ᐅ Sample floor plans for long, narrow houses?

Hello everyone,

occasionally, in the forum, it is suggested to first look at the catalog models from prefab house manufacturers for floor plan inspiration. This is where I already run into difficulties because, despite thorough research, I can’t find anything suitable.

Specifically, I am looking for example floor plans with the following rough parameters:

• Building plot 6 x 15.5 m (20 x 51 feet)
• One full floor
• Gable roof with 45° pitch, ridge running lengthwise
• Maximum height 8 m (26 feet)
• At least 6 rooms total, of which at least 5 are on the upper floor
• No walkthrough rooms
• Main bathroom on the upper floor
• Entrance on the narrow side

Please, dear forum members, don’t bother drawing anything yet. I would first need to fill out the questionnaire for that, but I’m not at that stage yet. I just want to see examples of how to fit 5 rooms and a bathroom into a long, narrow, and roof-slope-restricted upper floor. I really can’t find anything online. If any of you have come across something like this, please upload it or tell me the keywords I should use in Google image search to find suitable results.

Thank you,
yours
Pröter

Sorry, forgot to mention: I naturally found this here:

https://www.hausbau-forum.de/threads/grundriss-schmales-langes-haus-7m-mit-satteldach.40074/page-6#post-517330

But there the house is 7m (23 feet) wide and has too few rooms upstairs.

Yes, there are standard house designs available off the shelf for the general market, especially for simpler plots.
But you can find them if you search for "narrow houses" or look at semi-detached or terraced houses.

However, these specifications naturally conflict with each other

I’m not sure what you consider a “room,” whether the bathroom counts as one of the 5 rooms.

But your building envelope allows for only about 78 sqm (840 sq ft). Subtracting an 8 sqm (86 sq ft) long hallway (with dormer for standing height) leaves about 70 sqm (750 sq ft) for 5 rooms plus a bathroom of approximately 10 to 12 gross sqm (gross square meters here means floor area of the rooms, not the living area according to DIN standards).

In principle, I would recommend consulting an architect for this building envelope. Professionals learn the tricks of dealing with building regulations and challenging site conditions, and can often create solutions through setbacks, projections, dormers, and bay windows on the ground floor. They should also be able to work within tolerance limits.

In this post, I showed an example of 5.7 x 13.99 m (19 ft x 46 ft).

However, a statement like “5 rooms on the upper floor” is more than meaningless without knowing the intended use. So basically, the questionnaire is important, since the plot, location, etc. also matter. It doesn’t make much sense to name floor plans without this information. And the room layout is ambitious.
And, I understand

One full story

to mean that it should be in the roof with a sloped ceiling? Why? The maximum height would allow for more. Then just a roof with a shallow pitch.

And presumably, a side entrance would offer a better layout.

Thanks in advance to everyone for the detailed and quick replies!

I did that. None of the ones I found have more than 4 rooms on the upper floor.

No, the bathroom is not included. I count rooms as living or bedrooms—just as traditionally counted.
Specifically, upstairs we need: 2 children’s rooms, 2 home offices, 1 bedroom.

If I owned the plot (or was at least in final negotiations), I would do that as well. For now, I don’t even know if it makes sense to pursue it further, because of the issues that are also becoming clear here in this thread.

I spoke with the building authority. According to their verbal statement, dormers are not allowed because even a single dormer would exceed the two-thirds rule for the full floor. The site plan is also interpreted strictly, and none of the neighbors have dormers, more than one full floor, or bay windows.

2 children’s rooms, 2 home offices, 1 bedroom.

I understand the forum rules so that if you request full floor plan consulting with questionnaire, you also have to provide your own draft—you cannot just have one drawn for you. We don’t have a draft yet. I just wanted a random example to see how to fit 5 rooms upstairs under the circumstances of “long, narrow, sloped roof.” If it really isn’t possible, then I won’t pursue this plot further.

And the room program is quite ambitious.

Well, a family of four with parents working from home is not that unusual. But maybe ambitious for this building envelope.

Also, do I understand correctly that the upper floor is under a sloped roof? Why is that?
The maximum height would allow for more space. Then you could have a roof with a shallower pitch.

The site plan requires a 45° roof pitch, one full floor, and a maximum knee wall height of 1.8m (6 feet). This basically fixes the building volume for maximum living space.

Try looking up shotgun house floor plans. They are narrow and long, but having five rooms upstairs might be challenging to implement.
