SIPs vs Stick final costs

The total cost of the wall and roof framing, including insulation and vapour barrier, came to $3,458.  This level of completion is similar to what a SIP build would be.  Back in August 2013  I had estimated that a it would be $3,500, which makes me pretty bang on.

I would have liked to have built with SIPs but the $9,000 to $10,000 quotes where way too much money.  Granted I would have been finished the house by now.

All in all I'm happy with my decision to stick build.

More posts coming soon

I'll be soon back to work on the house but here is a little summary of the past 3 weeks.

First, I got a second quote for the SIPs and it was $9000 with taxes in, about the same price as the other quote.  As much as I would like to use SIPs, I can't justify spending and extra 4-5,000 on them.  Now I have to rework the plans to go with a conventional stick build.

Second, I spent 5 days on my motorcycle touring around Washington state and Victoria island.  It was awesome.

Third, I started school!

Finally, I sold my 28 foot toy hauler and had to drive it to Edmonton to meet the buyer.  With school and building the tiny house eating up a lot of cash the sale gives me a good buffer.

Two small updates.  I was given a second induction cook top for free!  I just bought a used 2500 pure sine wave inverter for 225!  Now I can run all the tools off the battery bank.

Why I did not build with SIPs.

I got the estimate back for the SIPs yesterday.  I expected it to be in the 3,000 to 5,000 range.  I opened the email and saw $9,200!!!! =O

This morning I called another company, they where nice enough to give me some numbers so I could ball park the cost.  This time it came to about $7,000 with a 6 to 8 week delivery time.  (Edit this second estimated ending up being $9,500)

I did up a spread sheet to estimate how much a stick build would cost.  I included sheathing, framing, insulation, vapor barrier and a large cushion. My estimate is $3500.

I love spreadsheets.

I've been using one to track my expenses so I just added a few numbers for the siding and windows to get my "dry in" price.  With SIPs I would be around $19,000, stick build $15,500.  Add on plumbing, electrical, cabinets and it starts to add up.  Granted I'll have more time to look for bargains which would help.

Delay on account of SIPs

I spoke with the SIPs company last Friday.  I was told the earliest I would be able to get the SIPs is the first week of September.  It took the wind out of my sails.  I didn't order them sooner because I wanted to floor mostly done so I could make sure my model matched what I had built.  Good thing too because the house is 1" shorter then it should be.

I also spoke with a company that provides wool insulation last week and still have not heard back from them.  I guess I'm going with fiberglass.

I spent the last few days mostly relaxing with family but I did finish all the flashing on the bottom of the trailer.  I also wrapped each of the outriggers in typar (like tyvek).

With the outrigger upside down

 And on it's side

The wasps have been really bad and the spray has not done it's job.  I tried to buy a wasp trap today but all the stores where sold out so I bodged together one.  I'll let you know if it works.

Expenses to date $5,761

SIPs

Having remeasured the trailer and tweaking the model I spent the morning exporting views so I could send the designs off to the company that will be making the SIPs for me.  After sending them off I started playing with the window sizes a little.  I'm trying to go with a size that is "stock" so hopefully it will be cheaper.
