The 8mm chair and 6mm table were created to blend into the surroundings of the museum's new entrance and underground gallery, which opened earlier this year.
The furniture is minimal in appearance, made from sheets of bent aluminium in two different thicknesses – which also give the chairs and tables their names.
The material, which is typically used for aeronautical projects, is super lightweight, also creating a more comfortable, springy back for the furniture.
The pieces feature a slanting pattern made using laser-cutting that references the extension's porcelain floor, and created to cast striking shadows. The furniture is powder-coated in silver and white to match the colour of the tiles, and also a contrasting bright red.
AL_A worked with Moroso to ensure the furniture would be an "integral part" of the building, which adds an extra 6,400 square metres of space to the London museum, and is the largest expansion it's undergone in 100 years.
A recent series of photos, taken by Simone Bossi, used restricted viewpoints to highlight the extension's architectural details such as staircases and skylights.
AL_A, which was founded by Stirling Prize-winning architect Amanda Levete in 2009, also completed an aluminium-plated tower block in Bangkok earlier this year, and the undulating tile-covered MAAT museum in Lisbon in 2016.
It's not the first time Levete's firm has designed furniture for the London museum. It collaborated with design brand Established & Sons in 2012, alongside several other studios, to create a series of benches for the V&A courtyard.
Levete took 77th place in the architects' section of Dezeen Hot List, a data-based power ranking of the most influential people in design and architecture.
