Solid house-single family house 142 m² living space, questions about floor plans/building costs

Sorry, search by floor plan, not by house

One more question for clarification regarding the current floor plan. What is it supposed to be, 1.5 stories or 2 full stories?

Here are a few tips for designing: I also planned my floor plan myself, and after many drafts, it ultimately ended up being almost a standard floor plan. I probably could have found something similar on the Internet. Particularly important are the elements that span across floors, such as the chimney and staircase, and the load-bearing walls. To keep traffic areas small, the staircase should end roughly in the middle. Also, you should consider where which rooms are needed and in what size. If the spaces are mainly needed downstairs, a 1.5-story design is suitable. If they are needed more upstairs, then a 2-story design. You definitely want an additional guest room downstairs that can be used as a bedroom in old age. Then the bathroom downstairs should also be age-appropriate. That means you need more space downstairs than upstairs. The utility room is a room that can be used flexibly (upstairs or downstairs).

In general, 1.5-story houses are somewhat cheaper per m² of living space than 2-story houses. I suppose this is due to the more complex rafter roof structure in the 2-story design. An advantage of the 1.5-story house is the larger storage space in the attic. A disadvantage is the larger foundation slab and thus less garden area with the same living space.

In general, it must of course be checked what is even permitted in the development plan.

3. Guest WC, assign the blind spot to the utility room

Can you explain to me what you mean by that?

5. Guest room, which is later supposed to serve as a bedroom, should also be furnished with a 2-meter long bed as well as a wardrobe with a depth of about 65 cm. So it should be at least 3.50 meters wide. Correspondingly long, so that a (double) bed fits inside.

That is certainly true. But if you really think about it, relocating the entire living area exclusively to the ground floor in old age is anyway unsuitable. Who really lives only on the ground floor and has a completely unused upper floor? Maybe you should think about an elevator to the upper floor or change the property. From that perspective, the smaller guest room fits and you still have a sleeping option just in case someone temporarily can’t manage the stairs (e.g., with a broken leg).

6. Bedroom: where is the spacious 3-meter wardrobe supposed to fit? With your slanted wall, you’ll bump into the wardrobe when going through the door. You should plan this wall straight in the next draft.

That should actually fit. I have attached the partially furnished floor plans further down in the post.

7. The orientation of the living rooms and ancillary rooms is not right. As a result, there is no qualitative living value.

You mean the south and west should be allotted more to living/dining rooms?

As Musketier already mentioned, the views with the windows should be planned at the same time. Also, place walls on the upper floor over the load-bearing walls of the ground floor. Otherwise, you will pay a lot of money for something you won’t benefit from later: the structural engineering.

That means the upper floor would theoretically have to be completely redesigned.

There are estimated drölf trillion floor plans on the internet that have planned a guest room on the ground floor. They are already finished, built hundreds of times, and work.

Just google house 140 sqm 4 bedrooms

Thanks for the tip! We have already searched for hours looking for floor plans. Surely, there are many with a guest room on the ground floor. However, on the one hand, the houses often have bay windows, which we don’t necessarily want, and on the other hand (which is the more important point) our furniture doesn’t fit in there. Except for the kitchen, we would like to take our current furnishing with us.

One more question for understanding regarding the current floor plan. What is it supposed to be, 1.5 stories or 2 full stories?

It should be a 1.5-story house with a gable roof.

In general, you have to check what is even permitted in the development plan.

Our development plan is not very tight with regard to the building itself. We are only not completely sure about the positioning of the building on the plot. We would like to attach a carport (with an adjoining shed or similar) directly to the building on the south side. We know that this will take a lot of sun from the south. But we haven’t come up with a proper solution yet.

So, and now attached are the partially furnished floor plans. Our existing furniture is included here to scale. Only the kitchen is an idea since the kitchen would have to be newly purchased anyway.

It is supposed to be a 1.5-storey building with a gable roof.

Then your m² figures on the upper floor are the floor area, but not the living area. Between 1m and 2m height under the sloping roof, the m² are only counted as half. Most of your bathroom, for example, is probably unusable.

Then your m² measurements on the upper floor are the floor area, but not the living area. Between 1m and 2m height under the sloping ceilings, the m² are only counted at half. Most of your bathroom, for example, is probably unusable.

Exactly, these are the floor areas on the upper floor. We are planning on the upper floor with a knee wall height of 1.00 m + possibly an additional row of bricks.

baumann,

let the horizontal wall between the utility room and the toilet slide down... so that the entrance to the shower, which is bounded by 3 walls, is still available (pay attention to furnishing with a washbasin), but a shelf would fit immediately to the right of the utility room door.

A knee wall of 120 is also quite acceptable.

On the topic of age + guest room: the better option is to get a small bungalow for old age.
