ᐅ Design for a Single-Family Home of 160-180 sqm – Suggestions for Improvement?

We are not talking about spiral staircases, but about stairs that turn once or twice.

Actually, this is mainly about stairs, garages, and basement design or temperatures.

I also had a few other questions, like whether a window is required in a garage when it’s located in the basement.

I assume some kind of thermal door or fire-rated door is needed at the transition, or can a standard door be used?

Personally, I can’t safely navigate either a curved or spiral staircase in the dark or when intoxicated. Doubling the floor area would mean a 360–380 m² (3,870–4,090 sq ft) house—that seems a bit oversized.

You could also settle for 250 to 300 m² (2,690–3,230 sq ft) and place the second staircase above the first, or manage the intended size sober and with a flashlight. Straight staircases unfortunately disrupt the floor plan; or to still have reasonably generous usable areas requires a corresponding amount of space.

We have 190 sqm (2,045 sq ft) and a straight staircase. It just fits.

Whether windows are necessary is something the architect needs to decide. The best location for the door also depends on that. Since you are planning an unheated basement, I would say the door should be placed at the top of the stairs.

However, your living room will not have a southwest-facing terrace.

And I keep asking myself why someone would plan such a large ballroom as a bedroom while making the bathroom and dressing room so small.
Sorry, but regardless of the main issue with the "staircase," nothing about this floor plan is right yet.
Visit a model home park – this suggestion has already been made – and first get a sense of the dimensions.

The rooms actually fit pretty well as they are currently planned. One guest room and one office, guest bathroom, etc. Children are not planned at the moment, but otherwise, you would have to repurpose one of the existing rooms. The terrace should face southwest, so in front of the living room. Access from the west; of course, this means you step out the door a bit directly, but going the other way doesn't make sense.

Strange. I seem to recall someone complaining about a basement that is not really needed. But the room layout fits fine.

By now, I’m not even sure if I had the right plot in mind. Attached is the placement as I understood it (red = house, gray = driveway, beige = terrace).

Unfortunately, there are no dimensions here – I don’t have a good sense of how big this would have to be. Still, I think the distances to the west and north will be quite tight. Won’t your terrace end up right next to the neighbor? And it’s almost impossible to reach the garden in the northeast. At barbecues, everyone will be practically sitting on the neighbor’s lap. The garden behind the house remains unused.

If it were mine, the kitchen would be on the east side with access to the garden. The terrace would wrap around the corner from east to south, and the living room would be on the west side.

Depending on the type of street (play street or highway), you could also place the house further to the northeast and access it via the dead-end road. Then you’d have sunlight in the garden, a view from the hill into the valley if I understand correctly, and could possibly save a floor by combining the basement and ground floor. In that case, parking spaces with a carport would be located to the north.

The children’s room or office would then be in the basement along with the technical/utility room and a small bathroom. Upstairs would be living, kitchen, bedroom, bathroom, and the rest – possibly with more space than the basement. Sort of a bungalow with the children’s area separated in the basement.

Or do you really want to have the smelly cars in the basement?

So, the way you placed it in the first picture should be roughly correct. However, I don’t understand your point about the terrace and the neighbor. The plot is basically bordered by the street—it’s a traffic-calmed residential street. There should still be about 10m (33 feet) of space at the end when placing it. I think access from the north is quite difficult because you would have to drive very carefully around the curve—and you obviously cannot cross the neighbor’s property.

For me, the bedroom is more of a multipurpose room that is used frequently, with a large stereo and TV system, etc. Therefore, it should be somewhat larger than just enough space for a bed.
