Hello everyone! 🙂

Thanks to your abundant feedback, you luckily prevented us from building a dark dwarf cave, and we completely restarted the floor plan from scratch. Now we have finally reached the point where our building start notification is with the building authority *cheers* So now it’s a four-week wait, and then construction could begin.

Below are the final floor plans, elevations, and sections. Also included is the site plan showing our house on our plot. Here is the link to our floor plan thread: https://www.hausbau-forum.de/threads/grundrissplanung-efh-massivholzbauweise-140qm-in-niedersachsen.44745/

If there is interest, I could create a small "construction diary" here from this thread… Since we are not building turnkey with a general contractor, there will surely be some avoidable mishaps, but that somehow also belongs to the experience… 😀 We would definitely appreciate feedback and will likely have some questions during the build where we will need your assistance… 🙂

A brief overview of our project:

We (m37, f30, and little m6) dream of a cozy home and were fortunate to get a plot in a new residential area in a neighboring village through the city in May 2022. The brutal price surge and material shortages almost made us give up, but in November we re-evaluated what we really want. The budget is limited, the times unpredictable, and interest rates naturally much higher than we would like… But ultimately, the decision was clear: with a lot of own effort, we still want to give it a try. Now or never, and if so, it should be a place with a feel-good factor. Those who have read our floor plan thread know: we are building a timber house. Wall construction: inside 10.0 x 21.8 cm (4 x 8.6 inches) spruce planks – 20.0 cm (8 inches) blown-in cellulose insulation – 5.8 cm (2.3 inches) spruce paneling as exterior cladding = KfW40 standard, which was important to us. The house has a continuous one-meter (3.3 feet) roof overhang. Roof insulation, visible roof structure, and *unfortunately* only a permitted eaves height of 4.00 meters (13.1 feet) according to the development plan, which was a major challenge for us as first-time builders… 🙁 But we believe we have now found a solution so that our upper floor will still be reasonably usable despite the only 30 cm (12 inches) knee wall, thanks to the south dormer for the children's rooms and the north side for the staircase.

Currently, our plan looks like this (in practice, everything will probably take 1-3 months longer anyway 😀):
Earthworks by the end of September (no fixed date yet), immediately followed by the foundation slab – both coordinated by myself. Then the house builder will come at the end of October and erect the entire house within 4-5 weeks (walls, ceilings, roof frame including insulation, windows, front door), after which we will largely handle the entire interior work ourselves (electrical, plumbing, heating) in close cooperation with professional tradespeople. Then still needed are roof tiles and photovoltaics, screed work, and flooring – nothing will be done to the interior walls; they will remain natural. All exterior work will come later and to the extent the budget (hopefully) allows. We plan to move in by Easter (yes, you can laugh now :p), but without ambitious goals, you won’t finish; besides, we will soon have drawn a large loan amount, so the double financial burden will weigh heavily on us.

In any case, this is already by far the most exciting, exhausting, and nerve-wracking project we have ever undertaken – and unfortunately, we are just at the very beginning 😀

Thank you for your reply! I wasn’t familiar with this supplier before, it looks interesting, I will request a quote.
The last quote from our house builder for a "2-story, mono-pitched roof with 7° slope, 8m x 11m (26ft x 36ft), including doors, windows, and roof with complete installation" was 186,000 euros. The exterior walls are "blue" for the EH 40 standard (and thus also qualify for the KfW 40 subsidy).

You are also welcome to name your supplier. Unfortunately, the price sounds like a shell construction house excluding the foundation slab. A seven (7) degree roof pitch is technically challenging unless using sandwich panels for the covering. The warranty limit for many roof tiles is around 21° (degrees).

🙂 The provider is Helios Log Homes from Hattstedt. It is a shell house excluding the foundation slab, at least based on my previous post with the mentioned amount, but of course, the house is not finished with that 🙂. Maybe I’ll create a post to discuss the offer, as I don’t want to take over Lotte’s topic here 🙂

We have a roof pitch of 7 degrees because the development plan limits the maximum height of shed roofs to 7 m (23 ft). Gable roofs are allowed up to 9.5 m (31 ft) high. The roof covering will also be trapezoidal metal sheets.

A log house with a shed roof covered in trapezoidal metal sheets—that honestly sounds a bit like apricot dumplings with horseradish ;-)

What exactly is included with the roof? Just the roof structure and insulation or also the roofing material and installation? The 186k price sounds extremely low for KfW 40 included, which is raising all my alarm bells—especially since I’ve read several work specifications in the log wall segment… Are the windows included built to that same standard? The roof as well? Getting the foundation slab to KfW 40 means you have to insulate underneath it… What are you budgeting for that?

Did you receive a detailed scope of work from them? Do you know how to interpret it? In other words, what can be omitted without the average customer noticing?

@Paswina

Why not start your own thread with your project, and then @11ant can invite the well-known log wall users to join in? That way, it can be properly discussed 🙂
