Building a brick wall, Flemish Bond


Home extention brickwork

When you lay bricks for the first time it's a good idea to practise first with a soft mixture of sand and water which can act as mortar, or alternatively you can build a wall dry. Also don't forget you'll need a foundation strip for your wall before you actually start to build it.



  1. Fasten string lines on pegs and stretch the string line across the foundation strip.
  2. Dry-lay the brick to give you an idea of how the brick wall will look.
  3. Start by laying the first corner brick from the left side. Lay the shorter end of the brick (header) facing you. 
  4. Next, lay two stretcher-bonded bricks (long side of the bricks) side by side, facing you.
  5. Lay another header brick. Don’t forget to leave a 1 cm (3/8 in) gap between each brick.
  6. Finish dry-laying the first course of bricks, alternating the header and stretcher.
  7. When you are sure of this first course, re-lay the bricks.
  8. This time, fill in the gaps between the bricks with 1 cm (3/8 in) mortar joints.
  9. Check if the course is level with a spirit level.
  10. For the second course of brickwork, lay the brickwork at the header end if your first course was a stretcher course, and vice versa.
  11. To complete the wall, alternate the headers and stretchers in every course.
