About two and a half years ago we promoted Simpson Strong-tie's Wall Bracing Calculator. A new contender has entered the ring, APA (the plywood people). We played around with their new calculator and found it to be a little different than Simpson's. For one, the walls are adjustable more on the fly. With Simpson, you need to use their Java back button and re-enter inputs. With APA you can see changes as you go. The biggest difference is that you can enter each braced wall section and opening so that APA can calculate not only the total wall bracing needed, but each panel as qualifying or not. Pretty slick.
To play around with it, go here. You will need an account to access their website but it's totally worth it.
And make sure you save your work (as an XML file, very cool) before exporting to a pdf. The pdf feature is temporarily broken. *edit* PDF function fixed. But the xml feature tells me that I could edit the hard data in a text editor, similar to a Google Earth kml file. Take that, Simpson!
"200 Square Feet" our first ebook is now live and free for a limited time. You can find it on Amazon or check here for other international markets. Free promo period will end on Saturday at midnight PST (UTC -8:00). If you are interested in tiny house ideas, details, and designs, please check out the book. We've included over a dozen different plans for 200sf and smaller shelters. We've also set up a support website for the book. Of course, your referrals and reviews are highly appreciated. Send us your questions and comments!
For the last few months we have been busy writing. Not on this blog, obviously. All of our wordsmithing efforts have been going into creating an ebook on tiny home design. Several designs are being created to go along with the book. We are aiming for a Cyber Monday release. Standard price will be $3.99 for the book in either pdf or Kindle version. But during Cyber Monday week (Monday through Friday) we'll be introducing the book for the low price of free. For five days only you'll have the opportunity to see our content for nothing out of pocket.
What you'll get:
Ideas, some building theory, comparisons of construction types
What's not included:
Building on a trailer (plenty of others doing that), detailed step by step construction guide.
Stay tuned to this blog or use the subscribe feature on the right to be the first to know.
If you answered something like studs at 24" o.c., I'm sorry to disappoint you. The most common cause of wall sheathing buckling is because it wasn't properly gapped. We've hounded on this before. But now the APA has developed a mobile tool that will help educate builders on some of the most common building issues.

The City of Portland, OR recently announced that they have been able to streamline their solar application process. This means that they were also able to reduce the fees on a solar permit. Press release follows:
July 1, 2014.
Effective immediately, the City of Portland Bureau of Development
Services will be reducing the building permit fees for Prescriptive
Residential Solar Permits from $554 to $263, a 52% reduction. In an
effort to be responsive to the Solar Industry concerns about existing
fees and the City’s goal of encouraging more sustainable energy sources,
the Bureau worked with Solar Industry representatives in an assessment
of the current fees and associated solar permitting and inspection
process. This evaluation realized efficiencies in the permitting
process, allowing the building permit fees associated with solar
projects to be reduced. Separate electrical trade permits continue to
be required and their associated fees remain the same.
“We are hopeful that the reduction in building permit fees for solar
installations on residential structures will encourage more homeowners
to adopt this sustainable energy source, helping the City to meet
sustainability goals,” stated Commissioner Amanda Fritz. Bureau
Director Paul L. Scarlett added “This is a great example of where we
were able to work with industry partners to realize permit fee savings,
while maintaining cost recovery on the important life safety
and livability services the City provides through the building
Overall, the Prescriptive Residential Solar Permit fee retains cost
recovery levels for the Bureau, while achieving a level of review and
inspections that ensures compliance with applicable building, electrical
and land use codes. Field inspections will verify installations adhere
to approved plans, assuring safety and code compliance at the time of

The APA (those wood people again) have issued a report on raised heel (AKA energy) trusses. Typical trusses do not allow full height insulation out to the outside edge of an outside wall. This means that the thermal envelope of your house is compromised where the roof comes down to the wall. This would be akin to the back of your neck where your coat doesn't quite reach up to nor does your wool hat reach down to. So consider raised heel trusses to be a scarf for your home.
Builders harumph about several issues. Mainly plywood and siding and the extra cost. How much extra cost, Captain Pennypincher? Yes, it does cost extra. But could you perhaps use all those drops from your sheathing in that extra 8-12" space? But the taller blocking is also a somewhat valid point
The report gives some simplified methods for securing the trusses without complicated blocking. The report is applicable for trusses with a heel between 15-1/4" and 24"; using continuous plywood (CS) as a prescriptive shear bracing method; for homes in seismic zones A, B, and C; for homes with wind exposure of 110mph or less; a whole list of other fairly typical conditions.
In essence, plywood has been found to be adequate to replace blocking between the tall trusses for all but the top chord itself. That is, rather than using stacked 2x12's (illegal anyway) or a truss company built blocking solution, the plywood can extend to the bottom edge of the top chord. Typical 2x4 bird-blocking can be used on top of that.
Thankfully, you as a builder do not have to figure this all out. Talk to your designer about simplified solutions for energy heel trusses. Here at Istockhouseplans, we're always happy to help you get the most bang out of your buck.

First off, we apologize in neglecting this blog for the past several months. The promised new website has run into more roadblocks than expected. However everything seems to be agreeing with one another now. We still have a few multi-family and garage plans to add yet. And we have a couple of new plans as well, as mentioned.
The biggest change has been moving away from GoDaddy's hosting service and revamping the plans catalog to be more searchable by feature. Granted you can't pinpoint a plan that is 4000 square feet with 5 bathrooms (wouldn't be one of ours anyway). But with the exclusive number of fine plans we offer a single search term will narrow the plans down to a reasonable number. You might even find something unexpected!
Please take a few minutes and let us know what could be improved. While the new site is highly functional, we are certainly open to more functionality and ease of operation.
