stereoscopic viewing
adding depth to 3d images has long been the holy grail of 3d modeling
We have all experienced stereoscopic images. We have stereoscopic vision, so everyday sight is what I am talking about. The few inches between our eyes provide a slightly different view point. For any given surface that we see one eye sees a little bit more or a little bit less of it. While the difference is very slight it is sufficient for us to judge distances in 3d space. This is something we have not really been able to capture when we do drawings. While we have gotten pretty good at depicting 3d space the images don't create the sense of relative depth that our two eyes provide.
There have been many attempts to provide this vision to flat images, and we are pretty familiar with them I'm sure. With the advent of photography early on there were efforts to make 3d images with special viewers and cameras that took two images with the required offset. We have probably used a "View Master" image viewer which worked on the same principal. I'm sure that you have tried a blue/red filter glasses to view images or movies in 3d. These rely on the filters to deliver the proper image to each eye. More recently this has been done more effectively with polarizing filters on the projectors and viewers glasses. Sometimes the effect can be achieved by simply staring into the distance with the respective images directly in front of each eye.
The two images below are such stereo images, each slightly offset from the other.
Another way to put the images together into a 3d view does not require you to feed the right and left images discreetly to each eye. Its been found that if the right and left images are presented sequentially, alternating in the same space that your mind will read the spatial depth in a similar manner. If you click on the images above such a sequencing will load. The depth of field in this image will exaggerate the effect - it will look a bit like an earthquake but nothing that will make you nauseous!

This gives you a good idea of how the spaces step down the hill and are interconnected. The next photo is from the guest room at the entry level in the front looking back towards the living room at the rear and the master bedroom above.
And the exterior, the front of the house next:
and then the side, you can clearly see the hill side here:
and finally the rear which overlooks the small stream and the garage and pavillion beyond.
Thoughts and questions about the house are welcome. I want to convince Peter to do the work required to offer this as a stock plan.
One thing I have not discussed relative to this instance of the Tray House is deviations from the plans. These things are immediately obvious to me, and I assume the design savvy readers here will also take note of these things. Deviations are going to be par for the course with stock plans and I don't really regard them with any criticism. I think it is valuable to consider the fall out of these changes however as they can have a ripple effect. If you think these things through you will know better how they affect other parts of the design. Sometimes these issues are purely technical, and sometimes aesthetic, but they tend to get tangled together.
For example the builder of this house used roof trusses rather than roof rafters to frame the roof. That in of itself would not necessarily cause other changes, but somewhere in the process a decision was made to support the trusses that were above the bay windows on a header above the window rather than a beam spanning the entire bay window opening at the wall as specified. What this did was create a variety of span points in the trusses which I am guessing make it easier to make the trusses with the bottom cord extending all the way out under the eave. This created a horizontal eave where the design called for an eave that followed the roof slope. It also required headers to carry the roof load above the bay window units which now had to be pushed downward, almost to the floor to make room for them. Small decisions can propagate little changes in this way. We can always help you to think them through so you are satisfied with changes that may result.
