Design a house with equilateral triangle rooms

This is a very out of the box concept for a home/room design. I am looking for some interior design ideas of what it would look like for a home design with rooms that are not square, but triangular. Each wall will be 5 meters wide and 2.5 meters high in an equilateral triangle shape. The setup will be two of these rooms on top of each other so a total height of 5 meters. The "roof" will be flat with solar panels and windows for light. The walls will be solid steel with no windows so there needs to be some factoring in for light getting to the lower level as well as a means for getting from the top level to the bottom level (could be a ladder, different styles of stairs, etc). I would like one design of just a living room with a bedroom on the lower level and another design of two of these attached to each other (with an opening between the two) with a living room and kitchen on the top level and bedroom and bathroom on the lower level. All with furniture, fixtures, lighting, etc. I would like several different options as I am using this to demonstrate the viability of such an architecture. My preferred deliverable would be in Blender but if it is just a conceptual picture drawing that would be fine too. I have attached a basic picture of the shape of the building. The key is to show that someone could actually live in such a structure, even better if it can look like something that would be more fun to live in than a square room.
