Optimization of floor plan for detached single-family house 155 sqm

2025-01-02 13:01:52

I would probably reconsider half of the windows. I am a fan of windows and light. But a window has no place above a bed or bathtub. You yourself have noticed the ventilation problem. Then I don’t see any knee walls, which take up storage space. (Seating) windows should be planned and not just placed randomly in the plan. Here and there: "I’ll take one above the bed and bathtub, but then there has to be another one for ventilation" "Then a seating window for sitting, next to it a terrace window is needed" That’s not how you approach it, but it seems to have been done here. The south facade will probably look very "special" now.

Yes, and that is for cross ventilation when the rooms heat up too much in summer because of the too large window fronts. That will be the case here.

First of all: the bathroom is not sensibly furnished. It can certainly be done better: toilet out of sight, then it doesn’t need a privacy screen, double washbasin sideways to the window, space for a pre-wall and thus also more space for a mirrored cabinet. However: T is not magic. T is a means to give too-large bathrooms structure or to get more installation walls. I see another problem: Where do you want to store everything? Mops, brooms, batteries and spare bulbs, the quick hammer, repair paint, quick decorations, recycling trash, beverage crates, shopping bags... Cleaning supplies could go in the kitchen. The freezer is already tight and is getting a second door, which again consumes shelf space for a rack. The wardrobe is small. Unfortunately the office can’t compensate much with a cabinet either, because there are only 50 cm behind the door. A wardrobe for hanging incoming jackets should be 60 cm deep. I also criticize this above: once spare bed covers, bedding, etc. have to be stored, the dressing room will also become tight. The house is very compact. Overall, the floor area appears to be less than 155 sqm to me. The hallway is cramped. I don’t know whether the doubly unusual staircase design, namely 1. with the ridge and 2. facing the outer wall and not towards the hallway/center of the house, does the house any favors. Unfortunately, the questionnaire was not filled out!

Thanks first of all for your feedback!

We could do without windows above the bed and bathtub. In the bedroom it was mainly about ventilation (cross ventilation) again, and for the bathtub about a lot of light in the bathroom. Here, for example, the toilet window could be enlarged?

Reducing the windows of the children's rooms facing south to 2x1.20 m would be conceivable for us. Then however, the windows facing east/west would probably be necessary so that it still stays nice and bright.

Bathroom: I have already moved a lot back and forth here but cannot find another place for the toilet. It should also not be prominently in the middle of the bathroom. Maybe the washing machine/dryer could be swapped with the toilet?

Storage: We had planned the kitchen along the interior wall completely with floor-to-ceiling cabinets. The depth of the cabinet in the side hallway could really be larger, since we also wanted to store jackets there. We could move the wall towards the living room by 20 cm here. Of course, a cabinet can also still stand in the living room itself (at/on the 1 m partition wall). Then there will still be enough space for a sofa.

The technical room also offers space under the stairs. The side door primarily serves to use the utility room as a "dirt lock."

I don’t quite understand the objection regarding the staircase.

The floor area is approx. 99 sqm and the living area 155 sqm.

The bedroom was essentially about the topic of ventilation again (cross-ventilation)

But you don’t necessarily need to cross-ventilate there, since the bedroom is not facing south. Also, unlike the children’s rooms, you don’t spend time in the bedroom in such a way that you need to keep the west window open on sunny days.

Could the toilet window be enlarged, for example?

So: three windows are definitely too many. I’ll see if or how it can be improved.

Reducing the children’s rooms windows facing south to 2x1.20m would be conceivable for us. Then windows to the east/west are likely a must so it remains nicely bright.

There is a guideline stating that you should have 8% of the room area as window area to qualify as a living room. If you want it comfortably bright, you can exceed that value. So the windows should be sufficient. Here, however, two are for cross-ventilation since the children’s rooms lie nicely to the south and the windows are probably kept open for playing. On the south side, windows with a sill height are sufficient. However, I would move the window of the children’s room on the left plan further toward the center—right next to the other children’s room.

Here we could move the wall towards the living room by 20cm.

Definitely! Plan the wall so that the wardrobe and the hypothetical cabinet behind the office door can have a depth of 60cm. Think about where the TV and sofa should be placed. In my opinion, the large floor-to-ceiling window in the sofa area should rather face west. The terrace door opposite the entrance door of the multipurpose room. In the upstairs hallway, a sill window is also advisable, just like in the dressing room.

The side door primarily serves to use the utility room as a “dirt trap.”

