Hello everyone. I would like to present our upcoming project below. It is intended to inspire, provoke discussion, and serve as documentation.

Size of the plot: approx. 2,700 sqm, of which approx. 1,200 sqm is forest area (marked in green). Demolition of the current building: house number 33.

Plot is located in a dead-end street (NRW). There is no development plan. Approximately 2m height difference in the planned building area. Slope descending towards east/south.

Maximum heights/limits: ridge height of the neighbor approx. 9m.

We have given the architect largely free rein (exclusions: flat roof, hipped/pyramid roof or townhouse/Bauhaus style).

2 adults (31 + 27), no children yet. Planned maximum living area of 160-170 sqm.

Ground floor: spacious living/dining area. Large kitchen. Small shower/WC on the ground floor, small storage/mudroom.

Upper floor: bedroom, 2 children’s rooms, separate dressing room, 1 bathroom. (Guest room in the basement or upper floor)

Basement: utility/technical room, fitness, office/guest room, small WC (as there is direct access to the garden).

Only a small office necessary, as no home office work required.
Balcony, roof terrace: unnecessary, because of the garden.
Garage, carport: double garage + 2 parking spaces.
Small outdoor sauna planned sometime later.

House design (In the 3D plan I removed two walls on the south side on the ground floor so that you can look inside the house. Window planning is not yet included in the design.)

Ground floor: We personally like the layout 100%.

Upper floor: We find it almost optimal. Small open space is nice. Children’s rooms are next to each other. Parents somewhat separated. The upper floor also serves as shading for the ground floor in the terrace area. (Balcony unnecessary and will be removed)

What do we not like? Why?
The floor plan is currently a bit too large. Planned were 160-170 sqm living area (even this area we find almost too large, especially if we do not have kids). The current floor plan has approx. 190 sqm living area + basement (approx. 6m x 13m + 6.5m x 6.5m living area).

Questionable to what extent the size of the floor plan can be reduced without restricting the sense of space too much. The living area and possibly the stairwell could be designed somewhat smaller. Circulation area is relatively high. Arrangement on the upper floor could be optimized, e.g. bedroom rather towards the north. Questionable whether a second bathroom on the upper floor is necessary.
Placement of the building on the plot still needs to be discussed. (Garage would currently be planned at the neighbor’s boundary)

Price estimate according to architect/planner: starting at approx. €2,700/m² (without interior fittings)
Personal price limit for the house, including exterior area, architect, additional costs, interior fittings: approx. €700,000, but with approx. €100,000 buffer available. (Plot already paid for). Timber frame construction was planned, but due to material price/delivery time developments for wood, massive construction is also being considered again.

Preferred heating technology: heat pump / additionally photovoltaic system for electricity (without storage)

If you have to do without, which details/extensions
Living area and terrace could be smaller. Garage could be smaller. It does not necessarily have to be an L-shaped floor plan. Photovoltaic system could come later. Partial basement would suffice (makes less sense due to the slope and would probably hardly lead to financial savings). Open space not absolutely necessary.

-You cannot do without: separation of kitchen/dining area from living area. Double garage. Separate dressing room.

Why is the design the way it is now?
We gave a roughly formulated requirements profile to our architect. No specific requirements regarding floor plan/room sizes were made.

What is the most important/basic question about the floor plan summarized in 130 characters?
Price limit and rough preliminary calculation by architects realistic? How could the living area be slightly reduced? How strong would the acoustics spread via the open space to the upper floor? Is there anything against the planned terrace? (Basement ceiling = terrace floor practical?)

We are open to general criticism and suggestions for improvement :) We will gladly report on further progress in the coming weeks.

Why are you planning 3 levels?

As I see it, there is no garden access from the living areas?
You could do well with 2 levels and a roof. Then there would be some extras within the budget too. The plot allows for that, right?
Isn't one level missing in the presentation?

And yes: don't be confused if a user now talks here about questionable words like "suspects," just because one/I question 3 levels.

There would probably be additional steps leading to the garden. The terrace would thus be somewhat separated from the garden. That has advantages and disadvantages. The lowest level is the basement. However, there is no floor plan draft for it yet. The basement partly protrudes from the slope and offers direct access to the garden.

The attic would be unfinished and open.

It's a nice plot - really idyllic :) I'll look up the last thread about the slope issue for you, when there is no direct access to the all-purpose rooms. https://www.hausbau-forum.de/threads/efh-sued-hang-grundriss-ca-160m-mit-keller-und-garage.39390/ Please read. The same criticism applies to this house. There are many discussions here about the hillside location.

Thank you very much for that. Access to the all-purpose rooms would – as already written above – at least be possible via a few stairs. Maybe part of the garden will also be slightly raised. But ultimately, due to the elevation, the terrace would of course be somewhat separated from the garden. Which I personally don’t find so bad at all.
