I'm going to blow in cellulose for the ceiling insulation. I would recommend stapling a vapor barrier between drywall ceiling and cellulose. I used fiberglass and if you buy their (home depot) minimum 8 packets they loan you the machine to blow it in. Very easy and fast. Don't seal off the vents, they sell something you need for about $2.50 you can put every 8 feet, so that your attic is not sealed off.

I have done some home renovations that cost upwards of 30k, which included new HVAC, service drop, re-wired electrical, quality flooring, new kitchen, new drywall, insulation, used appliances. I am hoping to build a new home sometime in the next couple years around 700-1000 ft^2, and will have no less than 40k set aside. I will need to have my residential contractors license first. Permits and inspections are a hassle, but worth it from a selling standpoint.

The entire house envelope will have a vapor barrier under the sheetrock

That is tough--my bid for the well and the septic was about $10,000. The well only has to go 90 feet down and it is a regular septic no lift or mound.

www.nansulate.com and look at Phase Change Materials [PCM] Smart Boards by BASF are available here in US but pricey $400.00 a sheet compared to $24.00 for rock sheet, best to get the chemistry and apply it yourself. Salt based not good for metal, paraffin wax based without wire mesh. They have controlled the problem of fire with the wax.
Use them where you spend most of your time do not use them for the garage where you would waste energy. As for Americans we love waste that is why EU is ahead of us when it comes to building envelopes.

Other PCMs for heating when you do not need cooling as in changing of the seasons and where or country you reside. Tropics or Freezing.
That small of square feet would make your house or reduce 60% in energy costs. Should have it paid off in 3 years in upfront investment.
Best to use Insulated Concrete Panels or insulated block system with the added above materials: 80% energy efficiency. Solar panels for heating as well as electricity. Not EPS made ones but embedded into the matrix.
Each state/county is different in material costs [imported or on site] as well as production and assembling building materials. China’s cement is cheap[was]; it is imported to the west coast. Sand 80% comes from British Columbia, Canada or Mexico. Mexico also supplies cement to south -west region of the US. As for the sand have not kept up with news if Mexico is importing sand to lower basin [Los Angeles]. That was not the case years ago when Mexico did not import to L. A for tariff agreements or some stupid reason because of L.A. Brought the price of sand $$$$.
