Hardwood floor designs Hardwood floor designs vary in the layout depending on the intricacy and what the customer wants. All installation of the design is done from scratch, meaning that the designs usually could be bought already done up and ready to install. Getting designs already made up are quite expensive to purchase. I like a challenge so that's why I make the design using regular hardwood strips. All designs are tongue and grooved so that no face nails are showing. The price of design work varies. Usually I charge by the hour + the square footage.
