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)

@ypg If the wall is moved in by 60cm (24 inches), you can install windows with a height of 2.2m (7 feet 3 inches). In that case, skylights are not necessary.

If you like, I can draw up a kitchen layout for you. I just need a few measurements and an approximate ceiling height.

@ypg If the wall is moved in by 60cm (24 inches), you can install windows that are 2.2m (7 feet 3 inches) high. Then you wouldn’t need the transom windows.

Thanks – an important point: You used the wrong side of the section for your drawing; that is the north side of the barn.

The south side is opposite. In the drawing, the roof supports have already been removed there. Actually, the idea is that moving the wall in by about 60cm (24 inches) will bring it so far inside that there will no longer be a slant on the ground floor. The new wall will therefore meet the ceiling of the first floor directly (approximately 285cm (112 inches) from floor to ceiling).

Unfortunately, this section is not up to date. Sorry.

That’s very kind, and I gladly accept your offer. Wonderful. The current suggestion from ypg places the kitchen on a different side, though. I’ll still give you the measurements, and you can decide whether you want to work on it now or wait—such ideas are always inspiring. In any case, many thanks for your good intentions. 🙂

A – 662cm (260 inches)
B – 750cm (295 inches)
C – 427cm (168 inches)

In that case, a skylight is really not necessary.

I think we haven’t even reached the kitchen topic yet 😉

Darn, I think I miscalculated. I had this inspiring idea to position one room facing east and then realized there isn’t an exterior wall there.
I like the dormer idea from @icandoit.
Anyway, I’ll show the current, miscalculated draft... upstairs, the two parallel rooms are definitely not to my taste, but otherwise one of the rooms would have been too small.

I can’t save anything here temporarily. If I delete and overwrite (paint over 🙂 ), it’s gone. If I use my actual software, it would take me a week’s work.
It’s meant to be just for inspiration anyway – the ground floor ceiling height combined with the shallower roof pitch, I hadn’t taken that into account.

By now, I think you really have to move the staircase toward the back to line up the rooms like beads on a string. However, here I see:

OG-Grundriss: Treppenbereich, Luftraum, mehrere Räume durch blaue Wände getrennt.

No way to access the room on the right side of the plan because of the barrier formed by the supporting beam, or am I mistaken?

So, here is my desperate attempt (I should mention that I’m estimating a roof pitch of about 35 degrees, as I followed your dashed line).
Basically everything is included: larger living room, kitchen-living area, space for hallway cabinets and a chest of drawers, access to the utility room near the dressing room, bathroom with window, WC with window, spacious bedroom.
Modern and stylish at the same time. It’s really hard for me to scrap this design 🙁
