When considering a house demolition, it is natural to wonder how much it will cost. In this article, we explain the typical demolition cost range for a 50-tsubo house by structure type, along with practical points for keeping costs under control.
How much does it cost to demolish a 50-tsubo house?
Demolition costs vary significantly depending on the building structure. As a general guide, the cost is about 1.25 million to 1.75 million yen for a wooden house, about 2.0 million to 2.5 million yen for a steel-frame house, and about 2.5 million to 4.0 million yen for an RC house.
Wooden house
The unit cost is about 25,000 to 35,000 yen per tsubo, so for 50 tsubo the total is approximately 1.25 million to 1.75 million yen. The work usually combines heavy machinery with manual demolition, but on narrow sites manual work becomes the main approach, which raises the cost.
Steel-frame house
The unit cost is about 40,000 to 50,000 yen per tsubo, so for 50 tsubo the total is approximately 2.0 million to 2.5 million yen. In older buildings that contain asbestos, the cost can in some cases approach 3 million yen.
RC house
The unit cost is about 50,000 to 80,000 yen per tsubo, so for 50 tsubo the total is approximately 2.5 million to 4.0 million yen. Costs may increase further if oxygen burners are required.
Regional variation
In Tokyo, the unit cost for RC structures is around 60,000 to 80,000 yen per tsubo, while in regional areas it may fall to 40,000 to 50,000 yen. Be sure to obtain a quotation to confirm the actual cost.
What other costs are involved besides demolition work?
Incidental work costs
These include the cost of removing garden stones and trees, carports, block walls, and similar structures. The more items there are to remove, the higher the overall cost will be.
Buried object removal costs
These are the costs of removing underground garbage, waste, wells, septic tanks, and similar items. In some cases, they are discovered during demolition work and create additional charges.
Asbestos removal costs
Asbestos removal alone may cost anywhere from several hundred thousand yen to several million yen. Older buildings require a prior inspection.
How can you keep demolition costs down?
Obtain quotes from multiple contractors
By comparing multiple contractors, you can find one that offers a sound balance of reliability and price. However, you should be cautious about quotes that are unusually low.
Remove and dispose of household belongings yourself
If you ask the contractor to dispose of leftover belongings, the cost can become quite high. Handling disposal yourself can reduce the total cost substantially.
Use municipal grants and subsidies
Depending on the municipality, you may be eligible for subsidies worth several hundred thousand yen. Check in advance with your local government office or demolition contractor.
Summary
Demolition costs vary widely depending on the structure and region, but it is possible to reduce expenses by comparing quotes in advance, disposing of leftover belongings yourself, and making use of subsidies. Plan carefully to avoid unnecessary costs.
