Planning tutorial: Which house planner software should I use?

After my related contribution as a reply in an existing thread seems to be too "hidden" to have been seen, I am now trying again in a separate thread:

I intend to create a planning tutorial for those floor plan do-it-yourselfers who would otherwise hopelessly get entangled in Tetris. However, I do not want to do this in the form of a video. Instead, I want to plan a small selection of sample houses so that these plans can be adapted by users themselves – directly in the file as a craft sheet. In other words, as if one were starting a project in planning software oneself. Only in such a way that you are not sitting cluelessly in front of the blank screen, but the starting material is already there as a cake base / kit.

The user should not have to "trace" a template design first but receive it pre-processed in an editable form. In doing so, I want to, for example, thoroughly examine variants with their respective consequences (changing the knee wall height, inserting a captain’s gable, adding a bay window, etc.). For example, what a Flair 110/113 would look like as a substitutional villa or as a bungalow.

So a whole house as a template. You should be able to download it and keep working on it. For this, I would preferably like an offline-usable house planner software that is widely spread and/or whose file formats can be opened and edited by other house planners. If necessary, an online house planner software would also be acceptable if you can invite an unlimited number of other users to "share" the project with (and who naturally must be able to work in it without permanently altering it for other users).

Of course, I cannot create such templates for multiple programs in the "voluntary framework," but only for one with the widest possible distribution. Which one it would be does not matter to me, since I would have to familiarize myself with each first.

Which house planner software do you recommend to me in this regard?

Even though it certainly has many shortcomings, I would suggest Sweet Home 3D due to its widespread use. This covers everyone, including Mac and Linux.

Even though it certainly has many shortcomings, I would suggest Sweethome 3D due to its widespread use. This way, everyone including Mac and Linux users are covered.

That would also be my suggestion. In my opinion, it also offers comparatively good options for outdoor design.

For interior design only (including decoration, etc.), I find HomeByMe better.

I find HomeByMe the best. It helped me a lot in finding the perfect floor plan. The ability to walk through it in 3D helped me better assess the proportions. And the fact that it can be operated entirely from the browser and is therefore accessible from anywhere to show it to friends and family is great.

Great idea! Three years ago I looked for planning tools and didn’t find a single free or affordable program that I liked - I couldn’t properly represent our house shape in any of the programs nor import the plot of land, so it was a dead end for me.

Distribution is an issue worth considering.

What I find important:
Simple operation, clear 2D representation, integration of building services, input of measurements not only with the mouse, function to save and share,
What I find less important:
Selection of furniture, objects, and colors (that annoyed me because nothing fit),

... but with that, you are already in the semi-professional area ;).

... your attempt is honorable .. I just fear, from experience in the other forum where we tried it with kitchen layouts, that a) it requires enormous maintenance effort and b) it is still somehow a niche.

What would be important in such a program is also the easy modification of the given floor plan, rotating, mirroring, etc. and a good stair editor ;)
