Cross-laminated timber (CLT) is a type of mass-timber, engineered wood that can be used as structural building materials. It is often used in architecture and normally made from larch, spruce or pine.
In interiors, the material, which is sometimes known as super plywood, lends rooms a light, modern feel and can create a luxurious effect even for projects with a tight budget.
CLT is often used for interiors in Scandinavian projects but can be found in buildings all over the world.
This is the latest roundup in our Dezeen Lookbooks series that provides visual inspiration for designers and design enthusiasts. Previous lookbooks include cosy cabin bedrooms, Shaker-style interiors and rooms that look as if they are part of a Wes Anderson film.
London studio Tikari Works used CLT for the structure of the four-storey Rye Apartments block in south London.
The material was left exposed across the majority of the apartments’ gabled walls and ceilings and combined with spruce wood kitchen cabinetry, storage units and shelving. The timber finishes were complimented by terrazzo-style flooring with amber and cream-coloured flecks.
Pool Leber Architekten added a two-storey CLT extension to a 1980s housing block in Munich to create a series of loft spaces.
The structural timber is visible on the walls, ceilings and floors. It is paired with sculptural storage cabinets that double as window seating.
Structural CLT, which forms the floor walls and angled roof, is visible throughout the cabin.
“The ability of the CLT to serve as structure and finish removed the need for plaster-boarded walls, suspended ceilings, cornices, skirtings, tiling and paint; reducing by 15 per cent the embodied carbon of the building, its construction cost and time on site,” explained the architecture studio.
The panels were exposed throughout the interiors, where they were treated with soap and lye to lighten and protect the timber.
This CLT extension was added to a traditional Catalan house in the city of Reus. Catalan architecture office Aixopluc used lightweight materials for the building, which was prepared off-site and erected in just two weeks.
The thermal mass of the exposed cross-laminated timber interiors helps to ensure a comfortable internal temperature when the afternoon sun hits the building.
Ortraum Architects exposed the CLT structure throughout the internal spaces, which was pared with a simple concrete floor on the lower level and chunky furniture made from CLT.
Motiv Architects chose CLT for a garage designed to house a restored vintage Mustang and serve as a workshop for the owners’ industrial bag and belt fabrication company.
The design was “born out of a strong desire to work with cross-laminated timber – to better understand its properties as well as the efficiencies of its assembly on a project of a very small scale,” Motiv Architects said.
Designed to be transported on the back of a lorry so it can be taken to remote locations, this small artist’s studio was designed by Bobby Niven and architect Iain MacLeod.
Its gabled cross-laminated timber structure is exposed throughout the interior where a CLT mezzanine floor has also been inserted.
This Amsterdam townhouse designed by architecture studio MAATworks is arranged around an angular staircase made from cross-laminated pine.
Responding to the client’s desire to reference wooden Scandinavian homes, the wall and ceilings of the home are also made from exposed pine wood.
