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.

House design
Designer: own design
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)

How and where were you thinking of placing the fireplace? I can’t find that part anymore.

Originally, I had planned it in the current kitchen area (at the corner towards the living room). Now that the kitchen has moved, the only option left is the wall opposite the couch, right?

You can nicely integrate a bench seat with the kitchen setup, running it along the length.

That will look really nice, I agree.

I imagine it might end up being neither here nor there. I can try moving things around later…

That would be great if you could rearrange it. I can follow your explanations perfectly.

Ultimately, you should consult your professional about the implementation—costs also depend on how straightforward the construction is.

The professional is up to date on both floors. He thinks the ground floor (and he knows the latest version) is not only very well planned but, in his opinion, “the designer already has the costs in mind”—meaning there shouldn’t be any significant additional expenses or complicated masonry details that would increase time and costs.

At the end of today, I’ll probably send him the current plans, and he will provide feedback on the costs soon. I’m curious to see what he says…

Maybe another location will turn up, for example near the space where the pantry is now. But honestly, I’m open to ideas, although the connection between the sofa and fireplace does seem obvious. 😎

PS: Wishing everyone a good start to the week!

How is the chimney going to be constructed? It will need to be quite tall. That will require a significant amount of money.

Thanks for the note. That’s right, the structure gets taller as you move further toward the north wall. The following locations were initially considered for a masonry chimney (before the kitchen was relocated), but I can’t say more about the costs at this point—I would need to discuss this with the site manager, which will happen by Wednesday at the latest.

Maybe we should set the costs aside for now and focus on finding the most suitable location (or just wait a bit)?

Addendum regarding the fireplace:

The costs related to the fireplace are less significant concerning its location. The fireplace is expected to end up in the corner of the sofa area. Whether it is positioned slightly closer to the ridge of the barn (and thus, for example, becomes about one meter higher) or not, does not make much of a price difference.

Perhaps the corner of the sofa area currently occupied by the pantry could also be considered. However, I would be reluctant to give up such a pantry completely, no matter where… but off the top of my head, I don’t know where it could be relocated in that case. Maybe it might help to take a bit of space from the hallway connecting the main house to the barn/stable.

I have simply marked two possible positions on the ground floor and upper floor plans to roughly show the fireplace’s path. I would like a fireplace that wraps around the corner and is also visible from the living room. However, this might break up the clear distinction between the dining room and living room and cause some disturbance. Hmm?

Gas fireplace on the exterior wall??

Or as a room divider to the living room?
