This week on Dezeen, the "first NFT digital house in the world" sold for over $500,000 as global interest in virtual design continued.

Named Mars House, the colourful virtual home designed by Krista Kim was sold on NFT marketplace SuperRare for 288 Ether ($512,000), a cryptocurrency similar to Bitcoin.

However, following the sale, a dispute broke out between the artist and visualiser over the ownership of the artwork.

As interest in virtual design continued, American interior designer Kelly Wearstler revealed a virtual garage in the desert that she imagines housing basketball player LeBron James' electric Hummer.

Meanwhile, designer Marc Thorpe visualised a virtual house with vaulted concrete arches for a riverbank in Georgia.

Dezeen announced that we will be hosting a social evening in a virtual rooftop bar to discuss the rise of the metaverse with Space Popular, Andrés Reisinger, Amber Jae Slooten and Charlotte Taylor.

The virtual discussion will be the first Dezeen Club event.
