Half-block related

I used Google Translator.

I am a member of an architectural group.
What we always thought of was half a block of concrete or half a block of wool.

But when I think about it
I would like to add one category to the half-block itself, and add all the blocks and, if not possible, the half-blocks of various blocks to the half-block category.

Conclusion: Adding a half-block category to add various half-blocks Example) Concrete half-block, wool half-block

But if it's difficult to add categories
Please put in half a block of concrete..
It's very stuffy...

Thank you for reading the long article.
