Prefabricated wooden house provider for single-family homes in Lower Saxony

Hmm, with a 36.5 cm exterior wall (with clinker), I would be very interested in the intended exterior wall structure... (especially with timber frame construction)...

Our living habits are probably relatively average in the end, meaning we would have been happy with a proven standard floor plan from any prefabricated house provider. The main reason for the architect was primarily to have a uniform basis for comparing offers.

Requirements for the planning were: 2 roughly equally sized children's rooms on the upper floor, separate children's bathroom, study room with space for 2 desks on the ground floor, no open living-dining-kitchen area or the option to visually and olfactorily separate the kitchen from the living/dining area, sauna in the master bathroom, and a bay window facing south in the living room.

That's why I ask, because the house with everything included will easily cost 750k in this form. Hence the question whether it financially fits for you as well. Personally, I find the option of two guest rooms already a lot. You would definitely also have options to accommodate technology there.

Otherwise, I also like this floor plan by Mrs. Forster again. I would swap table and toilet in the children's bathroom. The wardrobe on the ground floor could definitely be shorter and has a lighting problem in the long section, as far as I can see.

Thank you very much for your feedback!

In my eyes! Either you plan a house that deliberately uses symmetry or another house shape.
If it doesn’t bother you, then there is no need to change anything.

It does bother me. I just can’t say yet whether it bothers me enough to start planning from scratch again. The asymmetry of the sides is 89cm. If you enlarge the left side by this length, the house gains 8.2sqm more space and costs about €30k more + the costs of replanning. In the guest WC downstairs, the window could be positioned in the middle; upstairs, the current bathroom layout lacks 7cm. Functionally, a bathroom 89cm wider in the current layout upstairs probably doesn’t bring much. Effects on the ground floor layout: no idea.

Otherwise, I miss 20cm length for a comfortable sauna

I will use that alone and lean my legs horizontally against the wall. So, the size fits.

and to me there are too many sliding doors, which are uncomfortable for me in the living area.

Good point. Our thought was that the kitchen sliding door would be closed a few times a week while cooking and otherwise mostly open. The door to the living room might really be better as a double door. I somehow can’t really judge yet what is more practical there.

The hallway with 15sqm is just as large upstairs

Upstairs the hallway is only 9sqm and 1.15m wide. Is that rather large? Downstairs, it also serves a storage function in the area of the side entrance.

square floor plan for the so-called city villa etc., all money/space wasters, also clinker.

The floor plan is definitely not square. Clinker is purely aesthetic, but I just can’t imagine the building plastered, and it is also not primarily permitted by the development plan. Pure wood doesn’t fit well in the region either and also has its disadvantages.

I find the cellar optimistically calculated, reality often shows it tends to be more expensive, but ultimately you each will have your reasons for it.

You’re probably right there. I do have a certain cellar bias. If I try to calculate objectively and take the €2,000/sqm from ypg, the costs are €180k. From that I can subtract €15k for the base slab, €36k for 10sqm of technical room above ground, and €13k according to 11ant’s cellar formula. That leaves €116.5k. For that I could create 32sqm better living space upstairs (assuming the development plan allows it). On the other hand, laundry, storage, and technical rooms can also do without equipment. Assuming I get by with €1,500/sqm there, then the extra cost is <€100k. The question is whether we really play that much table tennis.

Hmm, with a 36.5 cm exterior wall (with clinker) I would be really interested in the intended exterior wall construction... (especially with timber frame construction)...

Yes, here again is the error mentioned by 11ant of a design planning not adapted to the type of construction. What does timber frame construction stand for in this context?

Thank you for your feedback!

I ask because the house with everything included will easily cost 750k in this form. Hence the question of whether it also financially works for you like this. Personally, I find the option of two guest rooms already a lot. You would definitely also have the possibility to accommodate technology there.

Unfortunately, that will probably not be enough. Assuming €3,600 per sqm, my initially estimated €125k for the basement, and 18% ancillary construction costs, I am currently calculating rather with €900k. A slight shift in the sqm prices between basement and house is of course possible.

I would swap the sink and toilet in the children's bathroom. The wardrobe on the ground floor could definitely be shorter and has a lighting problem in the longer section, as far as I can see.

We intuitively found the sink by the window more appealing than the toilet, especially since that faces directly onto the street. I fully agree with you on the lighting in the entrance. In the initial draft there was still a door between the entrance and wardrobe that we removed for practical reasons (who likes opening four doors to bring groceries from the side entrance into the kitchen, especially since the route is already quite long), but also for lighting reasons. I wouldn’t have minded a somewhat wider main entrance area with more light, but the staircase does somewhat limit the possibilities there.

Yes, there is again the error mentioned by 11ant of a design plan not adapted to the type of construction.

36.5 sounds monolithic to me at first. So no clinker. With insulation and air space it will also be thicker, hence the question. HRB with wooden facade can be done reasonably well. It gets tricky when setback areas are fully utilized, floor area ratio is maxed out, then the whole planning is screwed. In Lower Saxony, remember the roof overhangs, from 50 cm they are included in the floor area ratio.
