Hollander House
-
And a couple more:
-
Nice blog and nice images Chuck. I look forward to seeing more.
-
Thanks for your kind words and interest! Plenty more to come, I promise.
-
looks promising... whence the name?
as a true Hollander myself, I see mainly lots of concrete around here...
-
-
I just posted the initial floorplan up on the blog. While the final version would be significantly bigger, the overall configuration will change little over the course of the design development.
-
Here are some videos to take in; I have in depth descriptions on the blog.

This was the first formal proposal we made to the Hollanders. As you can see, we have not even addressed the timber frame yet, as we are still nailing down the footprint and square footages.
The main roof is 6:12 and the central "crotch" is a very low slung 2 11/16:12. These pitches would propagate through the design revisions and would remain unchanged from here on out.
This animation also shows the correct site topography and how the house, with its walk out basement, would integrate with the site. The topography was constructed by tracing over a topo map with a vector software, bringing the vector topo loops into Sketchup, pulling them to the correct height and then skinning the whole thing with the sandbox tools. Last step is to apply a high resolution satellite image to the mesh.

This is the final configuration for the Hollander House, with the timber frame design finalized.
I highly recommend choosing the 720p HD version of the video if your internet connection is quick.

Here is the completed main floor timber frame. As you can see, it is virtually identical to the model.

Well, even though it feels like I am talking to myself here, which is a bit surprising since I thought everyone liked to see real world projects that came from a Sketchup model, but, oh well, I shall continue to forge forward.
These videos show the Kitchen Ridge System for the Hollander House. Since this house was designed around a mathematical grid that mirrors itself around the center of the bressumer beam, the Bedroom Ridge System is identical to the Kitchen system. This helps speed up the fabrication, as well as letting us remember fewer numbers of truth.
Each Ridge System is comprised of 4 posts, 3 ridges, 3 knee braces, and one capital.

No Chuck, I am following this topic with interest - however as I am not an architect/constructor myself, I really do not have much valuable to add.
There have more than 600 views of the topic though so I guess others are also listening. -
Hi Gaieus, thanks for taking the time to post. And I highly doubt that you have nothing valuable to add
You know, it takes a lot of time and energy to compile all of these clips, get them uploaded, compose the posts, etc etc, and, sometimes, a small note of encouragement goes a long way towards making it all worth it.
-
OK then, please, feel encouraged to go on with them!
-
Yes! Keep posting, I am following keenly (and on your blog as well)!
-
Hey Dozer, thanks for the kind words. I will, of course, continue with the story.
The bastard valley system is the next subject I will be discussing.
-
We are now moving on to fabricating the bastard valley bent systems, of which we need two, mirror-imaged.
I go into some detail about how we fabricated the system on the blog, of anyone is interested how we go from a computer model of truth (theoretical perfect, or theo) to actually putting wood together correctly so that these systems integrate with all of the other systems we are fabricating before any complete assembly happens.
The bastard valleys connect the 6:12 main roofs with the 2 11/16:12 pitch between the two bastard bents (where the purlins are). THe bastard valley itself is a 35' long tapered octagon, going from 15" to 12" diameter at the peak, and it sits on 5 different bearing points, which, if anyone has ever cut a beam to sit on three bearing points can attest, any deviation from height on nony of the 5 points would cause significant problems throughout the build.
Please note how we have 10 timbers all integrating with each other and sitting on one post; yes, we are gluttons for punishment as the precision necessary to ensure that everything fit together was off the chart. There was no margin for error, and I am talking about 1/32"'s over 35' long timbers.
I hope you enjoy!

Have to admire the precision of the work.

Thank you much for the kind words, and for taking the time to post them!
I don't know how we would have pulled this off without Sketchup, that is for sure. Having "truth" to constantly refer to was critical, at least for me. Having to cut a multitude of systems long before any actual assembly of the structure would have made me much more nervous if I couldn't double check everything under the sun with SU.
One of the nice things about this design is that it is a mirror image of itself around the center of the bastard system and there is a mathematical grid that underlies the bearing point layout that gave us a ton of reoccurring layout numbers that we could constantly cross reference and check from different places.
Almost nothing is more satisfying that laying out a timber that was in another system setup months ago, and, when placed in it's new system, all the theo lines from the first setup layout perfectly with the new one. That is the sort of thing that brings a smile to my face!
Sketchup and lasers are a potent combo!

Now that we have cut the bastard valleys into their respective bent systems, it was time to get the jack rafters and purlins scribed into the valleys.
In order to accomplish this, we needed to place the bastard valleys in space, place and scribe in the purlins, place and scribe in the two ridges that the valley peaks will bear on and then place and scribe in the rafters.
To place the valleys correctly, I used SU to generate elevations for the centerline of each bearing point under the valleys. Using this information, we could construct a temporary cribbing system that would support everything and allow us to micro tune the placement. Of course, not only the elevation needs to be correct; the spread between the two has to be correct along the entire length and the butt ends need to match up with the wall layouts.
