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.

I shifted the T*W slightly, which saves a lot of wiring.

I would mirror the storage room so that the window shifts to the right as per the plan. This way, it is also positioned more centrally at the bottom in the utility room. Aesthetic considerations take priority over performance optimization.

Are you sure? I had it like that at first. I didn’t like the two windows of the bathroom and storage being so close together. That should be the architect’s decision.

If the original poster doesn’t follow your suggestion, then the washing machine, dryer, and sink should be exactly in the opposite corner.

"I like your suggestion much better."

If the wall and ceiling panels go up, I think there’s no need for a window in the technical room at all.

If you keep the windows as the architect planned, it works. But then a frosted window should be installed in the ground floor bathroom.

Hi everyone,

thank you for the new responses. Although I mentioned that we have roughly completed the floor plan design, feedback and criticism are still very welcome. Also, thanks for the effort in redrawing.

I still have to question this mouse-tunnel entrance layout. It’s such a terrible space eater, and you still feel constantly cramped.

This falls into the category of things we tried differently (including entrances from the east/lower side of the plan or centrally from the north/right side of the plan), but we have now deliberately decided to keep the layout as shown. We do not want a direct sightline from the entrance through the entire hallway and find this arrangement appealing, even though it takes up space.

Please free yourselves from the obligation that the garage must align at the back with the house—I see no reason for it.

The corridor within the building boundaries is only about 14m (46 feet) wide in the north. For a house 12.5m (41 feet) wide (+ possibly roof overhangs, it is still being clarified whether these are allowed to extend beyond the boundary), the carport/storage room could only be shifted slightly. We tried this for a while but found shifting it for just about a meter (3 feet) to be awkward. The zoning plan also explicitly excludes accessory structures like carports, storage rooms, or garden sheds from being located outside the building boundaries.

Extra shower

This has already been debated extensively in the thread; we have explicitly decided not to have it on the ground floor.

trying to use every centimeter for the tight dining area.

I have to disagree here. The dining area, as shown on the plan (this time with dimensions), is 4.10 m (13.5 feet) wide, which we already consider almost too large. The drawn dining table and especially the chairs (more like armchairs) are actually huge, so the scale might be misleading, but there is plenty of space—even considering the main passage through the living/kitchen/dining area.

Upstairs, the bathroom is a disaster, but you’ve already acknowledged that yourselves.

This is indeed currently our favorite layout, except for some minor optimizations. I think we will keep the positioning of the fixtures as shown. We experimented with different layouts for this room and consulted a bathroom studio, but they didn't come up with a better solution, neither for an L-shaped nor a more elongated bathroom. Disclaimer: We have another appointment scheduled with a different bathroom studio soon, so maybe they will have better ideas.

I also want to point out the nearly unusable storage room (if no one else has). It offers no real space to store anything.

Yes, we are aware of that, and it’s one of the areas where we will still move a wall. I think a depth of 40 cm (16 inches), possibly on both sides, will serve the purpose; we don’t actually need 60 cm (24 inches) there.

I tidied up the bathroom a bit.

This looked quite a lot like one of our first drafts, which we quickly discarded. The main issue is the walk-in shower, which in this position:
  • is open directly to the door and therefore shorter than desired, but more importantly, will lead to moisture at the door and eventually cause it to swell.
  • receives no natural light, so you always have to shower with the light on.

Washer and dryer in the storage room. That’s where the laundry is generated. This relaxes the situation in the utility room, which has become somewhat smaller. The bathroom is only 10 cm (4 inches) smaller.

True, that’s where the laundry accumulates. But then you always have to carry it damp downstairs to hang it outside (which we do a lot even in winter). Also, we plan to spend more time downstairs anyway, so the routes for hanging/collecting laundry are shorter. Therefore, the washer and dryer will remain on the ground floor.

Just as a heads-up: I might not be able to respond extensively in the next few days if many more posts come in. I will try to catch up later 🙂
