This is one section of a made-up banquet hall room I illustrated myself. I used a few reference images for design and points-of-view.
The color scheme was done through research on what colors are often used in catering hall rooms. Having a natural eye for color-combos, I was inspired by having vibrant tones (like the purple) go with muted or achromatic gray (neither warm nor cool–just purely black and white mixed together).
Many banquet room carpets have detailed designs or patterns. However, I decided to simplify my catering room’s floor design. I drew this in Photoshop, and although you can make patterns look neat and professional there, for this POV, it ended up looking the opposite. So I chose to use stripes instead.
I am also more fond of modern design than old-fashioned design. It was even easier to create simple bulbs with light rather than chandeliers. The walls also don’t have relief textures or fancy wallpaper.
About the dancefloor? It was added since many catering events have dancing. I elected not to do anything unusual to it so that it would appear believable. Of course, not all dancefloors are created equally. But I saw no reason to do something over-the-top to it.
Below is a continuation of this room.
This here is the opposite side of the picture at the top. I added tables to test layouts for this room. There are doors and an exit sign above it.
Of course, not being an architect, I have no plans to submit these to be designed. This was just to test my illustration skills and see what else I could do.
