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)

==========================================================

The stair layout will change the open-plan area again.

Sure, that's true—the space will naturally increase at least by the size of the stairs. Well, somehow I've really taken a liking to this design; it immediately feels very balanced. The pantry, which you only notice at second glance, made it even better. 🙂

Where do your guests sleep? You need a fourth bedroom, right?
Basically, there is an open space or a room on the upper floor...
What do you think?

Thank you for asking. Regarding the rooms: 3 children's bedrooms and a bathroom are sufficient for us at the moment. There is enough space for sleeping, including in the main house.

A brief digression on the topic of light and how to bring it into dark rooms. Just some inspiration...

I would actually suggest installing a frosted internal pane, a clerestory window, for example above a door, and/or three daylight panel lights in the upstairs hallway. These diffuse lights can also be used on the wall and then look as if they are windows.

I had another idea after I found a staircase at the back of the hallway quite unsuitable. This also reduces the size of the chill lounge, and the utility room would no longer be as spacious.
I’ll work on this a bit more and show it shortly.

Open living room with glass partition, bookshelves on the left, rolling ladder, and sofa.


Modern open living and dining area with dining table, colorful chairs, and large windows.


Modern workspace with desk, laptop, white built-in cabinets, and wooden staircase.


Bright interior: wooden staircase with glass railing, white walls, guitar in the background.


Bright children’s room with white dresser, toys, stuffed animal, and balloon wall stickers.


Bright interior with wooden floor, glass railing, and three dark window frames on the wall.


Bright attic with shelving unit on the right, books, green vases, dark wooden floor.


Large wooden table with chairs in open living area, view of garden.

Söööö,
here’s another concept.
The longer you work on it, the clearer the designs become 🙂
The parents’ area remains.
The staircase has been shifted, which makes the open space now more spacious and easier to oversee. The pantry is positioned centrally as a box-like division.
The kitchen is a placeholder. The island measures 3.20 meters (about 10.5 feet) as a reference—I can’t seem to save measurements otherwise. The table is also 2.20 meters (about 7.2 feet).
The staircase is scaled to 4 meters (about 13 feet) and might be shorter. The software doesn’t do dormers, or maybe I don’t know how. I’ve set the knee wall to 1 meter (about 3.3 feet) with a 45° roof pitch. The 2-meter (about 6.5 feet) line is visible.
Bathrooms are stacked vertically. Toilets are close to the soil pipe. The living corridor has no windows, but daylight lamps. The children’s hallway can be divided. There’s a home office or PC nook. If the upper roof structure is to be developed later, it would be accessed via a transverse staircase on the north wall.
I haven’t taken into account the 2.30 meters (about 7.5 feet) ground floor height, meaning the roof structure on the ground floor.
Overall, I see advantages: large open space, wardrobe and airlock inside the utility room, nearby dressing room with the parents’ area. Clear lines. Children’s section can be separated. Bathrooms stacked, living corridor...
Disadvantages: the staircase might be too close to the main entrance (1.60 meters (about 5.25 feet) wide).

Thank you. Through my own research, you occasionally come across new things, but there were two or three points I hadn’t fully considered before. Of course, not everything applies to the barn, but it’s very useful to be familiar with—and who knows...
