This week, Dezeen shared some of the proposals revealed by designers for Notre-Dame Cathedral's new spire, after it was engulfed by a major fire last week.

The flurry of designs were unveiled following the French prime minister's announcement that there would be an international competition to replace the structure.

Among the proposals were Studio Fuksas' Baccarat crystal roof, Vizumatelier's light-projecting tower and Mathieu Lehanneur's visual of a "permanent flame".

Meanwhile, Concr3de suggested that parts of the gothic cathedral should be rebuilt using 3D printing using material from the fire.

To demonstrate the concept, the Dutch company reproduced Le Stryge, a gargoyle that was severely damaged in a fire, from a mixture of limestone and ash.

In the design world, IKEA unveiled its first redesign in 36 years. Intended to increase readability, it sees the blue block letters of the iconic logo enlarged inside the yellow oval.
