More than 3,500 m3 of timber has started to arrive on site in Dalston Lane, Hackney, as work gets underway on a record-breaking cross-laminated timber (CLT) residential structure, which will become the tallest of its kind in the world. The 121-unit development is estimated to use more timber than any other project in the world, making it, by volume, the largest CLT project globally.
The project will provide significant residential capacity with 121 units over 12,500 sq m, and over 3,460 sq m of commercial space.
For the architects Waugh Thistleton, CLT engineers Ramboll and developer Regal Homes, the most exciting aspect of the project is the sheer size of the structure and its completion without the use of thousands of cubic metres of concrete.
In total, Ramboll’s CLT experts have calculated that the building will save 2,400 tonnes of carbon, compared to an equivalent block with a concrete frame. By using CLT construction, the embodied carbon is 2.5 times less than that of an equivalent concrete frame. Taking into account that timber stores carbon by absorbing carbon dioxide (CO2) from the atmosphere, which is also known as ‘sequestered carbon’, the structure can definitively be considered as ‘carbon negative’.
