There were just a couple of final refinements. The floor panel is just a cube. Drawing edge loops, I created the necessary faces to extrude inward as shown in the image (Fig.06).
The lamps are a plane with some edge loops that I moved to create the profile. Then I deleted the big central face in order to have just the thin frame and extruded it (Fig.07).
The frames of the windows were made in the exact same way, but I was careful to position the edge loops like in the image in order to create those nice rounded corners. I put some edge loops on the interior side of the frame and extruded the faces in order to create two nice cuts in the geometry in which to place the glasses (Fig.08).
The model was done! As you can see, the process of creating a concept model is pretty fast; in a few hours you can design and model everything you need. Architecture is often made up of standard elements, as in this case. Model one piece well and duplicate it as many times as you need, creating visually complex models.
It was time to render the model! I created a new camera and placed it properly in the corridor.
For the rendering I usually rely on V-Ray. It's one of the best software packages out there for easily achieving beautiful and fast renders (Fig.09).
The hangar is lit by a big rectangular light at the top of the structure. In the image you can find the parameters I used. But this was not enough to properly light the hallway. Here I tried to approximately recreate a real lighting scenario (Fig.10 - 11).
