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
  • Plot size: 722sqm (7,770 sqft)
  • Slope: Yes (southwest)
  • Site coverage ratio: 0.3
  • Floor area ratio: 0.8
  • Building window, building line and boundary: -
  • Edge development: No (only carport)
  • Number of parking spaces: 1-2 (in front of the garage and next to the house)
  • Number of storeys: 1.5
  • Roof style: No restrictions
  • Architectural style: No restrictions
  • Orientation: No restrictions
  • Maximum heights / limits: 3m (10 ft) distance to neighbor

Owner’s Requirements
  • Style, roof type, building type: Urban villa, hipped roof
  • Basement, storeys: No basement, 1.5 storeys
  • Number of occupants: 4 (ages: 44, 45, 16, 6 years)
  • Space requirements on ground and upper floor: Upstairs minimum bedroom 11sqm (118 sqft), walk-in closet 8sqm (86 sqft), 2 children’s rooms 12sqm (129 sqft) each, bathroom 13sqm (140 sqft)
  • Office: Family use or home office?: Not needed
  • Guest overnight stays per year: Rare
  • Open or closed architecture: Open downstairs, rather closed upstairs
  • Conservative or modern design: Modern
  • Open kitchen, kitchen island: Open kitchen with island
  • Number of dining seats: Minimum 6, possibility for a large dining table (big family)
  • Fireplace: No
  • Music / stereo wall: No
  • Balcony, roof terrace: If possible, a partially covered terrace
  • Garage, carport: Preferably a double garage
  • Utility garden, greenhouse: Yes
  • Other: Storage space necessary, as no basement

House Design
  • Who designed the plan: Currently from the forum
  • What do you like most? Why? Great layout on the ground floor, still open upstairs
  • What do you not like? Why?: The upper floor layout still fits 3 children, which we don’t need
  • Estimated price by architect/planner: We thought, excluding land, max $250,000 - realistic?
  • Personal price limit for house, including fittings: €250,000
  • Preferred heating system: We are open!

If you have to give up something, which details or features
  • You can give up: Walk-in closet, double garage
  • You cannot give up: Large bathroom

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

Hey everyone. Mocking the original poster doesn’t help now! Sure, they were a bit naive, but at least they signed up here… so that’s something!

What’s important now is to find out what’s still possible. A quote for the earthworks is needed. The remaining budget either has to be increased or the house design scaled down – whichever way it goes.

With two children, a bit of security is also necessary. In the worst case, the plot might have to be sold again. But we don’t have to assume the worst right away…

The planned floor plan obviously won’t work because of the sloped site.

What’s important now is to figure out what’s still possible. An offer for the earthworks needs to be obtained. The remaining budget must either be increased or the house design scaled back – in whichever direction.

The planned floor plan won’t work at all because of the sloping site.

You’re right, of course, but the original poster must realize that with a budget of 250,000€ for that sloped plot, there won’t be a 120 sqm (1,292 sq ft) single-family house. Honestly, we’re talking about at least a figure starting with 300,000€ and possibly still no garage.

I wonder how naïve someone can be to buy a plot of land without at least getting a general idea beforehand of what to expect during the construction process.

That’s not unusual. It was the same for us. But we accepted that the slope added roughly €100,000 (about $110,000).

The basement wasn’t planned, and just leveling the slope will cost at least €30,000 (about $33,000).

For us, a final figure is only just beginning to emerge now. We moved in February.

You can get a price for the foundation slab on level ground plus the house itself; as soon as there are deviations like a slope, demolition, or inner-city factors (road closures, relocating streetlights, etc.), additional uncertainties arise that construction companies cannot precisely specify in advance.

You just have to work with a buffer.

@ TE
Check with professionals whether building on the filled ground is possible – then a catalog house could still work. Otherwise, determine if the foundation slab needs to be replaced or if everything has to be removed.
The floor plan depends on the slope. The less earthwork required, the cheaper it will be.
Don’t dismiss the basement right away. A living basement offers fully usable living space.
If the zoning plan allows:
Basement: living area
Ground floor: children’s rooms + utility room + technical room
Top floor: parents’ bedrooms
Same square meters, smaller footprint.

Based on this or simultaneously, find a company that can build a simple house with four straight walls and a gable roof.
Consider carefully whether you really want to build. You will be giving up not only golden faucets but also many small features that are now considered must-haves.
