Today I started my European trip a bit early by visiting a new development in the London Borough of Hackney. The Dalston Lane site is a development of social housing using CLT as the principle construction material on a concrete base. Only early on in the construction it only has couple of layers of CLT in place on one part of the site, however once completed it will be an impressive timber building.
The developers state that when completed, Dalston Lane will be the tallest residential CLT building in the world. Nine storeys of CLT structure sit on a first floor concrete podium slab, reportedly reaching a height 0.5m higher than Forte Melbourne (32.17m). However, how long this record stands is another question. The construction combines a diverse team; B&K Structures (specialist timber constructions), Ramboll (structural design), Waugh Thistleton Architects, XCO2, PJCE and Regal Homes.
Dalston Lane is a 121 unit residential development in Hackney, UK. Estimates show that it will use more timber than any other scheme in the world, making it, by volume, the largest Cross Laminated Timber (CLT) project globally.
The use of CLT boasts many benefits, not least its sustainability. In total Dalston Lane will save 2,400 tonnes of carbon, compared to an equivalent development using a concrete structure. 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 sequestering carbon dioxide (CO2) from the atmosphere, the structure can be regarded as ‘carbon negative’. Its 3,852 cubic metres of CLT will make up the external, party and core walls, floors and stairs.
Dalston Lane will join a number of other timber buildings in the area thanks to The London borough of Hackney’s ‘timber first’ policy established in 2012, making this central London borough a world leader for timber construction.
A big thanks to Nick at B&K structures for organising the visit.
