To build a house and build a wall, what bricks can you use besides red bricks?

You can also use blue bricks, cement bricks, stones, etc.

Besides red bricks, there are also blue bricks. If conditions permit, you can also selectively build a wall with stones bought from quarries at the root of the wall, and use red bricks or blue bricks at the upper part.

If there are local cement bricks for sale, and the price is low, then cement bricks can be used instead of kiln bricks.
