English Bond is a bricklaying pattern where headers and stretchers are arranged in alternating courses, with queen closer bricks binding the walls. It can be adapted for thick walls by adding more brick courses. English Bond is slower to lay than variants like Garden Wall Bond that use fewer headers. Flemish Bond also features alternating headers and stretchers but within each course rather than between courses.
Introduction to Bonding - The basics
- 1. This is English Bond. Notice the headers in one course, stretchers in the next. The queen closer keeps the bond. Solid walls - English Bond Click (or wait) for next slide Wall 1 brick thick
- 2. On the right there are two examples of English bond. The lower one shows very dense engineering bricks - often found in factories and bridges etc. English Bond examples Make sure you understand the need for the queen closers (left). Click (or wait) for next slide
- 3. English Bond is slow to lay. Work is quicker if the number of headers is reduced. This is why Garden wall bonds are so popular. On the right you should be able to see that there are three courses of stretchers to every one of headers…. English Bond - Garden Wall Bond The number of bricks is virtually the same -it’s just quicker to lay stretchers and fewer bricks are rejected if they are too long or too short.

- 4. In most two storey houses the walls are 1B thick (approx. 225mm) High buildings need thicker walls. English Bond can easily be adapted. The right- hand picture shows two courses of a wall which is two-brickstwo-bricks thick. English Bond - Thick walls Click for next slide
- 5. This is Flemish Bond. Notice the headers and stretchers alternate in each course. Again, the queen closers keeps the bond. Solid walls - Flemish Bond Click (or wait) for next slide
- 6. Flemish Bond - examples Here are three examples of Flemish bond. Good quality housing from the Georgian and Victorian periods is usually in Flemish bond. Click (or wait) for next slide
- 7. Flemish Garden Wall bond Flemish Garden Wall bond is quite rare but it does exist. The example on the right shows two stretchers in each course followed by a single header. There are other variations. End of sequence
