Are the costs of exterior construction high? Are there any tips to keep costs as low as possible? Kakeru Koumuten Co., Ltd. explains!

 

For those considering exterior construction,

“I wonder how much it will cost?”

“Are there any tips to keep costs down?”

you may have these questions in mind.

In this article, we will explain in detail the estimated costs for exterior construction and points to keep expenses low.

How much does exterior construction cost?

There are various types of exterior construction, and the costs can vary for each.

Below, we will provide a detailed explanation of the cost estimates by construction area.

Parking Lot Exterior Construction

The cost for parking lot exterior construction is often:

・Concrete installation → Approximately 150,000 to 300,000 yen per car

・Carport installation → Approximately 300,000 to 400,000 yen per car

This can vary significantly depending on the existing conditions and the thickness of the concrete.

One way to keep costs down is to use:

・Gravel
・Grass

However, this method is not highly recommended as it can cause dust to rise and may dirty the surrounding roads with mud.

If you really want to minimize costs, consider using concrete for part of the area to reduce material costs.

Fence Installation

The cost of fence installation is,

・Type of fence
・Installation location

It varies depending on these factors, but it is said that the average cost is around 300,000 to 1,000,000 yen.

In the case of a closed exterior structure that surrounds the entire house, the installation area of the fence will be larger, which will inevitably increase the cost.

If you want to keep costs down,

・Choose inexpensive materials (such as aluminum or steel mesh)
・Install only in certain areas

These are some strategies you can consider.

Gate Installation

The average cost for installing a gate is said to be around 150,000 to 300,000 yen.

However,

・Material
・Functionality
・Design

These factors can also affect the cost, so if you want to know the exact amount, it is recommended to get a quote from a contractor.

Exterior Work in the Garden

There are various types of exterior work for gardens, and the cost can vary significantly depending on the type of work performed.

For example, if you are just laying grass, the average cost is about the garden’s square meters × 10,000 yen, but if you want to create a more sophisticated garden,

・Planting
・Wood Deck Installation

These will be necessary, so it may cost around 1 million yen.

Installation of a Shed

If you are installing a shed in your garden, the cost for a small storage shed is between 100,000 and 150,000 yen.

However, if you are installing a simple garage or a relatively large shed, it may cost over 500,000 yen.

To keep costs down, using inexpensive materials is one option, but be careful as using materials not suited to the climate can lead to higher maintenance costs.

Installation of a Terrace

When installing a terrace such as a wood deck, it often costs around 500,000 yen in total.

If you use high-quality wood or install a roof on the terrace, the costs can increase significantly, so it is recommended to discuss this thoroughly with your budget before making a decision.

Installation of a Sunroom

The average cost for installing a sunroom is around 400,000 to 500,000 yen.

Of course,

・Window Size
・Functionality

The costs may vary depending on various factors, so it’s important to obtain an estimate in advance.

What are the tips to reduce the costs of exterior construction?

Next, we will explain in detail the tips for reducing the costs of exterior construction.

Carefully choose your contractor

To keep the costs of exterior construction down, it’s essential to carefully choose your contractor.

Contractors that can handle exterior construction include:

・Construction contractors
・House manufacturers
・Home centers

Among these, the easiest way to reduce costs is by choosing a construction contractor.

A reputable construction contractor will provide attentive consultations and offer suggestions to lower costs.

At our company, Kakeru Koumuten Co., Ltd., we offer free consultations for exterior construction, so if you’re struggling with choosing a contractor, please feel free to contact us!

Take your time to plan

Many people may want to request exterior construction at the same time as building their home.

In such cases, it’s necessary to start planning the exterior construction as early as possible.

This is because, in the case of new builds (custom homes), there is a deadline for the handover of the building, and if you start planning the exterior construction too late, you may not be able to meet the handover deadline.

If that happens, you won’t be able to choose a contractor that meets your wishes and ideals, and it will also be difficult to consider the balance with costs.

When building a new home, there are many things to consider, so it’s easy to postpone the exterior construction, but to achieve a satisfactory finish, take as much time as possible to plan.

Make efforts to reduce disposal costs for leftover soil

To reduce the costs of exterior construction, it is important to make efforts to decrease the disposal costs of excess soil.

“Isn’t that something the contractor should handle?”

I believe some may think this way, but there are contractors who lack the awareness to utilize the leftover soil and instead try to dispose of it as is.

Among such contractors,

they may charge the client for the costs in the form of “disposal costs for excess soil”.

The leftover soil can be utilized for:

・Slopes
・Flower beds
・Planting areas

By implementing such ideas, it may be possible to lower costs, so let’s carefully plan.

Only perform necessary construction

The costs of exterior construction are primarily made up of material costs and labor costs.

To keep costs as low as possible, it is important to focus on these “material costs.”

For example,

・Install only the posts without a gate
・Install fencing only in certain areas

By being creative in this way, you can reduce costs.

Obtain multiple estimates

When carrying out exterior construction, be sure to obtain multiple estimates.

This way, you can get a general idea of the market price for exterior construction costs, and

・Extremely high-cost contractors (likely to be a scam)
・Extremely low-cost contractors (likely to issue exorbitant charges later)

You will be able to distinguish such contractors.

Is it a mistake to focus solely on the cost of exterior work? What points should be prioritized?

While it is important to make efforts to reduce the cost of exterior work, focusing only on cost can lead to regrets.

Below are some points to consider beyond just cost.

Is there an after-service?

When undertaking exterior work, make sure to check if there is an after-service.

If there is an after-service, even if problems arise after the work is completed, you can have them addressed at no charge.

Some contractors may offer lower prices but do not provide after-service, which might seem beneficial in the short term, but if any issues arise, it can end up being costly, so caution is needed.

Do they have a proven track record?

When requesting exterior work, choose a contractor with a proven track record.

No matter how low the cost, if the quality of the work is poor, it is meaningless.

Most contractors showcase their past achievements on their company website, so be sure to check them thoroughly and only request work from those you can trust.
