And the developers would spruce up part of the viaduct — more like a park, less like a desolate bridge. Then there’s that “triangle” parcel, bounded by highway ramps. A single-floor building devoted to civic uses — billed as an innovation and cultural center — would go there, topped with a rooftop park and connected to the office building parcel via a pedestrian bridge. The 18-story main building would include 525,000 square feet of office space. BGI’s team, Massport says, expects to spend roughly $425 million on the entire project, including the public-realm improvements (and excluding the land costs). Construction could start in two years, and the building could open within four. Rendering Below: via Boston Globe

Neponset Wharf
- Aug 07, 2018

Mayor Walsh Calls for Review of Neponset Wharf Proposal Amidst Community Concerns Amidst an array of community concerns, from the height of the project to traffic issues, Mayor Walsh has released a statement asking the development team at City Point Capital to review their proposal for Neponset Wharf.  Residents of the Port Norfolk neighborbood have been vocal about their issues with the project since the proposal was submitted just over a year ago.  State Senator Nick Collins and State Rep. Dan Hunt have also come out on the side of the Dorchester community. The development team at City Point Capital has attempted to allay the community concerns by amending their design and scaling back the project.  Orginally set to include a 25 room boutique hotel and 150 condos the hotel has been scrapped and the condo count reduced to 96.  The plan still includes a boat house, parking for 170 cars, and around 3,000 sf of retail space.  The plan also outlines new waterfront outdoor spaces, with over 50% of the site reserved as public use.  

Two Wells Avenue
- Jan 10, 2018

New-construction Class A office space completed at Two Wells Avenue in Newton Newton’s Wells Avenue premier office district has received 135,000 square feet of new Class A office space with the completion of Two Wells Avenue, a new-construction office building featuring a floor-to-ceiling glass curtain wall facade and a modern amenity package. Two Wells Avenue was constructed off of the bones of a single-story, 69,000-square-foot office building constructed over 40 years ago. About 20,000 square feet of the original building were preserved. The original Two Wells Avenue was partially demolished and expanded to three stories in height, nearly doubling the property’s square footage. New utilities and underground storm water filtration were added, and the building was outfitted with exquisite finishes such as stone interior floors and wood exterior accents. A new grand lobby featuring a two-story waterfall and a cafe was constructed at the building’s entrance. Office space at Two Wells Avenue is now available for lease. The building is located minutes from the new Kendrick Street exit on Interstate 95/128, as well as the Needham Street retail corridor. Downtown Boston and Cambridge are located a short drive away as well. The following are photographs of Two Wells Avenue:
