Hello dear forum members,
I have been quietly following the discussions for some time now and am curious to share the first drafts of our house construction project—to see what feedback I get. I can hardly imagine that anyone outside of this project can really understand it, but I will do my best to make the introduction as clear and informative as possible.
Background:
About two years ago, my family (wife, three children aged 7, 5, and 3), my sister-in-law, and my parents-in-law moved to an estate near Oldenburg. The estate measures about 3.5 hectares (including 2 hectares (5 acres) of pasture for my sister-in-law’s horses). Over the past few years, we have been almost daily occupied with restoring the estate and maintaining the surrounding land and large areas.
Current Status GROUND FLOOR
Together with a friend (a carpenter and exhibition builder), I started planning the conversion of the barn belonging to the estate to create an apartment for my family. However, most of the work comes from me; my friend only gave me some initial support and is not further involved in the project. The usable footprint is predetermined because part of the barn must remain storage space for equipment, etc. We have already made several drafts, and I would like to share what I consider the best ones here. Overall, we are quite satisfied with the ground floor approach, but the lighting situation is particularly challenging since windows can only be placed on one side—as only the south side of the barn can be converted. The plan is to include a living-dining-kitchen area with a fireplace, staircase, utility room, master bedroom with walk-in closet, and a full bathroom preferably with a bathtub.
An important note: two pillars (30x30cm (12x12 inches)) run from the floor all the way to the roof. These cannot be altered for structural reasons and also affect the layout of the upper floor, including room arrangements and staircase positioning. We have fixed the south side width at 14–15 meters (46–49 feet), with a maximum of 16 meters (52 feet) possible, but no more.
Current Status UPPER FLOOR
So far, I have only worked roughly on this level since I am still not satisfied with the ground floor layout. I have attached a rough draft for the three children’s rooms and the bathroom.
It is important to note: at this level, there are additional supports branching off from the mentioned pillars, running diagonally from the floor to the ceiling toward the north, which cannot be removed either. In my opinion, these should be incorporated into the walls. A door could be installed at the outer edge of such a wall. But we have not reached that point yet...
Information about the FLOOR PLAN PLANNING:
As far as I can judge, not all details (such as floor area ratio, gross floor area ratio, etc.) are relevant for this existing building construction. I will provide these as far as possible and will do my best to answer questions from the community.
From my side GENERAL COMMENTS:
I welcome any and all constructive feedback and will not be disappointed if it challenges my views on how everything should look. At this stage, any aspect or wall can still be changed. I’m looking forward to it.

What do you particularly like? Why?:
- We really like the ground floor with its large south-facing windows; it’s necessary to bring light into the barn’s interior and the far corners of the living room
- The access to the parents’ area is not directly from the hallway. Even though it costs space, I like it this way.
What do you dislike? Why?:
- I am very undecided about how to fit a bathroom on the ground floor.
- The big question is whether the living room should extend to the rear wall. I think there's still light there, but I don’t quite know how to best use the space. Or should a staircase be placed behind it?
- The access to the living room is unclear to me. On one hand, we prefer it to be closed off; on the other, keeping the option to open it up sounds interesting—possibly with a sliding door.
- We like seeing the staircase from the entrance (rather than hiding it in a dark corner).
If you had to give up on some details or features,
-Could you give up on: bathtub in the bathroom next to the parents’ bedroom; a shower is sufficient
-Cannot give up: office (could also be located in the attic; currently, there are alternatives in the main house)

I thought until post #19 that the floor plans came with the photos. The interior photo clearly shows both the ground floor and the upper floor... that was somehow wrongly phrased. However, the cross-section is confusing to me when I look at the staircase. Question: does the ridge of your future house run parallel to the south side? The gables are on the east and west, while on the west the building continues attached? Thank you for asking.
The staircase shown in the section is not correct. The drawing together with the photo is misleading, and I hadn’t considered that. The staircase on the plan is completely fictional; it was simply drawn as a possible stair location—while the staircase in the photo is currently only temporary and will be removed entirely.
Answer: the ridge runs completely parallel to the south side. The barn gables are therefore on the east and west sides. On the east side it is free (and our construction does not extend that far), and on the west side it is not visible because it continues into the main house.

For example: 10 m (33 feet) wide, 1-2 m (3-7 feet) deep, 6 m (20 feet) high. Leave the western side 3 m (10 feet) and the rest on the eastern side as brick wall.
Or start the extension at the first small window on the west and end at the third window. I can’t really imagine that, and I think it would change the character of the barn too much. Gables in general would be possible – but we would prefer to avoid them due to cost. We also considered a cross gable at the entrance but are concerned it might alter the building too much structurally and ultimately damage its visual appeal.

Today we found out that the roof has a pitch of 45 degrees. Due to the discussion about the height of the south side, we had it checked. This now results in a height of just under 280 cm (110 inches) on the south side.
Thanks for following up here, it really helped to "shed some light on the matter." 🙂I need to ask again, maybe for a beginner. Why should the south side suddenly be 2.80 meters (9.2 feet) instead of 2.30 meters (7.5 feet)? So the eave height is 2.80 meters (9.2 feet)? I can’t imagine that based on the pictures. But probably I’m missing something.
Personally, I would say that if the (dormer) gable either adapts to the historical conditions or, on the complete opposite, stands out as a modern eye-catcher, it can look very appealing. Of course, that is a matter of taste and budget.

I need to ask again for a simple explanation. Why is the south side suddenly supposed to be 2.80 meters (9 feet 3 inches) instead of 2.30 meters (7 feet 7 inches)? So, an eaves height of 2.80 meters (9 feet 3 inches)? I can’t imagine that from the pictures. But I’m probably missing something.
Personally, I would say if the (cross) gable either adapts to the historical context or, on the contrary, stands out as a modern eye-catcher, it can look very appealing. However, of course, that is a matter of taste and cost.From the pictures, it’s not clear – the visible wall will be removed and replaced by a new wall set 60 cm (2 feet) inward. But that shouldn’t be the main point of my post – I’m specifically concerned about the layout of the rooms on the ground floor.
Visually, I understand your opinion about the cross gable. It can really look nice, but it will probably not be feasible for cost reasons.

... if it is to be renovated — which I do not see as necessary, mind you — then it can also be redesigned (although the regional characteristics of the house are basically built into the construction)...Regarding the pillar and the beam: the beam is needed due to the extreme wind load on the building. The north wind exerted so much pressure on the roof that, for example, the south wall became completely tilted. Therefore, it has to be rebuilt (and will be set back around 60cm (24 inches) to the inside in order to increase the height of the south side).
Okay, I don’t have any more input on the pillar/beam or the south side and its corresponding height/eaves.
Thank you very much for your questions, which encourage me in turn to initiate one topic or another.
