As i sit here and yawn I wonder why I am still up?

Goodnight!

After finding this statement on thesites, it makes me wonder why people would spend the money and not put them together on their own?

Q. Why aren’t HVAC, plumbing and electrical details included? A. Because local HVAC codes, climatic requirements and commonly used systems vary dramatically throughout the country. Also, we don’t know which direction the water flow will enter your house or where the electrical feed will enter. Your local HVAC contractor, plumber and electrician can determine the best layout for your new home.
