House Design
Who created the plan: architect of the general contractor
What do you particularly like? Why? – Entrance located in the basement because otherwise a steep entrance staircase around the house would be necessary; home office with window in the basement; terrace on the garage; upper floor with separate bathroom for children.
What do you dislike? We don’t like the orientation. We would prefer the gable sides to face north/south (mainly for the view; as currently planned, from the upper floor the southern or city view is only visible through roof windows). On the ground floor, a laundry room is planned facing the sunny south, which we find less practical. With the office in the basement, the usable living area is now 212 sqm (2,280 sq ft). We think we can manage well with 180 sqm (1,940 sq ft) overall. Perhaps the children’s rooms are each 2 sqm (22 sq ft) too small. Also, we are not comfortable with the many small, irregularly arranged windows.
Price estimate according to architect/planner: approx. 550,000 EUR turnkey plus 20,000 EUR landscaping plus 10,000 EUR landscaping = 580,000 EUR
Personal price limit for the house, including fittings: 550,000 EUR
Preferred heating technology: ?

If you had to give up, which details/finishings
- Utility room on the ground floor
- Cannot do without: separate bathroom for children

Why is the design like it is now? For example,
We gave some initial verbal ideas but allowed the planner considerable freedom.

What is the most important/basic question regarding the floor plan in 130 characters?

The planner sees only this orientation as sensible; however, we do not like it. How could the ground floor be better designed despite the staircase at the south side, which takes space from more practical rooms (possibly the kitchen)? Any ideas on the exterior design?

Basement floor with double garage, technical room, cellar, office, utility room and entrance.


Ground floor plan VE 01: living and dining area, kitchen, WC, hallway, terrace


Upper floor plan: bedroom, two children’s rooms, bathroom, hallway, stairwell, orientation.


South elevation: house with garage, terrace and tree; north elevation with windows and people.


Architectural drawing: house on slope with terrace, west and east views.


Street with paved walkway, grassy embankment and row of trees under blue sky.

Are the garage and earthworks included in the construction costs? —> Yes, at least according to the rough estimate.

Somehow, I don’t like the floor plan. I just don’t know if I’m being objective. —> I can generally live with the upper floor. I’m also unsure about the ground floor.

Do you need the basement? The utility room is duplicated. Why isn’t the wardrobe downstairs? —> We also consider the utility room on the ground floor unnecessary. The wardrobe would make more sense in the basement, as it takes up space on the ground floor. The basement is basically essential due to the sloping site.

Is there a development plan with a designated building area?
Is it possible to extend the garage slightly beyond the main house to create a larger terrace on the garage roof?
Both children's rooms should face the street → the sunny side, and they have a nice view...
I would place the main entrance and the adjacent staircase on the east side, allowing more living space on the sunny south side.

It is clear that the excavation work is included, as it would not cost just 2,000€.

Does the offer explicitly include removal and disposal? Because those are usually not included.

Having the terrace on the south side definitely makes sense. On one hand, you can use the garage roof, and on the other hand, only up to ten cars pass by there daily. It’s just a quiet residential street.
But you have zero connection to your garden! When you step outside, you want to see the flowers you’ve cared for all year or watch the children playing. So I open my house towards the garden. I’m not trying to strongly discourage you from using the garage terrace, but “beginners” often tend to try to use something in a particularly “efficient” way and completely forget to adapt their house to their way of life.

That’s true. It caused a five-figure problem for some friends of ours.

@haydee The entrance is not dark because it is illuminated by the window on the ground floor. It is narrow, you are right about that.
