In masonry, there are at least five common brick bond types: English, Common, Running, Stack, and Flemish bond. A bond itself is a pattern that shows how blocks are arranged within a structure. In architectural craftsmanship, the Flemish motif is one of the most popular patterns. The Flemish bonds are mainly decorative and appear more attractive than others. This type of arrangement has a downside.
This article provides an overview of what makes Flemish bonds stand out and remain popular since the 17th century. It discusses the types and what distinguishes them from regular English brickwork. The comparison will cover what each technique really means, its strength, and its structural complexity. This is crucial for you who are currently in the architecture, engineering, or construction professional world.
What is Flemish bond?
The Flemish bond is a brick pattern that alternates the long side of the stone (a stretcher) with the short square side (a header) in the same course. The headers (shorter ones) are glazed or fired differently, so they become darker and shinier. This makes the overall building more lively and unique.
The name suggests it comes from Belgium, France, or the Netherlands. However, the Flemish brick structure started in Northern and Central Europe, especially in Poland, Germany, and Georgia. It became popular in European buildings during the 17th century. An early, rough but striking example is Munich’s famous Frauenkirche, built between 1468 and 1488.
The pattern later spread to British colonies in North America, mainly Virginia and Pennsylvania. Today, you can still find many famous buildings using a Flemish bond, such as Kew Palace in London, Gloria Dei Church, and St. Luke’s Church in Pennsylvania and Virginia. In recent years, this brick design has been used in different variations for modern construction.
Types of Flemish bond
There are two types of Flemish bond in general: double and single. Both types differ in how the blocks are put together. Each has its own physical qualities and features. These differences affect how the workers build the wall and how the finished barrier looks. Architects and clients must consider the construction method and costs when choosing which type to use.
Professionals usually check if the Flemish pattern is the same on both sides of the wall. If the motif appears only on one side, it’s called a single Flemish bond. These types of designs matter because different building styles benefit from using the right concrete block type. Builders often choose the double-sided model when both sides of the barrier will be seen by many people. To better understand, here are explanations of each type:
Double Flemish bond
In a double Flemish bond, the brick pattern shows on both sides of the fence. This creates a thick, strong structure with a very attractive look. Headers and stretchers alternate in every course, continuing throughout the entire wall. Builders choose the double-sided type when they want both sides to look aesthetic. It usually costs more than the single type.
Single Flemish bond
With a single Flemish bond, only one side of the wall displays the pattern, while the other side uses a simpler English masonry as backing, with stones filling the courses. These fences are about one and a half bricks thick. The arrangement only shows one side of the barriers. The single type is a more affordable and easier option that still provides an attractive appearance on the visible side.
The difference between English bond and Flemish bond
As mentioned above, Flemish bond patterns enable each course to alternate between headers and stretchers. This makes the wall look like it has a certain motif. The English brickwork alternates full header in one row and full stretcher in another. It somehow makes the design less aesthetic because the courses will just look plain from afar. Both types of bonds have their own advantages and disadvantages.
The Flemish bond provides one full brick thickness. English walls are usually even thicker, often more than 1.5 masonry units thick. Flemish decorative designs are generally a more economical option to consider. It requires better-skilled workers to put together the blocks consistently. English bonds are more expensive but require only intermediate-level skilled workers.
Flemish patterns are highly resilient to strain. The wall does not require routine cleaning. English bonds demand more regular cleaning due to their mortar joints. Both have strength, stability, and are not likely to collapse. The Flemish architecture is prettier, but also more technical. English brick layouts are simpler but need proper maintenance.
Where is the Flemish bond used?
The builders often use a Flemish bond in garden fences, partitions, and buildings that require thick, sturdy brickwork. Constructors like it for its elegant look. This type of bond is a great choice for facades and exterior walls. It is relevant especially when they want a detailed, handmade style. You’ll find it in restoration projects and high-end residences, where traditional design is important. Some common places where this artistic structure appears include:
- Front facades of houses and public buildings: It creates a neat, elegant look and is common in Georgian, Victorian, and Colonial-style architecture.
- Historic buildings: Many churches, town halls, and old universities use this brick construction, especially in Britain, Belgium, and the Netherlands, in the 1700s and 1800s.
- Exposed walls: Boundary fence or garden partitions have to be visually appealing since both sides of the barrier are visible. In these cases, architects often use a double Flemish bond to display the same pattern on both sides.
The process of building the Flemish bond
To build a Flemish bond, a worker puts each row of bricks by alternating the shorter and longer parts. If the first row starts with a header, the next row starts with a stretcher, and this pattern continues. They must place the headers in each row exactly above the centre of the stretchers underneath. It prevents the formation of vertical joints, so that the walls can be stronger and more stable.
The construction needs good planning and high-quality materials from start to finish. Using a single or double Flemish bond, it’s important to use the right amount of mortar and keep all stones straight and level to make sure the wall looks good and stays strong. A consistent course will result in a classical Flemish pattern at the end.

Flemish bond is popular due to its decorative pattern. Building exposed fences and wanting to highlight their beauty means considering this type of wall layout in your design. Skilled craftsmanship is crucial in this artistic work. This is especially important when cutting bricks and maintaining consistent joint thickness to achieve a neat, symmetrical finish.
