Add one adjective for strength to improve your writing.

Write just one adjective in the part of the sentence you are interested in, so as not to dilute meaning.    

Say “The new product was built at the Riverdale Factory” if we want to explain the product is new.  

Say “The product was built in the modern Riverdale Factory” if we want to say the factory is modern. 

Don’t say “The new product was built in the modern Riverdale Factory” because attention falls neither on the product nor on the factory. When you want to emphasise on everything you end up emphasising nothing!
