Hello dear house building forum!
Here are some details—based on our best knowledge and judgment—about our house construction project...
Development Plan/Restrictions
Plot size 576 sqm (approx. 6195 sq ft) - parcel 17/28 (see cadastral map)
Slope no – the plot has only a few centimeters (inches) of elevation difference
Floor area ratio (FAR) 0.3 = 172.8 sqm (1861 sq ft)
Plot ratio not defined
Building envelope, building line and boundary 24x24 meter (79x79 feet) plot = N-E-S-W 16x18x16x18 meter (52x59x52x59 feet) building envelope
Edge development no, exceptions possibly according to Lower Saxony Building Regulations
Required number of parking spaces not specified
Number of floors single storey
Roof shape gable/hip/half-hip with 35-50 degree pitch
Architectural style classic detached house
Ridge direction specified = ridge line running west-east
Max height limits ridge height 4.0 m (13 ft), eaves height 8.5 m (28 ft)
Additional rules no oil heating, 50% of the south-facing roof must have solar panels, no building allowed between house and street (e.g., no parking or similar in front yard)
The plot has been purchased and the utility infrastructure in the new development area is already completed (our plot is even located on a pre-asphalted road).
Homeowner Requirements
Style, roof shape, building type solid wooden house made of massive log beams inside, blown insulation, and exterior cladding
Basement, floors no basement – only ground floor + upper floor
Number of occupants, ages three, aged 36, 29, and five and a half
Space requirements on ground and upper floors standard single-family home with 3 bedrooms plus bathroom upstairs, open-plan living area downstairs, guest WC, and large utility/housekeeping room
Office: family use or home office? One room currently usable as office/guest room (backup for future child needs), currently neither of us have jobs with home office option
Open or closed layout living/dining/kitchen preferably open
Conservative or modern construction style conservative
Open kitchen, kitchen island open kitchen yes, kitchen island currently not planned
Number of dining seats daily use for 3, but dining nook should be sufficient for more people
Fireplace planned is a masonry stove
Music/stereo wall no
Balcony, roof terrace no
Garage, carport carport with workshop
Utility garden, greenhouse no
Other wishes/special features/daily routine, including reasons why some things are included or excluded
House Design
Who designed the plan: plan based on our principles, then optimized with the manufacturer’s in-house architect
What do you particularly like? Why? We really like the extended dining nook with the surrounding bench; overall, our ideas about room sizes have been well implemented – whether everything will really work as we imagine, we would like to ask here.
What do you dislike? Why? The chimney’s position might be bothersome in the children's room? Or is that negligible in daily life? We are still not satisfied with the kitchen and bathroom upstairs and are currently looking for a good furnishing/decorating solution.
Price estimate according to architect/planner: Since we are not working with a general contractor but will handle contracts ourselves after the shell is built and do a lot of work ourselves, we don’t have all numbers yet. The following trades are currently being costed.
Personal price limit for the house including fittings: 400,000 up to move-in ready, excluding everything outside the building itself, plot is paid
Preferred heating technology: heat pump with underfloor heating plus photovoltaics with possible storage
If you have to give up something, which details/extensions
- can you do without: We have tried to adapt our demands to the budget as much as possible – does anyone see further savings potential?
- can you not do without: As an absolute last resort, we would remove the dining nook and redesign the ground floor – also, the masonry stove is fixed for us (we just love this cozy atmosphere).
Why is the design the way it is now?
Standard plan from planner? The manufacturer does not offer standard houses; everything is individually designed
Which of your wishes were implemented by the architect? The current plan reflects our wishes quite well. Now we just need fine-tuning, and we hope for your assessments, ideas, and experiences.
A mix of many examples from various magazines... Of course, our inspirations come from many different sources (good and bad…) 😀
What makes it particularly good or bad in your opinion? It feels good to us so far – all our furniture fits, and the things that bother us in our current rented house have been eliminated in the design.
What is the most important/basic question about the layout, summarized in 130 characters?
- Does the layout work as it is, or are there specific arrangements that don’t work?
- Is the position and number of windows sufficient?
- Do the children's rooms upstairs need two roof windows or is one enough each?
- Have we missed or overlooked anything important?
- Can a U-shaped kitchen be sensibly planned in the existing space, or do we need to adjust walls downstairs first?
- Are the door positions appropriate regarding width, wall distance, and opening direction?
- Is the utility room (unfurnished room behind the laundry on the north/east side of the ground floor) dimensionally adequate?
- What knee wall height is recommended upstairs? Currently at 40 cm (16 in), we plan to raise it because otherwise, especially the upstairs bathroom will be problematic (though we don’t want a large bathroom, just “as big as necessary” – we would probably place the bathtub in the northeast corner of the room – would that fit?
- We’d like to add a laundry chute from the upstairs bathroom to the utility room – does anyone have a good idea for the best location?
One final note on our general concept:
We intend to buy the house from the manufacturer including insulation, cladding, and roof structure. Assembly will follow the “master carpenter assembly” principle (the company provides two experienced workers, plus 4-5 helpers from us – full warranty and savings of around 15,000-20,000 euros, about three to four weeks of hard work). The manufacturer’s “basic package” also includes windows and the front door, as they must be specially installed due to the house settling.
We plan to contract the foundation slab, roofing, and plumbing work separately. Electrical work (in consultation with the local master electrician), interior finishing (room doors, screed, underfloor heating, floor covering), and small tasks can be done by my partner (trained electrician, highly interested in almost everything, skilled and experienced with wood). I work professionally in an office of a building materials supplier, so I have access to good conditions, storage capacity, and established contacts in the industry. We also have great friends and a large family who are all enthusiastic about our project and willing to support us. We know this will require a lot of work, strain our time, nerves, and budget—but we want to give it a try.
We are now looking forward to suggestions, critical comments, and anything that can help us avoid as many mistakes as possible during the process.
Thank you very much in advance!

