I've included the prices charged us to help those who might be purchasing a new home. I've been told that a general rule-of-thumb is to add 10% to the cost of the house to account for the upgrades.
Our goal was to upgrade the items that made sense to have done during construction (extra rooms, hot water recirculator, whole-house insulation, etc.) and to take the standard options on as much of the rest as possible with the idea of doing those ourselves later.
The options came in three stages.
(Additional notes were added four years after we moved in.)
$ 125 BBQ Gas Stub at Rear Patio
(We never used this. It was placed in a poor location and was too small for use as the main pipe for the pool heater.)
$ 650 Wall/Door at Bath 2
$ 330 Wall/Door at Master Bath
$ 1,275 Sink with cabinets in Laundry Room
$ 4,995 Option Bathroom #3
$ 4,550 Air Conditioning
$12,500 3 Car Garage with Workshop
(Because of this option, we couldn't put in a downstairs bedroom. This is one aspect that this house is lacking.)

$ 110 Mirrored Light Fixture
$ 120 Beveled Mirror

$ 210 Brass Obscure Shower Enclosure
$ 820 Acrylic Block Window
Electrical/Lighting
$ 140 Holiday Light Package
$ 800 Ceiling Fan box with double switch (8 @ $100)
(The double switch isn't a necessity these days. Most fan manufacturers have remote controls that handle both light and fan. Or the fan takes one power-in, and splits it. The major need for this option, in retrospect, was to have them install a suitable fan box. These straddle the stud and can support much more weight than the basic, which is used for light fixtures only.)
$ 80 Dedicated external GFI circuit (for future spa)
(The circuit they installed was a standard 120V and we needed 240 for the pool equipment we eventually went with. This was eventually laid in-ground at the same time as the dedicated gas pipe. We did use the circuit for the relocated water timer and the spa controller so it wasn't a waste.)
$ 4,490 Wiring Package #3
-includes two fiber-optic, cat-5, and coax (RG-6) runs to all rooms(Considering the ease of use with wireless systems, I'd strongly question this purchase today. The only aspect I really like is the RG-6 runs for my satellite systems.)
$ 150 Extra network bundle to office (Bedroom #3)
Exterior
$ 170 Front Door Windows
$ 1,620 Gutters
$ 150 Exterior Lighting
Garage
$ 750 3-car Garage Doors, insulated, with windows
(Note the "insulated" - this is an issue we found more on below.)

$ 30 Extra Remote
Kitchen
$ 3,380 Maple Cabinets

$ 240 Upgraded Hi-Low Cast-Iron Sink
Miscellaneous
$ 80 Stone Fireplace
$ 700 Laundry Room Cabinets
$ 570 Bedroom #4 Mirrored Closet Doors
$ 240 Round Corner Bead on Sheetrock
$ 2,170 Interior Insulation (including between floors)
(We were upset to learn (too late) that this didn't include walls in the garage. We purchased insulted garage doors and this package thinking it would help keep the heat down in the garage. Don't assume...)
$ 420 Security System Pre-wire
$ 920 Hot Water Recirculation (pipes and pump)
(One issue: they didn't include the kitchen sink in the pipe chain. It's the only faucet in the house that doesn't get hot water instantly. I consider this a major flaw that should have been disclosed as part of the purchase of this option.)
