We just built our house a year ago, and after living in it for a year here are some changes we are making:
We could not afford a walk out basement, so have a subfloor. It was NOT insulated (we put in real hardwood floors - Australian Cypress, GREAT FLOOR). This spring we are crawling into the space and insulating! We have an electric heater and our bill went up to $600 this winter
(normally about $120) We are also installing a wood burning stove to help with heating.
Upgrade to good quality counters. We bit the bullet and put in granite countertops and LOVE them! You can cut on them and not damage them, drop stuff on them, and they clean so easily!
If you think it is big enough, go BIGGER! We thought our house was going to be big (it is 2000 square feet), but the rooms are still not big enough for the kids. Also, our garage was supposed to be a two car garage, but we can in no way fit two cars in there (well, an explorer and f250)!
One of my favorites; our sliding glass window faces east with a patio. We can go outside and sip coffee and watch the sun rise over our cattle (when they are in the east pasture!).
Windows, windows, windows! I can walk into any of our kids rooms and look out over our property and see our cows, VERY NICE!
If you use a subcontractor to do any work, DO NOT PAY THEM until they COMPLETE THE JOB! (personal experience here )
Research your appliances and what you want to use; electric, propane, natural gas, .... We have an electric water heater and wish we had planned for a propane. Kids use up hot water after just two baths and it takes awhile to reheat. Dryer is gas and dries REALLY fast! LOVE IT!
UTILITY ROOM! We put ceramic tile in the utility room, which comes from the garage, and has a bathroom and sink so when we come in from working with the cows and horses we can pull off muddy boots and clean up before going into the house. Leave the muddy boots in the utility room. And we actually took the door off and put in a pet gate so the dogs get locked in the utility room when we are not home and can get locked in there when they are muddy and not get the rest of the house dirty!
Plan ahead! We had our barn pad cut out (120 feet x 60 feet pad) while the large equipment was here. We hope to build our barn by next year, but use the pad to store hay and have pens set up for working cows.
Just a little to start with. We love our home, just wish we had looked at more places before we built so we could get a good idea of how big or small it was actually going to be.