The dirt trap is the hallway with the entrance door and the wardrobe cabinets! You don’t have to open secondary fronts if you don’t have space for them.

We had planned the kitchen facing the interior wall completely with floor-to-ceiling cabinets.

Yes, you can see that. But yellow bags, drink crates, and the mop won’t fit in there. Unfortunately, I already see this house ending up where the technical room serves as a hallway because of the buzzword “dirt trap,” the office is used as a storage room plus wardrobe, and the file folders are stored in the kitchen. I forgot: The living area is just under 5 meters wide. Since the office with 3.02 cubic meters has no room for a 3-meter cabinet, I would reduce the office by about 30-50 cm and give the hallway a bit more width for returning home.

The room is over 6! meters long! In words, 6 meters! For that, with 2.40 it is very narrow in proportion. I would say: from a 2.40 x 3.00 room, it would be easier to create a cozy bathroom. Therefore, the room needs to be structured. Personally, I am not a fan of too many walls in the bathroom, and a toilet does not necessarily have to be enclosed within the family area for me - but here, individual areas would probably bring more coziness to the room. Here are some examples. Kitchen cabinets provide storage space as well as washing machine and dryer. Windows would have to blend well with the other adapted windows.

I would like to share my floor plan with you to optimize it a bit. We are already quite far along in the planning and basically satisfied. However, we can still make minor changes without any problems. Maybe a brief introduction to us: family with two children (2 and 4). I work full-time without home office and my wife currently does not, but plans to work part-time in a home office again in 1-2 years.

I only see one "guest" instead of two home offices, so there is no reason yet to tick off the translation of the room program into floor plans. However, by "optimization" I do not mean a boost from ten to twelve percent target achievement, but rather one clearly above ninety percent. So I do not at all understand your "basic satisfaction," and honestly not the whole "why exactly like this." You have by no means yet brought me to the level of the scale of the "minor changes."

I am also unsure about the floor-to-ceiling windows in the children’s rooms. What bothers me about a parapet is that it has to be 80cm high. I would also like to plan a sort of window seat there like on the ground floor, but it wouldn’t look as nice visually since there is no fixed glazing. We also don’t have a ventilation system and therefore wanted to be able to open the window on the upper floor.

First of all, you MUST be able to open the windows in a tightly sealed new building nowadays, otherwise you risk severe problems with mold eventually. In this respect, I would reconsider the controlled residential ventilation very carefully, as it is practically not retrofittable. Surely, I would find the money elsewhere in the house project (in dispensable areas) so that I could invest it there sensibly. We can search for this together...
A window seat, for example, is something I see as a current trend and therefore dispensable, because hardly anyone really sits there when you have enough other nice places to sit; a child least of all. Now in winter, the pane is cold and in summer one is rather away from the window. A certain parapet height makes sense at least because you can place something (desk or similar) in front of it. When I see a desk with cables and a chair—and people’s legs—in the window of a room while passing by, I always consider that poor planning.

I can’t mentally fit a half-turned staircase into the floor plan. At least not without significant changes.

That’s what the planner is for, who could at least sketch it out once if needed.
Nothing is built yet, even if you put yourself under time pressure. Take enough time and resist external pressure without letting yourself be rushed; that would in my opinion be a sensible investment here. It’s not just one window or another that pinches. If you pull one thread, something else falls apart somewhere else. Better to spend a few euros more on replanning in such a project than to carve a now already foreseeable nuisance in stone hastily.

First of all, YOU MUST open the windows in a tightly sealed new building nowadays, otherwise you risk severe problems with mold eventually. Therefore, I would reconsider the controlled residential ventilation system, as this is practically not retrofittable. [...] Bay windows, for example, are something I see as a current trend and therefore dispensable,

Oops, no controlled residential ventilation? – I hadn’t noticed that at all. If I remember correctly, EH40 is even targeted – I would install it centrally in a new building today. I associate bay windows with audio books not being listened to, are those still around nowadays?

So you haven’t brought me along to the level of the scale of the "small changes" by any means.

What I mean is: I see walls depicted and examples of furnishing or sanitary objects fitted in just barely computed "successfully tessellated" in, but the staircase still breaking through above the upper cabinets under the kitchen ceiling, and the spatial program not even fully implemented at the outset. At this stage, assigning very specific positions to walls and already drawing in details such as a heating circuit distributor seems to me correspondingly only an illusion of being close to the goal.
