It appears that most architectural visualization projects made with Blender and rendered in Cycles have interior scenes as the main subject! Here is another project from an artist called wassim24 and posted at the Blenderartists forums. It is an internal view, and the project name is “The cabinet“. At the bottom of the page, the artist also shares some information about the production.
An interesting point about this project is that, according to the author, all the process have used Lion Render. The total time for the scene is about fifty minutes, and since he manages to get it on a render farm, it probably didn't struggle to get all of his computer resources to cook this image.
In case you are not aware, all students from Blender 3D Architects courses have an exclusive access to Lion Render, and can enjoy some rendering power on their system at no extra cost. Just enroll on any of our courses, and you can get started. To know more about the partnership, you can read the conditions here.
