Depending on size of project & CofO requirements 2023 looks optimistic using large crews of pros & all finishes already in transit to your site

Completed drywall is usually the "1/2 way" point in a custom home.

I think there is a law in physics that states, "For each lineal foot of drywall seam mudded, there is one less lineal foot of drywall seam to be mudded." Or something like that.

"Keep On Trucking" was another popular one during the late 60's.

OMG! It is money well spent to hire a crew, they you can paint.

Post on the monthly Building threads. Several people have built their own houses and might pop in with some advice.

Here is the September thread:

Yeah my beautiful man n me know that feeling. We are building our retirement home. Not the fifirst home I've had to build myself. We lost our home in a forest fire and had to rebuild. Keeping the correct attitude is hard but makes the job easier. I like listening to music so iI'll crank up some tunes. Make yourself stop once in a while. Maybe have a cold beers.

If you think about the value that you will have in your home after your done you paid yourself pretty well. Taping rock is a big job and you have a huge job. Big house.

It will get done and something tells me that your going to be having Christmas there either way.

There's a win in everything

As gently hinted to upstream, quality drywallers minimize the joint and drywall sizes. In one home I built, they used 12 footers where possible. The less skilled the sub, the more of "the tapers will fix it all up" rhetoric you will hear.

Hopefully, you had skilled trades do that complicated roof with so many angles and connections practically praying for water infiltration.

You need a professional drywaller to finish those seams. If you think yours look badly now, wait until you prime and paint.

I am afraid you are not going to be able to get the finish you desire with the drywall work that as been done. Look at the shadow on the stairs showing the difference in plane of the 2 adjacent pieces. That can't be fixed with tape, mud, paint or an exorcism.

Believe me, I feel you on the doing it yourself, exhaustion, frustration, wanting to be in by Christmas, etc - but you have to know when to hire out. This is one of those times.

The skill required to do this well (and that frankly is to HANG the sheetrock and then FINISH it) can't be replicated by the homeowner doing it for the first time. Framing, in fact, could have if you had good drawings - because it requires squares, levels, etc - you can be a good framer if you are anal retentive and follow directions, etc. Mudding requires muscle memory to get a good FINISH (and that all starts with good sheetrock hanging... on square and plumb walls...)

For your sanity, hire pros to finish those walls. It’s like 5 acres of wall. You will go nuts.

Hire pros to rehang most of that. It will finish out like a rough day at the beach. You will have to have a pretty heavy texture to disguise all of that. All of that translates to no finish product fitting. That means a ton of shims for cabinets, and a 5 gallon pail of caulk and backer rod per room for any trim.

I would take a step back and try to be realistic about timeframe and what is left in order to take a bit of stress off. As others have said, finished drywall is typically the halfway point of building a home. I would plan on at least another year before you're done. If you don't have a large crew, things will take longer. Flooring can take a month or longer. Range with electrical outlets, switches, and lighting. Finishing that drywall will likely take a month or more (and as others said, you should seriously consider hiring professionals for this, and I would guess it would still be weeks of work for them). Now may be a good time for a reset to consider what you can do yourselves versus hiring out, considering budget, schedule, etc. Getting some clarity on what's realistic to accomplish might help get you unstuck...

The schedule is very much driven by the size of crew. For example, some builders around here can build a 6,000 sq ft custom home in less than a year from ground breaking to occupancy, but it's because they have very large crews that tackle each step of the build. You'll see many trucks on site each day, sometimes 10+, and some will work weekends too. In contrast, other builders can take longer to build a 3,000 sq ft house because their subs have smaller crews. For example, consider how long it would take a drywall crew of 2-4 people versus one of 8-10. Both might do equal quality work, but the larger crew will finish much faster. I suspect the builder is paying more for these large crews to be available based on his schedule, but it gets the job done fast when few expenses are spared. Putting this into context, as a non professional, your combined productivity might equal one professional. It will take a long time to get things done, but if you accept that, then that's ok.

Maybe my knowledge is dated but the drywall around the windows looks incorrectly hung. i was always taught not to have seams in the lower corners, that instead the drywall should wrap the corner in one solid piece to avoid future cracking.

This is what a professional drywall mud and tape job looks like. Compare it to the 5th picture please.

I'm no drywall expert, but we have built 2 homes. What catches my eye, is that you seem to have used too many small pieces of drywall, like you were trying to maximize material use and not to minimize the number of seams.

Most likely a well staffed & organized pro with everything in transit would still take 5-6 months but I see some taking a year from this point. DIY likely 12-18 months.

T T makes some good points about size of professional crews vs schedule but it takes more:

All your decisions should be complete w orders placed at drywall. Understand the supply chain is still thin and that custom home finishes are often not commodities.

Prior to drywall cabinets should be in process, tile ordered, door & trim ordered.

When drywall is textured doors, trim and painted closet materials should be delivered & installed. Special ceilings installed. Shower finishes can be completed concurrently.

The home can then be painted prior to cabinet install (or after).

Install cabinets, complete tile flooring, counters & splashes

Install enclosures & mirrors, start finish plumbing & electrical

Stairways can go in early after trim & tile work is completed upstairs if threads can be protected but this process will restrict access during.

Meanwhile exterior should be moving thru flatwork.
