loxorHello everyone,
Since this is our first post, we would like to briefly introduce ourselves. We are a young couple, both 29 years old, and have been living together in rental apartments for 8 years. Now that we have settled down professionally, we have been thinking about buying a plot of land and building a house, and we have warmed up to the idea.
We have found a nice plot, but unfortunately it is tied to a specific developer. Since it is very difficult to find plots, we still requested an offer. We set a budget limit of 450,000 euros (including additional costs). However, the offer was 407,000 euros without additional costs. The scope of work is also not entirely satisfactory, so additional costs of around 20,000 euros would arise. Including extra costs and landscaping (I hope I did not forget anything and calculated generously), we would end up at 520,000 euros, which is unfortunately well above our budget.
We are somewhat satisfied with the design, but we will have to make compromises to reduce costs. Our requirements for square meters and features are listed below.
We look forward to your opinions and wish you a pleasant weekend.
Best regards from East Westphalia

House design
Planned by: developer / architect
What do you like most? Garage, living/dining area, and large utility room
What do you dislike? Children’s room upstairs is a bit small, bathroom too large, sauna not necessary. Staircase is directly in the entrance area.
Price estimate according to architect/planner: 300,000 euros + land
Personal price limit for the house, including features: about 250,000 euros
Preferred heating system: gas
If you have to give up something, which details / additions would you forego?
- Can give up: walk-in closet, garage but instead a double carport
- Cannot give up: large living-dining room, guest toilet with shower, work/guest room
Why is the design as it is now? For example: Standard design from the planner. We would like to move the bay window to the north side.
What is the most important/basic question about the floor plan in 130 characters or less?
Our vision was:
- Single-family house
- Upper floor: 3 bedrooms (15–18 m² / 161–194 ft²) + bathroom (approx. 10 m² / 108 ft²), total 55–64 m² (592–689 ft²)
- Ground floor: small shower bath (4 m² / 43 ft²), utility room (approx. 10 m² / 108 ft²), living-dining area (approx. 30 m² / 323 ft²), kitchen (approx. 10 m² / 108 ft²), office/guest room (8 m² / 86 ft²) = 62 m² (667 ft²)
Overall 117–126 m² (1,259–1,356 ft²) excluding hallway / vestibule etc., we are unsure how much to include for those.
- Double garage with access to utility room (would be a dream but not necessary)
Our total budget with all additional costs was 450,000 euros. The land costs 130,000 euros. The land has a developer tie-in.
We look forward to your opinions.

Have a great weekend as well.
Personally, I don’t think the design is that bad. In fact, it’s quite good. You could enlarge the second children’s room without extra cost by reducing the size of the dressing room or bedroom.
Have you considered where you could save the €70,000 (about $77,000)? The heating system will probably be gas, so that’s likely not an area to cut costs. €70,000 (about $77,000) is a significant amount that you can’t easily save even with your own labor.
It doesn’t really make sense to discuss floor plans if you don’t have a solution for the missing money. Do you have one? Even your planner/architect is designing based on a building specification that is €50,000 (about $55,000) over budget!

I have a similar floor plan in mind. There is also something like that available from a detached house provider. Well-copied is half won: search for "Neo 311 with bay window on BP in BW."
Of course, this is not meant as a recommendation for a detached house... but it always works as inspiration for planning the floor plan.
And since you’re also asking about prices: as a solid masonry house made of sand-lime brick with external thermal insulation composite system (ETICS) starting at 287,000 plus additional construction costs plus price increase from April in southern Germany. So, the architect’s estimate doesn’t seem too far off.

The easiest way to save money is to leave out the dormer. That will probably save roughly around 10,000, roughly estimated... but do you really want that – or why did you want it on the north side in the first place? It doesn’t make any sense at all with the staircase, does it...?
