Bungalow floor plan for 3 persons, 130 sqm, please opinions...

Thank you, I agree. I also think that you are not just building for the children and that the added value also comes from the garden, etc.

I also didn't have a huge children's room as a child and 12sqm is standard even in apartments. I really don't see the big problem there.

The floor plan is an absolute disaster!

I’ve attached a picture of various houses that inspired us.

I think you have obviously already put quite some thought into it

I have now cleared the floor plan. Living room, kitchen and terrace are the highest priority, and maybe someone has a good idea how to sensibly build the bedrooms around them to save hallway space.

One therefore unfortunately has to "sacrifice" the "partial success" in order to clear the way for the recovery of the whole. Structures that were really good will automatically re-form.

This is a clear decision. The smaller you build, the more thought you have to put into it to make it really good. We have a motorhome and manage very well with little space. From the motorhome experience, we incorporated a few wishes into the architecture of our house. My question about whether it should stay that way was indeed serious, even if a "Haha" was added.

I understand the task for an architect as follows: A practical "space miracle" should be created for a family of three with small private rooms, a technical/utility room, a separate living room, a small office, and a room with kitchen and dining table where the main family life takes place. Since the residents imagine their life as a connection between inside and outside, special focus should be placed on the connection of the "living space." Entrance and traffic areas should be minimized and kept practical (cloakroom, guest toilet). The residents do not value representativeness or hosting guests. Since the children's room remains small, it is desirable for the child to have their own private outdoor area with friends as they grow older. An exit to the garden and space for a later garden design that meets the requirements would be desirable. The residents would like to include the beautiful view to the west in their life. The shape and placement of the house on the property adapt to the requirements; there are no specifications here and freedom for creativity. Likewise, there are no specifications for wall construction and building services. Parking spaces near the house entrance are preferred. The residents like to engage with ideas from the tiny house sector or creative suggestions that do not conform to general standards, as long as they are not extraordinarily costly. The residents like to spend their time with ..., ... and .... The budget for the construction including xxx and yyy is currently €zzzt.

Bet that an architect can do this better than us here? Bet that with this planning freedom, architects are interested not only in the budget but also in the task, which finally gives them creative freedom again? Bet that a creative, inexpensive solution for a likeable family is a reference for an architect that they would like to use? Bet that an interested architect is willing to plan this for a flat fee?

What comes from a freshly thinking architect (m/f/d) will exceed expectations (and the budget too, so specify 20% smaller than what is pain-free).

For example, the dimensioning of the property and budget expectations.
It’s no use if someone plans a low-budget house for you here, and you could and want to spend much more.
Likewise the other way around: details in the floor plan are expensive – what’s the point of suggesting mega sightlines that take up several square meters and you can’t afford them?!

That’s already a good approach: the child has an adequate room on the ground floor for a few years, the office goes into the attic (flat gable roof), and when the child can and wants to sleep alone, the rooms are switched. An average staircase is enough, e.g. a steel stringer, which is quite modern, timeless, and affordable. That way you have good use of the attic, which is there anyway. This allows you to minimize downstairs somewhat and balance financially – and you have the spatial separation.
Later, upstairs you have a nice room for the next hobbies (yoga, guests, etc.)
What about an architect?
I’ll look at home what I still have saved on the computer – if the property width is known…
It’s just that right now we have summer weather, so I avoid the PC – but sketching while lying down works ;)

Large rooms have to be affordable. Small children's rooms are okay with a small floor area. Only with 200+ sqm, a parent's room of 50 sqm and a large gallery are 12 sqm children's rooms too small. Here the office is too small, child and parents swap, kitchen too dark
