Well, here we are deciding what the inside of the home will look like. You can see the layout on the blueprint but you may want to make a few minor changes. Let us look at what we can do to make things easier.
Now that the framing and the roof are up, the electricians will be coming in to wire your home. Here are a few things that you may want to consider. If you have large rooms, you may want more outlets available for convenience. I put two (2) outlets on each wall. No matter how you arrange your furniture, you will have an outlet nearby for any short-corded appliances. I had a cathedral ceiling in my formal living room and in the foyer. Above the door, in the foyer, was a window that you can only reach with a tall ladder, not a stepladder. I made the electrician put an outlet below the window just in case my wife wanted to put one of those candlelights on the sill for decoration. What is one more outlet at this point?
I am jumping the gun here, but I will talk about the fireplace mantle. My mantles were made of oak but they were hollow because I had the electrician put two (2) outlets on top of each one incase we needed lights on the mantles. Now we can eliminate those long cords across the room to an outlet.
If you love ceramics and you use a kiln to fire your pieces, you may want to add a 220-volt line in the basement for that purpose. I did that too. While in the basement, think about how you will use it. If you want a small workshop, you may want to put outlets above in the floor joists so you can hook up fluorescent lights for good lighting. Even if you do not want the shop, at least make sure you have quite a few outlets available on the walls for future use. Have it wired now before you refinish the basement and the cost won't be as harsh later.
Make sure that your contractor has a separate circuit for each of the following appliances. This way you won't overload the circuit when you are running multiple appliances. The stove (if it is electric) is a 220v line, the microwave, the dishwasher, and the refrigerator. The garbage disposal is questionable. Have the electrician check the data on the manual that came with the unit. In your mud room or utility room, you will need a 220v line for your clothes dryer and a separate line going to the washing machine. All these appliances are very important to be independent of each other. There should also be a line for your stove hood for venting cooking fumes. Your electrician can calculate which appliances can operate in tandem without tripping the circuit breaker. I would insist on no more than two (2) appliances per circuit if they won't exceed the amperage limits. Ask the electrician if starting an appliance, while another is operating on the same circuit, will spike the current. Spiking the current for just a second can trip the breaker. If it is capable of that short burst, then you may have a problem. I hope your electrician is smart enough to understand that phenomena.
Your floor will be done later after the dry wall is completely finished. Your fireplace should be in process. To better understand the energy savings of a fireplace, you can read my article on "Fully Functionalize Your Fireplace With More Heat". The only comments I have are what I did in my home. You can decide what is best for you. My living room and family room were back to back. I had two (2) fireplaces back to back, but they were staggered and not directly behind each other. Since my fireplaces were on the inside wall, I had a small door put on both sides, next to the fireplaces and adjacent to the outside wall. The reason for the idea was to have a place for your firewood, easy access and the wood is hidden from view. These doors were back to back. However, inside the storage area, I had another door (insulated) that opened from the outside. I had my contractor put a keyed lock on the outside of that door for safety purposes. Now my wife couldn't yell at me for carrying wood through the house and make a mess. All I had to do is put the wood in from the outside and that solved my problem.
Because I had two (2) fireplaces, I needed two (2) flues. That was in the blueprints. I thought about it and I figured that if my home were total electric, what would happen in winter if the electric went off because of a huge storm. It was then I decided to tell my contractor to put in a third (3rd) flue. I told him to make it go to the basement. My reasoning was that on a brownout, I would have a woodstove downstairs and both fireplaces on the main floor. That should keep the house warm enough until the power was restored. My contractor even asked me to design the chimney, which I gladly did. He knew by now I had the talent to change the design safely.
