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!

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

Mono-pitched roof with a 5° slope – if that's possible, That works: but in the wrong direction. To avoid a full story, the roof must slope down on the eaves side, which becomes increasingly difficult with shallower pitches.

I also don’t know if it would be pleasant to have two full rooms continuously under 2.20m (7 ft 3 in) ceiling height. Certainly not: with a low slope, the same height feels like a "low ceiling height," whereas with a steeper slope it would be perceived as a generous knee wall.

Aren’t those actually two full stories after all? That’s strikingly accurate.

According to §2 (4) of the Lower Saxony Building Code, an attic counts as a full floor if it has a clear height of 2.20m (7.2 feet) over more than two-thirds of the floor area of the story below.
This is how I calculated:
9.85 x 9.6 = 94.56 square meters (floor area).
Two-thirds of that = about 63m² (678 square feet).
63m² / 9.85m (32.3 feet) = 6.4m (21 feet) -> meaning 6.4m (21 feet) may be above 2.20m (7.2 feet) height (9.6m (31.5 feet) - 6.4m (21 feet) = 3.2m (10.5 feet) must be below if the slope descends towards the north).
With a 5° pitch and 2.20m (7.2 feet) height at 3.20m (10.5 feet) building depth, I have on one side a wall height of 1.955m (6.4 feet) and on the opposite side 2.78m (9.1 feet). I assumed a wall thickness of 40cm (16 inches).
I’m unsure whether the wall thickness counts as below 2.20m (7.2 feet) – I just assumed yes.
The 2.20m (7.2 feet) line is drawn in, and with a rough estimate, you can clearly see it does cover about two-thirds of the area. Please feel free to dispute this – I’m no expert. But I would appreciate actual numbers instead of just “looks convincing.”

In our discussion, the house with 140sqm (1507 sq ft) without a basement is roughly estimated as follows:
What do you think about this "rough" estimate? The scope of work description is intended to be very similar to that of the other builder, as they come from the same region and are familiar with each other’s scopes of work. Advantage?
- Solid house – fully brick-faced = 255k
- Plot fully supported with L-shaped retaining walls, approx. 100m (328 ft), installation and materials = 20k
- Paving work = 10k
- Masonry double garage including foundation, etc. = 40k

We will receive the detailed and exact quote shortly.
What do you think about this "rough" estimate? The scope of work is supposed to be very similar to that of the other builder, as they are from the same region and are familiar with each other’s scope of work. Advantage?It depends on the scope of work! Just because the general contractor tells you their scope of work is similar doesn’t necessarily mean it is. The price for the double garage seems realistic.How high are the L-shaped blocks? How many courses? Will the terrain be shaped accordingly, or will you need to fill and compact the soil yourself using a wheelbarrow?
Let’s wait for the scope of work to see!
