Like the other answers, it depends if an investment property or personal residence. However, even if a personal residence you do not want to over build or put in items that are above the market. The reason is that when you go to eventually sell your house you do not want to be the most expensive or unique home in the neighborhood. You want to fall right in the middle. This way you will have the largest number of potential buyers looking at your home. You can never go wrong staying on the conservative side.
