140 sqm, 2 children + parents, but how to best design the floor plan?

Hello

We will soon have the opportunity to purchase a plot of land for a single-family house or a semi-detached house in West Münsterland. I want to live there with my wife (and possibly 2 children one day).

Now the question is how we want to build the house. Basically, we have nothing against semi-detached houses. What has always bothered me so far, however, were the dimensions of the living room (e.g. 6 x 7 m). My living room should be rather elongated, so that the living room might be 5 x 9 m. On one side, the dining area should be connected to the kitchen and on the other side the sofa area with the TV on the short wall side (and not on the long one). At the city office today, the person distributing the plots said that it would also be possible with a semi-detached house. Apparently, I lack the imagination of how something like that could come about. The plot would be approx. max. 350 sqm for a semi-detached house (115€ including development).

Is the price advantage per sqm of a semi-detached house actually that high, or does it not make much difference compared to a single-family house (+ approx. 100 sqm plot area = +11500€)? For single-family houses, the garages of two plots can be built next to each other at max. 9m length.

It should be built without a basement (cost), therefore a large garage and a study are planned. My wife actually wants a basement, but I think it is just a storage room. However, the ground is well suited for a basement. No stagnant water or clay layers, etc. The roof is actually to be built normal. That was at least our plan. But many houses are also built with a tent roof. Does that make sense (for a single-family house)? What are the advantages?

Also, I might want a KfW 70 house. Controlled residential ventilation with heat exchanger and allergy filter would be great! I am allergic to house dust mites. In addition, I am a fan of wooden floors (maybe also for the terrace? Keyword Bangkirai). I might get it cheaper. Also, it absorbs moisture and releases it again, which is good for the indoor humidity.

Timber frame construction or solid is almost irrelevant, although we would prefer to work solid with regional companies. The total costs including the land should actually stay at 290,000€. After all, you still have to buy one thing or another later, such as a sofa, etc.

I am very much looking forward to your answers!

Hello to the dark side of the Force

I am currently building a semi-detached house and we have an L-shaped living room. Many things are possible with the floor plan. You can just Google it.
In my opinion, the saving of a semi-detached house is that you don’t need insulation or windows on one side... so it’s not really worth mentioning, rather you save square meters of land, since a (reasonable) single-family house is not possible on 350 m² because of the 3 m distance to the neighbor. But since your land price (for my standards: €350/m²) is cheap, I would build a single-family house when faced with the difficult choice!
With the €290k (complete with everything including furniture, etc.) it should barely work in my layman’s opinion, but without a basement.

hi,

so a few years ago I bought an old house. Actually, it is detached, but during GDR times no one paid attention and so one or even two neighbors built onto it. One neighbor annoys me who chops wood all the time (no matter when) and on my other end of the house there's thumping. I imagine it similarly with a semi-detached house. But that's a matter of opinion.

Regarding the floor plan: I now want to build new on my property and have almost complete freedom in size and shape. We first looked at floor plans on the WWW, but quickly realized they were not for us. So we measured our current rooms. Sufficient or not? That's how we initially came up with room sizes. In a floor plan you try to find the right positions. By moving the furniture (bed and wardrobe, tub, couch) around on the floor plan, you can see where something is still needed or can be removed. The only important thing is to draw as accurately as possible and cut out the furniture precisely. Once the floor plan is fixed, you can go out and get offers. At least that's my approach. Then you can still decide whether solid or wood.

Thank you very much for your answers! I have now made appointments with 2 architects and will casually explore how such a construction project can proceed and what costs they estimate. Actually, a house like this should probably be possible for €200,000.

When building turnkey, what exactly does that mean? Do the developers already have models of houses available that you can build from? Could that perhaps be the cheaper option after all?

I have played around with the floor plans myself using sweet Home 3D, but I don't even know where to put the garage. Because then I can't put windows on the side anymore. How big is a garage usually? 6 * 9 meters?

Ok, thanks for the note! In the first case, the lady immediately said that the initial consultation is free. For the second one, I still have to follow up. But sure, at some point they also want money. It's not that easy to make a rough sketch that includes my wishes. Everything you see online somehow always looks "basement-appropriate." Is there actually a rule of thumb to say from which sqm-price it starts to be financially worthwhile to build a basement?

So the initial consultation was somehow disappointing. I had mentioned that our limit for the house itself was basically around €200,000 (all together €275,000). The architect then said that you can't really build anything special with that. I can't quite repeat what he said either. But I found his reaction strange. Soon I have another appointment with another architect, who is supposedly on a somewhat higher level.

I am getting my plot at 50%. It costs almost exactly €50,000 including tax & notary.
