House design

What do you particularly like? Why?
What do you dislike? Why?

Personal price limit for the house, including fittings: 600,000 €
Preferred heating technology: underfloor heating
If you have to make compromises, which details / extensions
- can you do without: open to suggestions
- cannot do without:
Why is the design the way it is? For example:
Since we absolutely need the separate apartment, the design grew in size, and after 5+ drafts, this should now be the final version
A mix of many examples from various magazines...
What makes it, in your opinion, particularly good or bad?
What is the most important / fundamental question about the floor plan in 130 characters?
Can the design be slightly reduced without losing rooms?
I hope nothing is missing—otherwise, please contact me.

but not related to the development plan at all. We don’t even know that yet!
Maybe the original poster isn’t even allowed to implement their wishes. The development plan I included is just for clarification for the original poster.
But the possibilities of the development plan aren’t really that important anyway...

The OP added one in post No. 12.I missed that. Then the plot ratio will really become quite tight.But as I said, a) an architect needs to be involved and b) the budget definitely has to be increased significantly.

Anson Argyris13 Jul 2020 13:52Basically, I have to agree with you; I would like to get help from a professional, but if I have to invest several thousand euros just in the initial concept, it’s a bit discouraging. The home building company has estimated about 9,000 euros for the architect, so we wanted to do as much preliminary work as possible ourselves.
Regarding the secondary apartment with the young man, a rental agreement will be made so that I have some security, and if he moves out, I can still rent it out.

Ypsi aus NI13 Jul 2020 13:57What this granny flat will cost you (not just financially! Especially in terms of quality, as you limit your planning options for your own floor plan!) you can also give to your son as a rental subsidy for living elsewhere...
Let these arguments sink in, think it over for a few days, and then decide again whether to go with or without the granny flat.

Let the arguments settle first, think about it for a few days, and then decide again whether to go with or without the granny flat. That’s it!