the rest of the ground floor could stay the same Never!!! There is nothing more pointless than sticking rigidly to previous plans in some areas when fundamentally changing direction. That only becomes a burden for the next design phase. So never reshuffle only part of the cards!

@WilderSueden The additional cost for KfW40 (although I’m not sure what the reference value is) is around 10,000 euros. They would even be NH certified.With a shell construction package, I would be cautious about those figures, as well as the NH certification. It is quite likely that additional costs for on-site services will come up. The related materials would presumably also need to be certified, and that sounds like a real hassle to me. -LotteS- schrieb:
Just read today that there might be funding up to 100,000 euros for KfW40 even without NH certification? Does anyone have more detailed information? I haven’t found anything yet... It would probably be worth running the numbers anyway.I have seen an article about that too. However, it was full of terms like “up to” and other uncertainties. I think we should wait until the details are clearly published on the KfW website.N

I’m bringing @neo-sciliar into the thread, along with the question of whether Stommel also offers shell houses 🙂Answer: yes. They offer several finishing stages. The classic is the shell house (only the walls, windows, doors, and roof are in place), then the structural shell (roof covered, insulated, drainage, etc.), followed by the technical package for electrical, plumbing, and heating, then flooring, painting, doors, and stairs.
I only read the first page of the thread (I stopped at the poster’s wall construction, it’s not my area). Why Stommel?

neo-sciliar24 Feb 2023 12:56@-LotteS- to Stommel: We have built with them twice, most recently in 2021. They’re definitely not cheap, but the quality is solid.
I read earlier about the wall structure: log beam – insulation – log beam. Are you sure you want to build it like that? How is the cladding over the windows and doors designed? What does your insurer say about that? How are the interior walls constructed? How are the house corners executed? What supports the roof? I have lots of questions… Would you like to discuss? I’m happy to. You can also ask @11ant, who now enjoys walking in Posemuckel and is quite convinced by Stommel.

@11ant You haven’t been around for a while, otherwise you could tell the difference between sky blue shades. But it makes sense, as we are almost far away from main roads, yet so close. Almost perfect. In the village – now even with a sky blue house, and that from the timber house supplier with an S.Are there about 50 shades of sky blue that I still need to learn to distinguish – and how do you know I haven’t been in Posemuckel/Ww. for a while? – I come with different cars... I have known Stommel for a long time – it was only your house that convinced me that a Stommel house also fits in Posemuckel/Ww.

Why Stommel?Because I consider Stommel here a more suitable supplier (experienced in production homes) than the one who hides their lack of experience behind client-specific planning excuses. If you want a Canadian-style handmade log house, I would consider Charlie Manz. If you can imagine building with solid wood but without a prominent wood surface, my recommendations would be Staudenschreiner or Wirlebenhaus (see @Climbee and @haydee).https://www.instagram.com/11antgmxde/
