House Design
Who designed it: put together myself
What do you like most? Why?
- Direct access from the bedroom through the dressing room to the bathroom
- Cloakroom niche keeps dirty shoes outside the main passage area
- Floor-to-ceiling windows for lots of light
- Straight staircase, looks modern, easier to walk on than a spiral one and better for accessibility later (stairlift)
- Very spacious living/dining/kitchen area (though perhaps too large?)
- Pantry with everything easily accessible on open shelves
What do you dislike? Why?
- Huge waste of space in the hallways

Why did the design turn out this way?
I saw a similar layout in a townhouse that I really liked at first glance. We want a generous living feel with large window areas.
Since we are planning without a basement, an extra room upstairs was created for storage, guest room, and workshop space.
Important: the bathroom layout is not really planned yet. I have inserted my first idea there but I know it is still far from a “good idea.” For now, the focus is on the basic room layout. The windows are currently more of an idea than fully thought through.

What is the most important / fundamental question about the floor plan summarized in 130 characters?
- Do you see a way to reduce hallway space despite having a straight staircase?
- What is your overall impression of the design?

Unfortunately, my software doesn’t support creating views... The base model is the Solitaire 165, but only various designs (including extensions) are available on the website. We have also increased the height and width by 30cm (12 inches) each. The roof pitch will be 20 degrees.

The eaves sides are shown at the top and bottom of the plan. However, in our design, we raised the knee wall to 2.06m (6 ft 9 in). I probably should have mentioned that earlier, sorry.

P.S.: Attached are the original floor plans

- The living room window is positioned so there’s still enough space for a larger sofa. It also annoys me a bit that it’s not directly opposite the hallway... But I don’t want to limit my furnishing options because of that.
- The window is placed so close to the corner to create that "large glass corner." This was planned by the manufacturer, and honestly, I didn’t question it further... Would you prefer if it were separated?

- Where will the terrace be located?
I find such glass corners modern, but in the end, we would probably choose a more conventional layout and position it closer to the kitchen. But that’s a matter of personal taste. Unless this will be the terrace access, then definitely move it.

Our staircase will be open. We would also like a glazed element next to the front door, but I was more thinking about integrating it with the door itself. Or would you rather install a fixed window next to the door?

That’s also a matter of personal preference. We like glass elements beside the front entrance door, plus the effect of bringing daylight into the hallway. Whether one or two panes and how wide depends on taste and budget.

- What do you mean about the office? It is supposed to have a double casement window, and I’d prefer to open the right side first, so the desk isn’t in the way.

Then it’s all good.

Do you perhaps mean the hinge side? I don’t see any indication of that in the floor plans, and none at all in the elevations (?)

That’s probably what I mean. When I wrote it, I was just wondering if architects have a specific term for that on the floor plan.

The terrace extends from the large kitchen window around the house to the window next to the sofa. This means that all three windows will provide access to the terrace. I think people will mainly go outside through the kitchen, as you want to carry drinks and food in and out.

By the way, I told my husband about your idea, and we have now moved the window so that it is centered on the hallway—though this means losing some of the full sofa arrangement.

@haydee The slope will be filled in or a section at the top will be excavated. The details are not finalized yet, so whether it will be terraced or not is still to be decided. I have currently planned the staircase to be 4.10m x 1m (13 ft 5 in x 3 ft 3 in). At the top, there is a distance of 1.20m (4 ft) from the wall (from which unfortunately a parapet has to be deducted...), and at the bottom 1.40m (4 ft 7 in).

The width is fine. It appeared differently on the plan when seen by hand.

I meant whether the basement will be built with masonry or just concrete walls in contact with the ground or a retaining wall with the house in front. What is planned there?

The house is practically not touching the ground. It will be leveled off, a slab foundation will be poured, and the prefabricated house will be built on top using a timber frame construction method. Around the house, the terrain should be as flat as possible. We no longer want a significant slope on the property, but retaining walls at the front and back instead.

To clarify: retaining wall, then several meters of distance, then the house, then several meters of distance, then another retaining wall.

Ah, okay.
Sounds expensive, but that suits the house.
