House Design
Who designed the plan: Planner (Architect?) of the general contractor (GC)
What do you particularly like and why?
  • Straight staircase
  • Covered entrance and terrace
  • Spacious enough for our needs

What do you dislike and why?
  • Ground floor WC probably too small
  • Pantry doesn’t make much sense (maybe omit)
  • Layout of the bathroom upstairs (we already have alternative ideas)
  • Unsure if there is enough light in the living/dining area
  • Slightly too big / bulky
  • A bit too expensive

Price estimate according to architect/planner: 565,000 EUR
Personal price limit for the house, including fittings: 730,000 EUR (including garden, carport, photovoltaics, kitchen, additional costs)
Preferred heating technology: Heat pump is basically a must (no gas connection)

If you have to give up, which details / extras
  • Can be skipped: open atrium, pantry, if necessary the type of covering on entrance and terrace (set back under the upper floor)
  • Cannot be skipped: Storage space

Why did the design turn out the way it did?
Three-hour meeting with the architect at the general contractor, starting from a similar model house (this was a 1.5-story house with a gable roof), several iterations on tracing paper, then a week later the digital design was received.

Which wishes were implemented by the architect? Covered entrance and terrace set back under the upper floor, bedroom with dressing room, 2 studies (1 ground floor, 1 upper floor).

What do you think makes the design good or bad? Overall we quite like the whole package.

I’m looking forward to your opinions and am curious about what you think. If we still like the design in January, we will probably proceed with further planning with the general contractor.
Ground floor plan including kitchen, dining, living, workspace, entrance hall, WC and carport

Upper floor plan with bedroom, dressing room, children's room, guest room, bathroom, hallway

Section through two-story house with roof structure, underfloor heating, windows and doors

Two-story brick house with gable roof; four facades (east, south, north, west)

Site plan of a plot: red boundary, green area, blue borderlines, scale 0–20 m (0–65 ft), neighboring buildings

Where is the second parking space located, or do you count tandem parking spaces?

We are still undecided whether two spaces in a row (so one essentially between the driveway and the carport) are sufficient. Is that what you mean by “tandem”?

Otherwise, we have paved an additional uncovered parking space on the west side in front of the utility room.

I don’t think the development plan specifies that both parking spaces have to be independently accessible. Is that usually a requirement?

Answer part 2 (note to myself: Google first, then write):

I have now understood what trapped parking spaces are. Thanks for the hint, I had never heard of this before.

Neither the zoning plan nor the Lower Saxony building code explicitly mention this topic, so for now I don’t see an issue. I will ask the architect again at the next meeting; I believe they are quite familiar with the regulations.

The living room wastes a lot of space, which basically can only serve as a dance floor. But that’s due to the very large upper floor. A 26m² (280 sq ft) bedroom and dressing area, 19m² (205 sq ft) children’s room, plus a guest room—you really have to need all of that.

Do you have guests often enough that you can’t fold out the couch in the living room or accommodate them in the office?

My mother is very happy with the couch in the living room and stays with us around 30 to 35 days a year.

I have to smile about the exterior work.
25,000 (25k) will probably be needed for the entire exterior, including garden, hedge, tool shed, paving, etc.—that’s just for materials and tools; I’ll do the work myself.
For an attractive fence alone (no welded wire mesh or precast concrete elements), you can easily spend 25,000 to 30,000.
If we’re really talking about a completely finished garden, driveway, etc., done by a professional company—not "Handwerk 24/7 Poznan"—then a good standard will easily cost 60,000 to 70,000.

Regarding additional construction costs, it depends on what the general contractor states in the contract about the foundation.
If it says something like “30cm (12 inches) gravel base included, everything else extra,” then you can expect several tens of thousands more costs.
Utility connections won’t come in under 10,000 EUR either.

Oh, I see. For some, this might seem trivial... but almost 6 meters (20 feet) from the couch to the TV.
Even a 70-inch screen looks tiny at that distance.

A trapped parking space definitely deserves its own consideration. If two cars are regularly in use, trapped parking spaces can often be very impractical.

Regarding the floor plan... hmm.
  • Air space... that small one near the entrance... what is it supposed to be useful for? That would be an immediate elimination point.
  • Floor-to-ceiling windows throughout the upper floor... with the planned furnishings, you can clearly see desks placed in front of the windows. This will also frequently expose wiring and cables. That would be a deal-breaker for me as well.
  • The staircase is designed quite narrowly, with the upper floor overhanging the first two to three steps. A close look at the section is needed to check whether tall people might risk bumping their heads when coming down.
  • Entrance slalom past the WC into the office. The main wardrobe is also there, and this is with two small children.
  • Kitchen / dining... if arranged as planned, terrace access from this area is very impractical because the table is directly in the way.
  • Master bedroom, unfortunately there are no dimensions given. I find bed placement with the headboard right next to the external doorway very critical. The hallway to the left of the bed also looks somewhat narrow.
  • Children’s rooms are quite large.
  • Bathroom with a floor-to-ceiling window facing the street—obviously, this will require privacy screening. The layout leaves too little space between the sink and the bathtub. However, dimensions are missing again for a more detailed assessment.

So, I think it needs to be revised.
