It offers excellent ideas for lighting, creating extra space and electrical.
Here are a few other suggestions:
Lots of outlets. With my last home, I made sure I had strategically placed outlets and light fixtures. Some builders offer packages and some let you pick and choose how many and where they will go.
The 220s. Absolutely have at least one 220 located in the garage (that is in addition to the kitchen and laundry room). A few 110s are good, too.
Outdoor outlets and fixtures. Have a covered outlet installed for the front yard and back yard. You might coordinate your electrical needs with the outside lighting that fits your lifestyle. If you're the Chevy Chase type who needs to light up the entire county at Christmas time, now's the time to install that extra outlet.
Energy savers. Florescent is good for laundry rooms, basement work areas and a few other places where you're going to be for short periods. But lavish on lighting for dining rooms and kitchens where you will be spending most of your time. The builder's designer or the builder will tell you the kitchen is definitely where you want to spend any extra cash.
While you're at it, you might want to investigate installing a thermostat that communicates with your computer. Smart homes are here.
