So what your asking is basically if i am understand you is how do i construct on a uneven surface
Well you could draw the house first but in that case you would be missing a lot of the detail of the terrain which determine what behind and what in front in term of perspective. You would also be missing alot of the proportional cue that help determine if the building is the right size. The easiest way to determine a complex subject is a box or a collection of box to plot the proportion first and then from those box create more complex construction within the bounding box. Personally i don't have much experience with such complex environment but from what i have gather about how other artist process and and what seem logical is doing simple box first to establish proportion but first you draw the terrain ruffly to determine WHAT overlapping WHAT this will save a lot of time if you know what you are doing.
What they are basically doing is using parallel line as guide by creating set of parallel line you start to have ''guideline'' that goes toward the vanishing point those line are ''reference'' that help you construct any form regardless of the perspective. You also have to find the ground plane otherwise you won't be able to determine how the terrain ''intersect'' with the building. This is more difficult on organic shape because this is no longer a very predictable plane on which you construct and it involve more complex intersection specially when done over rounded surface.
Here a demo i think will help you understand uphill perspective if that what i understand your referring to i personally refer to it as uneven terrain from a low or top down view.

My advise regarding everything perspective is to get Scott robertson book-
Drawing and sketching from imagination with scott robertson.
I also given you an example of a house build on what seem to be a uneven terrain. Note i say seem because if there an overlap you don't necessarily know how the terrain is behind that obscuring shape nor doesn't it matter much if it on a flat or uneven surface (unless you are thinking about physic) because what matter is do we see or not the form intersecting. What matter primarily the order of form overlapping since it hide what behind itself (sometime you have many overlapping form so understand the order of what in the foreground vs background also matter to determine what hide what).One other concern is does that overlap hide the intersection of the ground plane of that object partially or completely. If it partially that where the trouble begin. Because now you have to deal with overlap and intersecting form.
Sadly i can't give you a very in depth explanation it come to down understanding construction method and grind and perspective theory that are often badly documented because it somewhat very case specific.What matter is understanding the rule so that once a specific scenario arrive you can use those fundamental to overcome the perspective challenge.
Also note if you wonder why there many set of line those are use to establish proportion (generally 6 feet) between 2 line.Understanding how to measure in perspective become even more important when you understand you can accurately refer back to the height of a door anywhere in a scene if you know how to as your ''unit'' of porportion since most scene will be empty until you add character so it good to have a door somewhere early in the process to keep track of propotion inside the scene.
