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 You should continue planning there. I really like what you have so far.

Söööö,
here’s another concept.

The concept is good.

Wow! I’m impressed and once again think: this works and even more… it looks great, very harmonious both upstairs and downstairs. I’ll take a closer look again and write something about it tomorrow. There are so many things I really like and I’d like to note down tomorrow what appeals to me.

What I just noticed in the upper floor, among other things regarding the lighting:
Would it be possible for Bien-Zenker to access it differently, extend the hallway toward the south, and bring more light inside with a second double casement window or a dormer window — would that work?

Floor plan of a residential house from above: storage room, three children's bedrooms, hallway, bathroom, furniture.


Sure, that would make the hallway a bit large, but if necessary I could just put an elliptical trainer there. Or simply look out the window from time to time. Or maybe a small desk with a view of the garden.

@ypg I really like what has been done so far.

I agree. This is turning out really well – I am still amazed at how this entire thread has developed. I’m not the only one either; my wife finds it equally impressive.

I’m glad if it finds approval.
Regarding the bathroom: I initially had it like that too, but I found it disproportionately large. Bathrooms that feel like dance floors aren’t very cozy or inviting; they tend to feel more like wash halls.
And I kind of fell in love with the work nook 😉 You also have to make sure the timber frame wall on the right side is showcased somehow. Maybe the timber frame will stay exposed and not become a regular wall?
@icandoit
What else needs to be done
I think @evelinoz could take care of the kitchen, or maybe...

Oh yes, and then there’s the fireplace question (I knew I’d forgotten something 🙁)

Yesterday, I took a look around our area. I saw several old farmhouses with modified roofs. Most of them have single dormer windows. I would shift the double casement window or the dormer above the staircase slightly to the east. Then, position the dormers evenly so that the distances and sizes are equal.

Coordinate this with the location of the windows on the ground floor?

Your suggestion of having a slightly larger entrance hall could also work.

Hehe, the roof windows are just placeholders for now, as are the windows on the ground floor. These can definitely be adjusted easily.
