What Kouken Kougyo can do.
Kouken Kogyo is engaged in a wide variety of businesses.
-
01
Interior demolition (skeleton construction)
All partitions, columns, ceilings, floors, and other artificially attached non-structural elements are removed, leaving the interior empty. All electrical wiring, exhaust ducts, air conditioners, and other related equipment are also removed, leaving only the interior space, which in the case of a reinforced concrete building is left as bare concrete. The major advantage of this project is that it can be completely renovated, including convenience and design aspects, and the construction work can be large-scale.

02
Wooden Demolition
The cost and process of demolishing wooden houses vary depending on the building method and environment. Sometimes, hand tools like crowbars are used instead of heavy machinery. We also manage the surroundings by using soundproof sheets, spraying water to control dust, and thoroughly cleaning the site daily.

03
Steel Frame Demolition
Steel construction uses steel frames like columns and beams and is divided into “heavy” (6 mm or more thick) and “light” (less than 6 mm thick) steel frames. Heavy steel is used for large buildings, while light steel is common in houses and small stores. Demolition costs typically range from 30,000 to 40,000 yen per tsubo, but vary based on the type of steel frame.

04
Reinforced concrete (RC) demolition
Reinforced concrete construction is highly durable, fire-resistant, and strong, with steel and concrete compensating for each other’s weaknesses. This makes it very sturdy and hard to demolish, requiring special methods like the “crusher” or “large breaker,” leading to higher demolition costs than wood or steel structures. As demolition is a large-scale project, precautions must be taken to minimize noise, vibration, and dust affecting the surrounding area.

05
Asbestos removal
When demolishing a building, it is necessary to investigate in advance whether asbestos (asbestos) is used. In addition, removal work requires notification in accordance with laws and regulations, protective equipment such as full-face dust masks, and the use of disposable work clothes. Be very careful of illegal installers, because if they do not remove the materials correctly and they scatter, they can be a health hazard not only to the owner and the people who live there, but also to the neighbors and many others.

06
restoration work
Restoration work refers to removing renovated fixtures and fittings and returning the property to its original condition when vacating a leased property such as an office or a store. Although it depends on the content of the contract, in most cases, the contract stipulates that partitions and other facilities installed for the tenant’s convenience must be removed and returned to the lessor. First, it is necessary to confirm the contents of the lease agreement and discuss the scope of restoration work with the lessor.

07
Parking lot removal/new construction
All partitions, columns, ceilings, floors, and other man-made attachments other than the structure are removed, leaving the interior empty. In the case of a reinforced concrete building, the interior will be left bare of concrete. The major advantage of this method is that it allows for a complete renovation, including convenience and design, and the construction work is also large-scale.

08
Antique Purchasing
We are licensed as an antique dealer and will purchase valuable items left behind by residents. If we find items that can be purchased, we can reduce the cost of disposal while reducing the amount of leftover materials. In addition, demolition produces a very large amount of waste, so by being part of this kind of recycling, we can help reduce the amount of waste generated. We welcome requests from individuals as well as from the real estate industry, demolition companies, remodeling companies, and estate liquidation companies.

09
Purchase of valuable materials (scrap)
Metal waste and other waste may be sold for value. We strive to reduce waste by selling electric wires, aluminum, scrap iron, etc. generated during demolition as valuable resources and recycling them. By properly disposing of waste, we help our clients manage their waste, reduce disposal costs, and improve their corporate reputation. Please feel free to contact us if you want to dispose of scrap but do not have the means or time to transport it.
