If you want to avoid having construction lines on your drawing, construct your wall on a piece of sketch paper first. Then use it as a guide directly from the grid stage or draw the brick outlines and then trace it onto your final drawing. Before you start drawing, decide how many bricks high your wall is and how many high the bricks should be.
Draw the front vertical edge of your wall, measuring out the height you want, and then draw the vanishing lines back to the vanishing point. Mark out the height of the bricks on the wall, and draw those vanishing lines too. Remember, these are your 'working lines' so make them light and precise.
