Hello!
After some downsizing, I currently have a rough draft.
Building project:
9.5 x 10 meters (31 x 33 feet) without dormer/bay window
Basement, ground floor, and upper floor
Low-pitched gable roof, approx. 25°
High knee wall (maybe 2 meters (6.5 feet)?) to fully utilize the upper floor space
Targeting KfW 70 standard. Still unsure about heating—no gas connection available. Possibly an air-to-water heat pump?
Underfloor heating on ground and upper floors
About the building site:
Regional factor 0.929
Soil class 3-5, no groundwater up to 4 meters (13 feet) depth during drilling
New development area with established drainage system
Level ground, no slope. Slight downward slope starting from the street at the property
Allowable fill up to 1 meter (3.3 feet) on site, using excavation from foundation pit
2 carports (paving to be done as a DIY job)
Standard equipment.
Sanitary installations, flooring, interior doors, and possibly electrical work may be done largely as DIY. (I can’t really estimate how much that will save.)
Is it possible to roughly estimate the construction costs here?
What is the difference in cost and usage between a living basement and a utility basement?
(The basement floor plan does not exist yet. Planned rooms: technical room, storage, fitness, and a small workshop.)
What could extras like a long, narrow window between the kitchen countertop and wall cabinets cost? Or a large floor-to-ceiling window in the dining area (approx. 2 x 2 meters (6.5 x 6.5 feet))?
If I can provide any additional information to help with an estimate, just let me know!
The plans are only rough drafts, the window arrangement doesn’t make much sense at this stage!
Best regards,

When I enter the front door on the ground floor, I am in the hallway of unit WE1. WE1 and WE2 must be separate, so this would only work with an external staircase. Having 12.5% of the living area as window area in the basement is already very complex.
This is not an option for us, as we do not want other people in the house. That is actually one of the main reasons why we are building in the first place. When we are older, an external staircase to the attic might be an option, so that we can live on the ground floor.

I’ve decided to revisit an earlier design idea. This results in the master bedroom and bathroom being somewhat narrow and elongated. However, the advantage is a tidier hallway, the main entrance facing east, and the basement stairs are no longer awkwardly located in the utility room. The kitchen and living room have also gained a few centimeters (inches). One of the children’s bedrooms is now 2 m² (22 sq ft) smaller than the other.
Hey, I also happily grew up in a 12m² (130 sq ft) room 😀 (in a 280m² (3,000 sq ft) family house :p)
No, I don’t like that either… but I’m not managing to do it better at the moment.
My current living room is 3.44 meters (11.3 ft), which I actually liked. I guess I need to visit some more show homes. What would be considered "normal"? 4 meters (13.1 ft)?
