I'm trying to come up with a flooring layout for a corridor with Granite of different colours and specifically of a specific pattern, such as the one below.
Given a corridor dimension, I need to visualise how it would appear and what dimensions of these granites and what quantity I'd need. - And a few options of these different sizes.
I'm aware that building architects use Autocad and other such software for that purpose. I'm interested to know how I can use any accessible software mostly those used for web design, such as Sketch, Photoshop or any other online design software with layout definitions and patterns for the purpose above.
In the least, at least I want something to do the following to scale, which I was thinking up using a pen and paper.
What options do I have?
