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

Shed roof with a 5° pitch – if that is possible, it would look something like this:
For now, I simply placed the roof lengthwise on top of the existing floor plan.
With external dimensions of 10.5 x 9.4 m (34.4 x 30.8 ft), the height must be under 2.20 m (7.2 ft) at 6.3 m / 3.1 m (20.7 ft / 10.2 ft). At a 5° roof pitch, I get a wall height of 1.93 m (6.3 ft) on the right side and 2.75 m (9.0 ft) on the left.
The window sill height in the elevation view is at 0.8 m (2.6 ft).
I’m not familiar with roofs. But this way, you would have relatively high ceilings on the upper floor. Of course, the question remains whether the floor plan should be completely changed then, or if the house or roof should be rotated, etc.

Regarding the scope of work:
I find it quite good at first glance.
I would follow up on
- Quality of the interior plaster (Q1-Q4) exact specification
- Only aluminum window sills on the outside – I wouldn’t want that; we used all marble.
- Ceiling height – rough construction dimension 275 cm (108 inches) – what is the final height including flooring? I wouldn’t go below 250 cm (98 inches).
- Roof overhangs – additional cost?
- Drainage of downspouts – what is feasible on site?
- Tiles in the bathroom also in the window area? Matter of taste.
- Lightning protection included?
- Only gas heating offered – is gas connected? Alternatives? (Major cost factor.)
- Shower in guest bathroom additional cost?One more question about interior plaster. Q2 is the standard, so shouldn’t the goal be to have Q3-Q4 in the scope of work?kaho674 schrieb:

I simply added the roof lengthwise to the existing floor plan.
With external dimensions of 10.5 x 9.4 meters (34.4 x 30.8 feet), the height of 2.20 meters (7.2 feet) must be undercut at 6.3 m / 3.1 m. With a 5° roof pitch, I get a wall height on the right side of 1.93 m (6.3 feet) and on the left side of 2.75 m (9.0 feet).
Window sill height in the elevation is at 0.8 m (2.6 feet).
I’m not familiar with roofs, but this would naturally give you quite a bit of height in the upper floor. Of course, the question remains whether the floor plan should be completely changed, the house rotated, or the roof adjusted, etc. Katja, thank you again for your work. This is exactly what we had in mind. Surely there will still be some things to adjust, but this is exactly the direction we want to go. We’re heading to an appointment now and will report back on what’s possible based on this. Regards, Frank

One more question regarding the interior plaster. Q2 is the standard, so the goal should be Q3-Q4 in the scope of work, right? You probably won’t get that included in the scope of work. In my experience, that always comes with an extra charge. Was Q2 even specified in the scope of work? I hadn’t noticed that. If nothing is mentioned, you have to expect the lowest quality. It also depends on what finish you plan to apply to the walls.

If nothing is specified, you have to assume the lowest standard. It also depends on what you want to do with the walls. We had a very good conversation. We will receive the building specifications in the next few days so I can compare them with the other ones. The price, which I prefer to mention later once everything is clarified, is significantly lower than the one mentioned here, even if we include the D-garage and all the site work. Your rough estimate is quite accurate! It is also a builder from the area and the standard used there is supposed to be identical to the last one from the other builder. This builder knows the other and their building specifications. We were completely transparent from the start.
With a mono-pitched roof, you naturally get more height on the upper floor. But this also means more small unusable spaces and square meters above 2 meters (6.6 feet). I played around with this layout a bit – and I wouldn’t know where to save space to get down to 146.9m² (1581 sq ft).
If you want to go down to 130m² (1400 sq ft), you’ll need a different design or to cut something out.
I’m also not sure if it would be comfortable to have two full rooms with ceiling heights consistently under 2.20m (7.2 feet). Is that really better than a pitched roof with a knee wall of 1.20m (3.9 feet)?
Hmm. I’m more inclined to go with the classic design.
