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)

Double casement windows with a 45-degree roof pitch clean themselves naturally. They only need to be professionally cleaned every few years.

The dormer windows should have tilt-and-turn hardware.

I was advised here to have the windows professionally cleaned. 😉

I accept that without any objection—no arguments! 😀

Some things are just like that.
Exactly.

But I struggle with lighting and similar issues. Not really a reason to want to change things in the floor plan,
I do try to optimize the lighting situation as best as I can, from my perspective and with my means. I would be more likely to add a transom window in an interior wall or, as you’ve noticed, an open void just for light’s sake…
derclaus schrieb:

The chill-out area isn’t really that lighting-critical either…
Watching TV and relaxing works best by candlelight or a floor lamp 😉

How dark do you think the lighting situation will be in the living room area at the back of the ground floor,
You could install daylight lighting for times when “normal” lighting is needed there.
derclaus schrieb:

How dark will the hallway on the upper floor behind the rooms be,
Well… with an open void it won’t be that dark in the middle section. Without an open void, I would actually use a long shed dormer and install transom windows above the interior doors. It’s a kids’ floor anyway, so that shouldn’t be a problem.
derclaus schrieb:

Could this staircase theoretically be extended by one floor to reach an attic level?
That should definitely be planned for and the staircase positioned accordingly. You’d also have to prioritize whether a less ideal staircase location is worth it in case you end up not building out the attic. A lot depends on that.
derclaus schrieb:

That way you could bring more light (for example through a double casement window) into the upper floor.
I was actually thinking of leaving it open to above anyway 😀

Screenshots before I delete them again:
This is one option with the staircase still in the existing hallway, just on the other side. Without the open space above, of course, but it offers three children’s bedrooms and space for a bathroom.

I will move the staircase further back later... that’s the idea... so that a fourth room can be created in the attic. That’s what I’m hoping for. Based on Claus’ idea.

I really like bringing the staircase forward. The upper floor is now nicely organized.

Okay, I understand, thanks. The upper floor is well organized and works. Got it. But that means it’s not possible to have 4 rooms on the upper floor facing south and keep an entrance, staircase, or hallway on the upper floor with an open space above?

I just went ahead and made some bold changes to your (previous) draft so we can understand each other better & reduced the open space above so that there is barely room left for a second window. Perhaps the entrance could also be moved further to the left side of the plan...
