This week on Dezeen, we reported on the top installations shown at London Design Festival, including furniture made from a car and innovative biomaterial designs.

The annual design festival, which takes place across 13 design districts in London, featured a number of exciting installations including Andu Masebo's Part Exchange project, which saw the designer transform a scrapped car into eight furniture pieces (above).

The festival also showcased a number of products made from biomaterials, including a version of fashion brand Ganni's Bou bag made from bacterial leather by London biotech company Modern Synthesis.

Natsai Audrey Chieza and Christina Agapakis used the event to launch what the designers are calling the "first biodesign lifestyle brand", while at hotel One Hundred Shoreditch the Time Is Running Out exhibition displayed 24 clocks made from biomaterials.

Among the other projects on show was architect Daisuke Motogi's reimagination of Finnish designer Alvar Aalto's Stool 60, which Motogi created in 100 alternative versions.

In Hackney, IKEA and H&M's design incubator unveiled products by 22 emerging London studios.

Also this week, Dezeen editor Tom Ravenscroft revealed everything you need to know about Saudi Arabia's 14 "giga projects", including Neom, which will consist of 10 regions.

Among them is the ski resort Trojena, which has a "holistic harmony", according to its project director.

However, in an opinion piece, architecture and urban-design professor Dana Cuff argued that a recent documentary about another part of Neom, megacity The Line, paints a bleak picture of the architecture profession.

In design news, Swiss watch brand Rado unveiled a two-toned timepiece informed by architect Le Corbusier's colour palette called True Square Thinline Les Couleurs Le Corbusier.

Elsewhere, Canadian designer Thom Fougere created a small collection of ring-shaped benches cut from a single plate of steel, which were installed in the woods outside of Winnipeg.

Popular projects on Dezeen this week included a relocatable home by architect William Samuels, a trio of pastel-coloured townhouses in Norway and a black house in San Francisco by Mork-Ulnes.

Our latest lookbooks featured living rooms with cowhide rugs and interiors with monochrome colour palettes.
