Hello! This is Kakeru Koumuten Co., Ltd.!
Closed exterior refers to a style that has been used in Japan for a long time.
Many of you reading this article may be wondering whether to go for a closed exterior.
In this article, we will explain in detail what a closed exterior is, as well as its advantages and disadvantages.
目次
What exactly is a closed exterior?

A closed exterior is a style that surrounds the house with a fence and wall.
It is called a “closed exterior” because it can shut out the view from outside.
Closed exteriors are often used in:
・Houses facing busy roads
・Houses with large windows
and are a commonly used style.
What are the advantages of a closed exterior?
Next, let’s take a closer look at the advantages of a closed exterior.
No need to worry about being seen
By opting for a closed exterior, you can shut out the view from outside.
This means you no longer have to worry about being seen, allowing you to relax and enjoy your time.
・Want to hang laundry in the garden
・Want to have a barbecue in the garden without worrying about being seen
This style is ideal for those who have such thoughts.
Reduces the risk of children running out
Open exterior designs, which often do not include walls or fences, are quite popular; however, because there is no boundary between the house and the road, the risk of small children and pets running out is high.
By opting for a closed exterior design, you can reduce the risk of children running out.
Enhances security measures
By choosing a closed exterior design, you can strengthen your security measures.
This is because, in the case of an open exterior, the inside of the property is fully visible, which can give suspicious individuals the impression that it is “easy to enter.”
However, by opting for a closed exterior design, you can create a psychological effect that makes it feel “somehow difficult to enter.”
This contributes to enhanced security measures.
Some people go the extra mile with security measures by:
・Installing a locked gate
・Building higher walls
These individuals take security very seriously.
What are the disadvantages of a closed exterior design?
Next, let’s take a closer look at the disadvantages of a closed exterior design.
Can lead to a feeling of oppression
A closed exterior design surrounds the house with walls or fences.
This can make it easier to enhance security and privacy; however, it can also lead to a feeling of oppression.
If the house becomes too closed off, it may actually become more difficult to relax, so if the property is relatively small, it is better to incorporate fences or other elements with gaps.
Higher costs
A closed exterior design is significantly more expensive compared to an open exterior design.
In the case of an open exterior, you only need to install fences or walls in certain areas, but for a closed exterior, you need to install walls or fences around the entire perimeter, which inevitably increases material and labor costs.
Some people building their homes choose to carry out exterior work simultaneously with the construction of the house, but since the costs for the house and the exterior are separate, it is advisable to discuss the budget thoroughly.
It becomes difficult to spot intruders from the outside
While it is a very rare case, by opting for a closed exterior, it becomes harder to detect intruders from the outside.
This is because there are many places to hide.
Although the probability of an intruder entering your home is relatively low, it is not 0%.
If you choose a closed exterior,
・security cameras
・sensor lights
Let’s enhance security measures by utilizing these tools.
Should you consider a semi-closed exterior if you’re unsure? What are the benefits?

If you are struggling to decide between a closed exterior and an open exterior, consider a semi-closed exterior as an option.
A semi-closed exterior is a style that takes the best aspects of both open and closed exteriors.
Below, we will explain the benefits of a semi-closed exterior in detail.
Cost can be kept down
A semi-closed exterior does not enclose the entire property with walls or fences, but instead features a design that hides only a portion.
Therefore, it is easier to keep costs down compared to a closed exterior,
making it suitable for those who have just built a home and cannot afford additional expenses.
Improved security
As mentioned earlier, a semi-closed exterior combines the best features of both semi-closed and open exteriors.
You can enjoy the safety of a closed exterior while also experiencing the openness of an open exterior,
making it ideal for those who want to enhance security while also enjoying a sense of openness.
Conclusion
By surrounding your home with walls or fences in a closed exterior, you can enhance privacy protection and safety.
On the other hand, depending on the environment, it can sometimes create a closed-off atmosphere, making it difficult to truly relax in your home.
If you have such concerns, it might be a good idea to consider a ” semi-closed exterior ” that takes the best aspects of both closed and open exteriors.
