Hello dear community,
we are a family of five (2 adults, 3 children) currently planning to build a house. It is quite challenging to find a floor plan with 4 bedrooms plus an office/guest room while keeping the overall size affordable. We have already tested several layouts and would appreciate your feedback and comments. Our current plan is a compromise between construction costs and size. So our main focus is to get the most out of the available space. Of course, having more space would be better, but unfortunately, we are limited to about 160 square meters (1,722 square feet). We would like to use this floor plan to obtain comparable offers from home builders.
Thank you in advance!
Development Plan / Restrictions
Plot size: 550 square meters (5,920 square feet)
Building envelope: 12 m x 20 m (39 feet x 66 feet)
Slope: none
Site coverage ratio: 0.2
Floor area ratio: 0.4
Number of floors: 2
Roof type: hip roof
Architectural style: classic city villa
No formal development plan, §34
Owners’ Requirements
Style, roof type, building type: city villa with hip roof, 2 floors without basement
Space requirements ground floor, upper floor: approx. 150 square meters (1,615 square feet) (2 adults, 3 children)
Office: home office with 2 workstations
Guest stays per year: mainly grandparents, 2-3 times
Open or closed architecture: open
Conservative or modern design: modern, open kitchen
Number of dining seats: 8
Fireplace: no
Additional requirements:
House Design
Origin of the plans: self-designed based on several examples and inspirations from the internet. The windows are still placeholders.
We are unsure about the bay window. We have planned it to gain some extra space for the dining table, especially when guests come, as we can easily have 10 people. Additionally, it helps to fit in the 3rd children’s bedroom better. The question is how the cost of a bay window compares to simply increasing the overall floor area. Maybe someone here has experience with this. Also, if other arrangements might exist that use the space more efficiently.
Budget limit for the house, including fixtures: 550,000 euros (approx. $) (including photovoltaic system and ready to move in)
Preferred heating system: heat pump

I’ll keep it brief:
Get professional help; the design has many flaws. You’ll only receive comparable quotes from home builders if you involve a specialist (aka an architect). Otherwise, you’ll be comparing apples to Nutella and Hollandaise sauce.
(...) Thank you for the advice!
We haven’t decided yet on a construction method (solid masonry or prefabricated house). Would designs from an architect be independent of the construction type? Or should this be planned from the start?

As I mentioned recently in https://www.hausbau-forum.de/threads/grundriss-3-kinderzimmer-einfamilienhaus-potenziale.46428/#post-646707, I believe we have suitable floor plans for families with three children here with @Tolentino
https://www.hausbau-forum.de/threads/lage-stadtvilla-oder-einfamilienhaus-auf-500-m2-grundstueck-rechteck.33505/
and with @Zaba12 https://www.hausbau-forum.de/threads/grundriss-fuer-11m-x-8-25m-ok.24781/ (in the example by @Tolentino, the plot situation with a rear neighbor is similar. It also clearly shows that the “bay window” can be avoided if the staircase is designed more compactly). Thanks for the links, we’ll take a look.

Much of what @SoL mentioned has already been covered.
I wonder what is fixed and required here, and what is wishful thinking.
With many rooms, I always recommend a gable roof house for attic usage. There is no development plan, so we have freedom in our planning. We simply prefer a hip roof. But I can also understand that a gable roof offers more usable space.

There is no local development plan, so we are free in our planning.However, that is somewhat misleading. Is there a parking space ordinance from the municipality? Please show us an aerial photo of the surroundings to better evaluate the 34er.
34 does not mean building however you want.
You need storage space. A fleet of vehicles for 3 children. Toys, clothes passed down, seasonal items.
I find the utility room for technical equipment, storage, and laundry far too small. It’s basically a shoebox with two functions.
Bay windows are not much cheaper than the house when enlarging the entire bay depth.

But that is also a misconception. Is there a local regulation regarding parking spaces? Please show us an aerial photo of the surroundings to better assess the property at number 34. Here is an aerial photo. The plot is marked in red. You can still see the old buildings and the trees, which have since been removed.
After consulting with the municipality, there are actually no further requirements. Except, of course, §34: "Construction is permitted if it fits with the type and extent of existing buildings, the building style, and the built-up area of surrounding properties."

I find the utility room for technical equipment, storage, and laundry far too small. That’s already a shoebox serving two functions.
Bay windows are not much cheaper than the house itself to expand the full depth of the bay. I agree with you. We would like to design this room larger as well, but then the footprint also becomes bigger.
I now understand that it is probably more sensible to plan the house slightly larger instead of adding an extra bay window. Maybe then the utility room can also be planned bigger.

And please don’t come with your own amateur plan, but rather with a list of what is important to you.
They will then create appropriate plans for you that take your wishes into account, along with many of the points mentioned here.
