Hello everyone,
Two months ago, we purchased a serviced building plot on a hillside and are currently deeply involved in the floor plan design, which is proving quite challenging due to the elevation difference.
I have been following the forum for a while and recently found a great template for our project that I think just needs some adjustments to fit our requirements. I would really appreciate your feedback and am, of course, open to criticism!
Development Plan / Restrictions
Owner’s Requirements
House Design
If you have to give up something, which details or features
Why does the design look the way it does?
We really like the design here by "kaho674." It truly reflects our ideas. The upper floor should still fit now but, of course, with our minimum required room sizes and the requirement to build only 1.5 storeys.
What is really important to us, especially since the plot is on a slope — the highest point at the street is just under 1m (3.3 ft) above the zero level and it drops 5.11m (16.8 ft) to the lowest point — is how everything can be integrated into the plot without the costs for filling and leveling running out of control. We have also considered an alternative to the urban villa in the style of a split-level house. What have your experiences been building on such a plot?
Many thanks

Here’s another example with a space-saving staircase.
Unfortunately, I’m not sure how to calculate the two-thirds correctly because of the wall thicknesses. But it might even be enough for a third gable in the dressing room, with a knee wall height of 1 meter (3.3 feet), if I didn’t make a major mistake in my calculations.

... by the way, what is the total floor area you get for the entire house?

... can you tell me how many square meters you end up with for the entire house? No idea. The areas under the sloped ceilings are only counted at 50% up to 2 meters (6.5 feet) height. That’s why houses with a gable roof often have a larger footprint. I haven’t calculated it yet, and my software can’t do it either. But yes, I’m afraid that with 140 square meters (1500 square feet), it will start to get tight.
That’s what I meant – you want a walk-in closet, bathroom, two kids’ rooms + bedroom upstairs, and the total area quickly adds up.
Franky, given the sloping site, I would suggest considering moving away from a "conventional" floor plan. Since there is quite a steep slope, split-level designs might not be the best option (but you could take a look at matte’s house here, which to me is a brilliant split-level solution).
However, the slope can be utilized effectively. Without further details, this basic idea comes to mind:
Very schematic: Two levels, offset from each other. If I understand correctly, the lower level must be embedded quite deeply into the ground (the terrain profile is shown by the red line), and to meet the building regulations, it might need to be built further into the earth on the sides, meaning windows only at the front.
The advantages are likely less earthwork required, a fantastic terrace on top, and still plenty of sunlight below (in contrast to a balcony where it tends to be darker underneath). From the street side, only one level is visible. The design could be modern with a flat or mono-pitched roof (if allowed by building permit / planning permission), or—as I understand you prefer a more traditional style—also with a gable or hip roof on top.
If planned carefully, the large terrace could lead directly to the garden, especially if the lower volume is set slightly deeper into the ground.
Just a thought to get started, without suggesting room layouts or similar. In my opinion, this would be an optimal way to use the plot without forcing a house designed for a flat site onto a steeply sloped terrain, which usually only results in poor compromises.

... so, how many square meters do you get for the entire house? I calculated it. So, in the latest design, it's 139.4m² (1500 sq ft) net and 147.8m² (1591 sq ft) gross.

Matthew0317 Jul 2018 14:06This thread is driving me crazy... the accident metaphor fits well, the original poster should be really grateful that Katja has such patience and mindset...
P.S. When I scroll, the word "team leader" jumps out at me from the profile on the left... and I’m itching to ask if this "style" is also how "team leading" is done there.
