Floor plan design with existing house

Hello Ronny,
if your entrance side is the south side and at the same time the street side, I wonder why you use a kind of standard variant when you make considerations about your future floor plan? Do you want to buy a typical house and possibly adapt the floor plan to fit your planned garage? Or do you want to aim for a freely designed house?
But actually it doesn’t matter, since houses can also be rotated and mirrored.
Now, what I’m getting at: you are sacrificing the south and west sides and planning an overpriced roof terrace, although you have a 2000 sqm plot. No one will use that terrace, but your garage will get wet at some point.
Since we don’t know the dimensions and the development plan of the plot, not much can be said, nevertheless I can say that a much better floor plan would be possible in "your" building area if you would stop planning your garage in the prime spot (hobby and workshop can still be combined with a garage, just not like that).
Your plan looks to me like a farmyard that has been extended and patched on again and again for over 50 years, which no longer serves its purpose.
I think if you draw on millimeter paper and can quickly erase something again, you will get further than with freeware. Send us the scanned plan of your plot plan sometime...
Regards Yvonne

Yes, I can do the site plan tomorrow.
It wasn’t a standard house, I planned it alone, nothing was predetermined.

How could the garage get wet? Why is that? Are there no proper seals there?

Best regards, Ronny

That was not a standard house, I planned it all by myself, nothing was predetermined.

How could the garage get wet? Why is that? Aren't there any proper sealings?

Yes, you can tell that no professional was involved.
But judging by the external dimensions, you want a house like that and to attach your garage to it.

A flat roof, especially one that is walkable, is always a troublesome issue that requires investing money...

Hi,

Well, anyone who knows the program probably also knows that it’s not that great and that there are limits for a freeware program

apart from the fact that I find the floor plan quite poor myself, honestly, you should first practice using the program or draw by hand. As it is, it’s really rubbish...... Then furnish all the rooms and work with the correct symbols. It’s hard to judge anything when you’re supposed to imagine away so many things. Or imagine it differently.

So first draw a proper floor plan and post it here again.

Regards

Well, anyone who knows the program surely also knows that it's not that great and that there are limits to freeware programs somewhere

But it can be better! Most components can be entered flexibly, so windows and doors can have individual widths.

The bathroom on the ground floor should only have a toilet and a washbasin; it can even be smaller, I've seen that many times, especially when doing service work as a heating and sanitary technician.

Of course it can be smaller. But not in the way you planned it. Then the door would have to open outwards.
Behind the door you won't have space for a washbasin or toilet, nor directly in front of it. Otherwise, the door wouldn't open. Only the wall on the right remains. But you can't fit both there either.
Additionally, you would have to add 15 cm for the installation wall. Then it gets tight!

hello, so here is an aerial photo of the property. The house is still standing as it is, the extension on the front right should be removed and then rebuilt as shown in the plan above. The shed on the left is also still there and has been modernized as well.

best regards Ronny
