This is the exterior facade view. In order to give a proportional conception, I put human and tree 3D models to give a comparison.
These two images show the ground floor which is used as the art gallery. The spiral stair goes up to Mueck's studio. On the contrary, another cantilevered stair goes down to Banksy's studio. And their art works are hung on the wall.
Here's the studio of Mueck. It's like an attic which is hemi-sphere shape. Considering his art works are mainly large sized, I arranged a spacious room for him. And it makes the sense of the word "surface", to some extent, by the sphere exterior and interior appearance. The right image is x-ray which makes clearly.
Then it is the studio of Banksy. Obviously it's a basement (since it ia below space). The ceiling of the basement is transparent which makes things be able to see from both sides of upper and lower storey. It makes a sense that Banksy did works in a common or even unconspicuous place but was able to observe the society clearly, which helped him on his social issues art works. On the contrary, he is exposure to others, giving a sense of the word "impulsion". Also, the right one is x-ray.
Secondly, short videos...
This is a section view, front to back and above to below.
The above space - Mueck's studio. Through the spiral stair, it is also a good tour scanning the art works in the gallery.
The below space - Banksy's studio. Walking downstairs and having a view of the basement.
