Tiling transition advice. - Tile Advice

[oomxena]

I have a room 3m X 8m , which has a change of direction at about halfway down the room 8m side. I want to keep the lines parallel to the walls , how do tile the transition with out using little pieces of tiles , should it have the joint where it changes direction, then cut from smaller to bigger to get 90 degrees lines on both sides of the bend .the layout is brickwork The bend if going from the center of small side to opposite side is about 900mm , any help with this transition.
