Practice low-carbon concepts and build a beautiful home. Is this sentence a duality?

No.

The related words in the upper and lower sentences have different parts of speech.

Low carbon is a compound word with a broad connotation. And beautiful is a simple adjective.

The concept describes an abstract concept. Home is a concrete concept.

Philosophy and home are not compatible enough, while low carbon and beauty are completely inconsistent.

It’s called a parallel sentence at best.
