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)

Hey Claus... why do I have the offset in the top left corner of the attic floor plan (carried over from below) and you don’t? Did I miss something?

Damn, I think I miscalculated.

Oh, I’m sorry to hear that. It’s a shame about the effort, but I still find it very interesting.
ypg schrieb:

The upper floor’s two parallel rooms are definitely not to my taste.

I can understand that and could live with it too. Of course, nobody wants to build a hospital, but the issue of “compromise” is definitely present. 🙂
ypg schrieb:

It’s meant to be just inspirational anyway.

That’s exactly how it should be, and that’s how I see it.
ypg schrieb:

I now think that the staircase really has to be moved to the back so the rooms can be lined up like pearls.

That would be a bit of a shame, because I really like the central staircase, whether it runs crosswise or not, no matter. On the upper floor, I’d be willing to make compromises there, such as regarding room sizes.
ypg schrieb:

But I see here... no possibility to access the room on the right side of the plan, since there would be the barrier of a support beam, or am I mistaken?

Absolutely right. That wouldn’t work and is confusing. Sorry about that.

The desperate attempt can be seen here:

I find that desperately clever—actually devilishly clever! 😉 Of course, the room on the east won’t work like that, but the open design, the staircase going up, the void/gallery space... impressive, and I also find the upper floor stylish and modern. Wow, wow, wow, a great approach overall. Maybe you could still manage one room facing south by giving up one of the skylights or reducing the void. That’s my first thought, quite spontaneously...
ypg schrieb:

Basically everything’s included: larger living room, open-plan kitchen/living area, space for hallway cabinets and dressers, access to utility room near the dressing area, bathroom with window, toilet with window, spacious master bedroom.

That’s a really nice surprise for me right now. I’m looking at all of that closely and thinking: this actually works! Maybe I’m not seeing it too critically, but simply put: I don’t see a single flaw regarding the fundamental layout, room sizes, circulation, etc. What really impresses me is that both the bathroom and guest toilet are placed on the south side, and on top of that, you don’t enter the bedroom directly from the hall... wow! There’s also a large utility room/mudroom, the living area clearly separated within the open space, and from what I can see, everything works so far. There are further details, small but clever: the door to the open living area opens nicely thanks to the shifted staircase (between two walls), I like that too. And how the columns downstairs are integrated—it’s really smart in my opinion.

Really great and on a fascinating path—would be a shame if it didn’t work because of the upper floor.

PS: I hope you also had a nice sunny day. We had a wonderful one and I hope you/you all did too.

Yes, there is still some space left. On the ground floor, there is that corner because you can go from the back part of the main house into a hallway (which then leads to the saddle chamber). In the upper floor, it’s different; that area is available as usable space. Sorry for not making this clearer.

There is one more small point about this corner on the ground floor. I hadn’t mentioned it, and maybe it doesn’t matter. You could take a tiny part of that hallway and add it to the ground floor’s floor area (150cm x 100cm (59 inches x 39 inches)) — unfortunately not the full width of the hallway, because in the small recess of the hallway there is the electrical cabinet for the site. We would prefer not to move the cabinet, as that would be unnecessarily expensive. I just wanted to mention this — maybe you thought there’s about 1.5m² (16ft²) missing — although I doubt that... 🙂

Wonderful: slept in, breakfast in bed, sunshine filling the rooms, an amazing walk at minus 2°C (28°F), then an hour of space planning, painting furniture, shopping, and while the washing machine was running, more space planning for Claus’s family. The evening started with oven-baked cheese by the fireplace...

Okay, then I’ll include the corner in the upper floor as well, it’s needed. And the ground floor on the east side probably won’t be touched anymore 😉
Otherwise, there will probably be some rearranging again, and I’ll let @evelinoz know when the open-plan area is finished 🙂

"During the World Cup" sounds good. Everything else as well.

How do you plan to provide natural light to the rear rooms in the attic?
