Named The Cube, the 10-storey residential building was constructed using a hybrid structure that is primarily cross-laminated timber (CLT), but also integrates steel elements and a reinforced-concrete core.
London studio Hawkins/Brown believes it is the tallest example of its kind on the continent, and demonstrates the opportunities for using hybrid construction to make high-rise buildings more sustainable.
"The Cube breaks new ground and demonstrates the great potential of cross-laminated timber as a material that enables rapid construction with a reduced environmental impact," explained practice associate Alex Smith.
CLT is an engineered wood formed by glueing together several layers of lumber at right angles to each other, making it much stronger and more rigid than normal wood. Other examples of its use in architecture include OOPEAA's Finlandia Prize-winning Puukuokka apartment block in Finland.
By combining this material with steel members, the architects were able to create a more complicated structure featuring numerous cantilevered overhangs.
The system was developed by timber and steel specialist B+K Structures. Both the CLT panels and the steel frame were manufactured offsite, then combined during construction.
The Cube is located beside the Wenlock Canal basin. With a total floor area of 6,750 square metres, it accommodates 50 apartments – between four and six per floor.
To offer residents views up and down the canal basin, or across the park to the east, Hawkins\Brown developed a twisted cruciform plan that gives all of the apartments three external walls.
"The cruciform layout of the development is an important factor in the quality of the apartments – homes with three external walls have great access to natural light and can be properly cross-ventilated, making them more comfortable during hot weather," said Smith.
"It also creates wonderful views, which we have maximised by ensuring each apartment has a decent-sized balcony or terrace."
This arrangement also forms courtyards at the four corners of the plot – something the design team describe as turning the traditional inward-looking courtyard block on its head.
Externally the block is clad in two materials; a black brick screen wall creates a visual affinity with the neighbouring buildings of the surrounding conservation area, while other sections are covered in slatted western-red cedar.
The project was completed for London property developer Regal Homes, and also includes approximately 1,200 square metres of commercial space on the ground floor.
"The Cube was created to be a pioneer of architectural possibilities, pushing the boundaries of residential construction and developing homes that are also works of art," said CEO Simon de Friend.
"Arguably the 'unbuildable building', our in-house construction arm has broken new ground with this project and we will look to building on this legacy with further CLT developments in the imminent future."
