Minecraft Modern house where I do not need so much material?

Would like to build a modern house in survival where I do not need much different material

Tiny house - maybe that's something for you

Quartz is always good for a modern house, but if you do not want to go into the nether you can also take clay.

Is it hard to find quartz in the Nether?

It comes naturally to the place where the Nether Portal spawns, but actually it is relatively easy if you have the right equipment for the Nether, as it can be relatively quickly dangerous in the Nether.
