Two Bridges, Manhattan to undergo further development
Situated within Manhattan, Two Bridges is continuing to undergo extensive development, at which a fourth skyscraper is proposed for construction.
Set to complete in 2021, this new mixed-use skyscraper will incorporate over 700 apartments over 62 storeys, of which 183 housing units (approximately 25 percent), will be placed within affordable brackets to counteract the increased demand for housing in the area.
Located at Clinton Street, Starrett Corporation is behind the proposed new development and aim to deliver a number of benefits within the build by incorporating a number of retail and communal facilities.
Construction work would begin in 2018 and contain shopping outlets, fitness facilities and office space, in addition to providing essential landscaping in order for the development to blend seamlessly within the space.
The construction alongside three other developments will not only provide long-term benefits, but attract further tourism to the area and make the area a more appealing and affordable place to live.
However, although Josh Siegel, President of Starrett Corporation has said, “We recognize it’s a prominent building, but we are building in accordance with the existing zoning", residents have already expressed their increased concerns regarding the construction of the new building.

University of Dresden constructs carbon concrete building
The Technical University of Dresden, in partnership with German architecture firm Henn, is constructing the first building to be made out of concrete and carbon fibre, rather than traditional steel.
The combination of materials, known as, “carbon concrete” has the same structural strength as its steel-reinforced alternative but less concrete is used, according to researchers at the university.
The building, called “The Cube” is currently under construction at the University of Dresden’s campus in Germany, and is believed to be the first carbon concrete building in the world. Strengthening the concrete, the carbon fibre yarns are used to create a mesh into which the concrete is then poured.
Unlike steel, the mesh is rust-proof meaning that the lifespan of carbon concrete is longer than that of the more typical steel-reinforced concrete. This also allows the layers to be much thinner than steel.
The design and shape of The Cube
According to the companies, the flexibility of carbon fibre allows the walls to fold up and become a roof. In a statement talking about the building’s design elements, Hen said: “The design of The Cube reinterprets the fluid, textile nature of carbon fibres by seamlessly merging the ceiling and walls in a single form, suggesting a future architecture in which environmentally conscious design is paired with formal freedom and a radical rethinking of essential architectural elements.
"The wall and ceiling are no longer separate components but functionally merge into one another as an organic continuum.” Displayed as a showpiece for TU Dresden’s major project, backed by the German Federal Ministry of Education and Research, The Cube aims to explore the potential uses of carbon concrete in construction.
"Carbon concrete could contribute to more flexible and resource-saving construction processes, and switching to carbon concrete could reduce the CO2 emissions from construction by up to 50%," Henn said in a statement.
Bio-based carbon fibre under development to reduce carbon footprint
While carbon fibre may be lighter and stronger than steel, it has a much higher carbon footprint. Describing the material’s impact on the environment, Dr Erik Frank, Senior Carbon Scientist at the German Institute of Textile and Fibre Research Denkendorf (DITF), said it is “usually very bad.” To reduce the carbon footprint, Frank is finding ways to make carbon fibre out of lignin, a common plant-based substance found in the paper manufacturing industry.
