How would you model a building from a blueprint?

Hi!
I'm still a complete noob at Houdini. After watching many tutorials primarily on modeling, I wanted to have a shot at modeling some specific building.



I have a blueprint and a lot of reference images - in fact I live right next to it so I'm able to checkout all the details but well,
I don't even know how to start with the basic shape.

Here's some approaches I was thinking about:

1: Use a line node for the length, mirror it and control it via a parameter from a null node. Do the same for the width, reverse and resample so the order of the points is correct
--> Somehow extrude it to be able to control the buildings height

This doesn't work as expected because using this approach, the building will be 'open' on the bottom. No idea how to fix that/to have more control over this

2: Use a Box as base geometry and work with bools or other nodes to get the shape that I want. Merge those things and work from there

3: Use an add node to generate points, use copy to points node and use line as input then basically do the same thing as in way 1

4: Use the given image and project it to a reference image plane and draw the curves by hand
--> I tried that and got some Ok results but it felt wrong


I hope this makes sense to anyone and that someone can point me in the right direction

Many ways to model in Houdini, don't take my example as the best.

Polyextrude does have option to output front and back so you can have a closed object.

Mostly to go by your blueprint I use an attribute from map and a grid as the same resolution of your blueprint file.

Hey BabaJ,

thanks so much for your reply and the attached file! I will have to check this out in more detail when I find some time but this looks really interesting so far. I'm sure I'll learn a lot from this

Cheers!
