Seeking a builder for a detached garage, backyard deck & “plunge” pool.

Hey everyone. Partner and I are seeking some recommendations for Houston builders that can handle any or all of the above. Just not sure if it’d be three different companies or if it could be a one-stop-shop kinda deal. 4,000ish sqft backyard.

I was imagining a company that could come see the backyard and do up some kind of a (cad?) drawing, then make it a reality?

We’re open to design suggestions, just not sure where to start or who to call.

Thanks for any input you may have and have a great one!
