Icons like houses on trademarks may refer to different brands. Here are two examples:

1.Arc'teryx (Archaeopteryx): The trademark of this brand is a triangle like a house with a bird-like pattern in it.

2. North: The trademark of this brand is a mountain pattern like a house with a "T" in it.

In addition, some other brands also use icons similar to houses as trademarks, but there is no obvious connection between these brands.
