HATOCOT®: 3 Reasons It Continues to be the Customers’ Choice

news | 12 March 2021
Tag: hatocot

by F.S.

Recently we introduced Hatocot® – prefab dog house – in the previous article.
The performance in Japan is almost unrivaled, its market share is over 90%.
What is the secret to the strength of this product?
This time I would like to take a closer look at its appeal.

1. Significant Reduction in Construction Period

The figure above is a comparison of the construction period of the conventional method of dog house and Hatocot®. When making a dog house, the conventional method requires multiple processes such as Formwork and Curing, but since the prefabricated Hatocot® is only installed when placing concrete on the roof, that time and effort can be saved. Based on construction works data in Japan, you can save 14 days!!
Even if the construction period is slightly delayed due to turbulent weather, it can be fully recovered.

2. Cost Advantage

No matter how much the construction period can be shortened, if the cost is too high, it will be difficult to use at a site.
Therefore, I tried to verify whether Hatocot® – prefab dog house – has a cost merit with the following comparison table.

By using prefabricated Hatocot®, it is found that the site management cost can be reduced because the construction period is shortened. This is also one of the great attractions for construction sites.

3. Sustainable & Clean


No wooden materials for assembling the forms are required for Hatocot® installation because it is a prefabricated and ready-to-assemble unit. Once you bring it in the construction site, it contribute to reduction in waste material.

Allowed to be used in Singapore buildings
After confirming with BCA in Singapore, we received a comment that authorization is not required to install Hatocot®. In other words, you only have to install it at the time of set up piping. As you can see, Hatocot® is a niche, but there is no doubt that it is an easy-to-use product.

Achievement in Singapore
Hatocot® – prefab dog house – has many benefits as mentioned above. Some Japan customers want to use it outside of Japan.
A typical example is Changi General Hospital, used for rooftop duct covers.

I believe by now you can see the charm of prefab dog house Hatocot®.
Finally, we would like to inform you of the special promotion.
By application by June 2021, V-II type will be offered at a special price on a first-come, first-served basis.
Please apply as soon as possible through the inquiry form in our website.

We are looking forward to your applications!
