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)

This is what I mean here. 🙂 I already think it’s really great. Maybe you can identify something you find “problematic” or can imagine improving, but as far as I’ve thought it through so far, I find it very good.

Rooms 4 and 8?
It clearly says that I miscalculated with the east side... everything is already deleted!

Okay, great. I also like the parents’ area 😉
The open-plan space will change again due to the staircase arrangement.

(A) How dark do you think the lighting situation will be on the ground floor in the couch area at the back? Can this be estimated or maybe compared somehow?

Perfect is different. White walls help a lot. I would make a TV corner there anyway, so not much light is needed. Compromises!

(A) How dark will the hallway on the upper floor behind the rooms be if we add a dormer with one or two windows? Are the corners very dark?

Same as before. Window area helps, which is why I suggested the bay window. You can install tall windows there.

(C) And one more question about the staircase, which could partly affect lighting (without considering the cost for now): Is it theoretically possible to extend this staircase by one floor to access an attic? This would allow additional light (for example, through a double casement window in the upper floor). Would something like this be technically feasible (staircase + light from there)?

A double casement window with a light shaft is also possible without a staircase. It’s a matter of cost. I have 4 double casement windows electrically operable at the ridge. They bring light all the way down to the ground floor. Before the renovation, even down to the basement. 😎

Many thanks if someone wants to comment on this.

You're welcome.

Thank you very much. From the ridge to the basement or ground floor—wow.

The bay window feels a bit too large for the entrance area. I’m already thinking about how to clean the windows there—whether they are double casement windows or a continuous dormer is built. But neither option is a "bottleneck"—I do want to have natural light in the hallway.

Maybe in the rear part of the upper floor, it’s worth keeping the option open for a staircase to the attic and initially using that space as a TV corner or something similar—that’s a good idea. That’s how I’m thinking about it at the moment. There’s also the idea of expanding further upstairs, although I expect that to be very expensive (an additional 90m² (970 square feet) plus insulating the roof area, flooring, and so on)...

The stair layout will change the open living space again.

The master area is excellent. I once posted a version with access through the walk-in closet, but you managed to make that access more comfortable, even fitting a bathtub in the bathroom, and lastly: a guest toilet by the window. I still can't get over it!

I showed it to my father-in-law today, who is an engineer and heating specialist by profession and doesn’t hesitate to give direct comments or criticism: he was just as amazed, and I’m specifically told to pass on that he is “enthusiastic.”
