What is Exterior Construction? A Comprehensive Explanation of Types, Cost Estimates, and the Right Timing for Construction!

Hello! This is Kakeru Koumuten Co., Ltd.!

For those considering building their own home,

you may have the question,

“What exactly is exterior construction?”

It is important to think carefully about not only the building itself but also the exterior to create a comfortable home.

In this article, we will explain in detail what exterior construction is, what types exist, and what the typical costs are.

What is exterior construction?

Exterior construction refers to,

● Gates● Walls
● Fences● Parking lots

These refer to elements such as these, and the construction of these is called exterior construction.

Exterior construction is typically done at the very end of the home building process, and if the design is incorrect, it can result in a home that looks different from the intended image, so careful consideration is necessary.

What are the Benefits of Exterior Construction?

Next, let’s take a closer look at the benefits of performing exterior construction.

Acts as a Boundary with Neighbors

Exterior structures serve as a boundary with neighbors.

For example,

・Walls
・Fences

By building these,

you can visualize that

“the area inside here is my property, and the other side is my neighbor’s property,”

which makes it easier to prevent neighbor disputes.

Contributes to Privacy Protection

Exterior structures also play a role in privacy protection.

・Walls
・Fences
・Plantings

By installing these, you can effectively block external views.

Also Provides Security Benefits

By performing exterior construction, you can also expect security benefits.

By installing walls, gates, and fences,

you can create an impression of being “hard to enter.”

Providing psychological pressure to suspicious individuals can also be considered a benefit of exterior construction.

Is it True that There are Different Types of Exterior Construction?

There are three types of exterior construction:

・Closed Exterior
・Open Exterior
・Semi-Closed Exterior

Let’s take a closer look at each type below.

Closed Exterior

A closed exterior refers to an exterior design that surrounds the entire building.

Mainly,

・Walls
・Fences
・Hedges

By installing a closed exterior, you can clearly separate the inside from the outside.

The closed exterior is a representative style that has been used for quite some time.

It is easy to shut out the view from the outside, making it recommended for those who want to thoroughly protect their privacy.

However, since it surrounds the building completely, there may be cases where it feels oppressive.

When installing a closed exterior, be sure to check if there is sufficient space on the property.

Open Exterior

An open exterior refers to a style that does not surround the building.

As explained earlier, closed exteriors were common in the past, but in recent years, due to the increase in small lots, open exteriors without gates or walls have been gaining popularity.

In the case of an open exterior, the lower number of structures makes it easier to reduce costs and also shorten the construction period.

However, if you build a house in a busy area, you may be concerned about the view from the outside, so some form of privacy protection must be maintained.

 

Semi-Closed Exterior

Semi-closed exterior refers to a style that takes the best aspects of both closed and open exteriors.

“I want to protect my privacy, but I also want a sense of openness”

This style would be ideal for those who think this way.

Semi-closed exteriors achieve balance by:

・Installing walls or fences in certain areas
・Adjusting the height

However, since semi-closed exteriors are a mix of closed and open styles, they can sometimes create a half-hearted image.

To prevent such issues, it is important to design carefully and thoughtfully.

What are the average costs for exterior wall construction?

Next, let’s take a detailed look at the average costs for exterior construction.

Entrance Area

Exterior construction around the entrance includes:

・Setting up the approach
・Gate
・Gate post

The costs for these constructions often range from 300,000 yen to 700,000 yen.

Garden

The costs for garden construction can vary greatly, so it is difficult to make a clear statement.

This is merely a guideline,

Fence	200,000 yen – 800,000 yen
Block Wall	600,000 yen – 1,100,000 yen
Gravel	10,000 yen – 30,000 yen per 1㎡
Grass	5,000 yen – 15,000 yen per 1㎡
Wood Deck	200,000 yen – 400,000 yen
Planting	50,000 yen – 150,000 yen
Shed or Storage	50,000 yen – 150,000 yen

It would be good to refer to the costs above.
If you own a car, you will need a parking space, right?
When setting up a carport,

・For 1 car → 150,000 yen –
・For 2 cars → 300,000 yen –
・For 3 cars → 500,000 yen –

The above costs are a guideline.

When building a garage, the cost range is higher than that of a carport,
it may cost around 1,000,000 yen to 2,500,000 yen.

Points to Consider for Exterior Work Based on Timing

Finally, I will explain in detail the points to consider for exterior construction based on the timing.

Can exterior construction be done before building the structure?

Exterior construction is generally a process that takes place at the end of residential construction, so it is typically not done before the main structure is completed. However, since the exterior is an important element that influences the image and atmosphere of the house, it is necessary to plan it before starting the construction of the house.

Before starting the construction of the house,
・What should be placed on the approach to the entrance?
・How should we block the view from outside?
・How far should the parking lot be from the house?

If you carefully consider these points, the likelihood of completing a house that aligns with your vision will increase.

If you want to “move in right after completion,” it is also possible to carry out exterior wall construction simultaneously with the house construction. By starting the construction at the same time, you can synchronize the completion times of each, allowing you to begin living almost simultaneously with the completion.

Can construction be done after the building is completed?

Exterior construction is often the final process when building a house, and most people carry out exterior construction after the building is completed.

By performing exterior construction after the building is completed,
・You can only carry out the necessary exterior construction
・You can reduce financial burden, which provides benefits.

Summary

Exterior construction includes,

・Fences
・Walls
・Parking lots

It refers to things other than the buildings on the property.
There are closed exteriors and open exteriors, as well as semi-closed exteriors that exist in between, each with its own characteristics and advantages and disadvantages.
In any case, exteriors are an important element for achieving a comfortable living environment, so it is essential to proceed with caution. For those who are planning to build their own home or carry out exterior work, it is advisable to take your time to think carefully, using the information introduced here as a reference.
