Then your example should have been “this house is aesthetic”. Aesthetic is being used as an adjective.
Saying “this house has a pleasing aesthetic” is correct. Aesthetic is being used as a noun. “Pleasing” is the adjective. While the aesthetic is not defined enough to your liking, it isn’t being used as an adjective.
Use your original wording and replace the word “aesthetic” with the word “quality”. “This house has a pleasing quality” is a proper sentence. Sure, there’s ambiguity as to what that quality is (is it the shape of it? Is it the color? Perhaps the landscaping?), but it isn’t grammatically incorrect.

The commenter was telling you how they use it, not giving an example. The commenter told you what the adjective means.
