House Design
Who designed it:
- designer from a construction company
- based on the floor plan of a pitched roof house by a South German ecological prefabricated wood construction company
What do you particularly like? Why? Seating window and the staircase dividing the living-dining area, open ground floor, discreet upper floor
What do you dislike? Why? Storage space might be tight, utility room possibly too small
Price estimate according to architect/designer: not yet known
Personal budget limit for the house, including equipment: –
Preferred heating technology: air-to-water heat pump

If you had to give up, on which details/extensions?
- could you give up: KFW 55 standard, T-solution in bathroom, kitchen island, if good reasons: possibly rotate the straight staircase 180 degrees to access it from the hallway
- cannot give up: in our opinion, the design does not reflect exaggerated demands already

Why has the design ended up like it is now? For example:

What makes it particularly good or bad in your eyes? The garden is important to us. In our opinion, the rectangular footprint is better suited than a square one to get the optimum out of the plot (sun on the west terrace). The floor-to-ceiling window on the south side in the kitchen.

What is the most important / fundamental question about the floor plan, summarized in 130 characters?
The ground floor is nicely open and cozy and connects the garden and terrace with the house, while the upper floor offers enough privacy both inside and protection from outside views. We searched a long time for the optimal plot and want to use the land as the garden ideally as a retreat, with a possible swimming pond / pool later and a small vegetable garden.

Site plan of a residential block: blue building outlines, yellow streets, green circles as trees.

@ypg @11ant @pagoni2020 @motorradsilke @hampshire Do you have specific floor plans you would recommend because they avoid common mistakes? I mean, you all seem to have seen a lot and got some insight into our preferences. We’ve also moved several times and managed to adapt to every apartment. We haven’t lived in houses yet. So maybe there are some basic rules that certain floor plans follow, which we could build on. Before starting over, I’d like to get some inspiration from you...

No, I don’t have any for two-story houses because we built a bungalow. I can only share how we approached it:
1. Look at model home floor plans. There are many functional layouts, even if none are perfect.
2. Think about what I like and dislike about these plans.
3. Consider what is important to me. For us, some things were non-negotiable, like a large entrance area with enough space for at least two people to get dressed at the same time, a fireplace, a walk-in shower, toilet right near the entrance, large windows facing south toward the garden, no walk-through rooms, and everything as open as possible…
4. From this, I created a floor plan and shared it here. I received some useful tips that I then incorporated. Additionally, I discussed the plan with friends and family. I carefully considered their feedback, adopting some suggestions and discarding others because they didn’t suit us or weren’t feasible.
5. Then I adjusted walls until we were happy with the layout or found a compromise between preference and practicality. For example, I would have preferred to have the bathroom facing the back or the main entrance on the side, but that didn’t work with other requirements.
In the end, we created a home where we have felt very comfortable for 8 weeks now.

Our utility room is just under 9 square meters (97 sq ft). It fits all the technical equipment, plus a large shelf 3 meters (10 feet) long, floor to ceiling, and 60 centimeters (24 inches) deep for painting supplies and storage. The washer and dryer stand side by side with a connected workspace, and there is room to add a drying rack if absolutely necessary. I stood by the installers to make sure they only installed what was planned exactly at the designated spots. But I wouldn’t be able to fit any decorations, suitcases, or similar items in there anymore.

Am I the only one here who finds 2.13m (7 feet) for window reveals really cramped? I was already somewhat annoyed with my 2.26m (7 feet 5 inches).

Common measurement for a room height of 2.5m (8 feet 2 inches):
2.13m (7 feet) + 30cm (12 inches) roller shutter/blind box + 7cm (3 inches) lintel

Good morning, yes, I’m still here, I just wasn’t at the computer over the weekend 🙂 The Gussek Murano house already comes very close to our expectations. I’m a bit concerned about the dark interior corridor, though. Perhaps that could be improved with interior glazing towards the utility room.
I’m also trying to clarify something pointed out by @11ant, regarding how much the height differences will affect our planning.

Unlike the others, I like the straight staircase placed across the room to break up the narrow house layout (especially the narrow open living area) and to create separate zones. Especially if you don’t want to look from the sofa directly to the dining table and kitchen. However, I would definitely change the direction of the staircase so that it starts in the hallway. I also think an open staircase might not be ideal if you have children. I would use the space under the stairs for storage or a pantry.

Have generous glazing on the south side of the kitchen above the countertop.

Upstairs, I find the hallway too large, and for me, the children’s rooms belong on the south side and the parents’ room on the cooler, quieter north side. I would therefore mirror the layout there.

Definitely shift the house one meter (about 3 feet) to the left; otherwise, every postal delivery person will be leaning on your car. Then, behind the parking space or carport, add a 4-meter (about 13 feet) wide storage room for items that can also be stored in unheated conditions. If necessary, insulate it yourself and install a frost guard.

And here’s an idea of what that could look like:

Ground floor: Larger utility/technical room with a standard door, more space for a coat area, bigger kitchen, etc.

Grundriss eines Hauses: Wohnzimmer, Küche, Gastzimmer, Abstellraum, WC/DU, Haustechnik, Carport.


Upper floor: Larger children’s rooms facing south, hallway reduced to allow more wardrobe space, bathroom made more appealing. Only the separate (but space-consuming) dressing room would be removed.
