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

Check with experts whether building on filled ground is possible – then a catalog house could still work.
Or if the area of the foundation slab needs to be replaced, or if everything must be removed.
The floor plan should follow the slope of the land. The fewer earthworks, the cheaper.
Don’t dismiss a basement immediately. A finished basement is fully usable living space.
If the zoning plan allows it:
Basement level: living area
Ground floor: children’s rooms + utility room + technical room
Upper floor: parents
Same square meters, smaller footprint

Based on this, or at the same time, find a company that can build a simple house with four straight walls and a gable roof.
Consider carefully if you really want to build. You will not only forgo golden faucets, but many small things that are considered must-haves nowadays.
You might want to contact Nordlys. He could maybe help you find where to save money without compromising quality.


I’m open to criticism... but some here...

As I said, if you have to budget €300,000 (about $330,000), I am now a bit wiser. As I mentioned, I have contact with a construction engineer who said this house can be built for €210,000 (about $230,000). If someone says I’m naive, fine, but you assume they know what they’re talking about, right?

I never said that you are naive.
The prices he quoted are hardly achieved here by anyone, especially not for turnkey construction and certainly not on a slope.

Do you want to build like in the link?

Does your building permit / planning permission allow this?

Location aside: you have a sloped plot. This offers great opportunities, but they are generally not standard and therefore more expensive than average.

Do you have any examples or photos that I can use as a reference?

We do find city villas quite elegant! But what you want and what can actually be realized are two different things. I would also consider a split-level house, that is, built into the slope. You can make everything look nice. However, it doesn’t help to get stuck on something upfront that can’t be achieved in the end. That’s why the approach here, using the forum, is to get more opinions and ideas.

Personally, I don’t like it when someone is repeatedly made fun of here, even if it’s justified, when they have already openly admitted their mistake. As I said, those who criticize the hardest have probably done other silly things themselves. Nobody is perfect!

Find out what can be done with the pile of soil. I would be hesitant to build on it. Just as an example, our garage driveway is constructed and compacted in layers using 0/32 crushed stone up to a depth of 1.2 m (4 feet). The paving will only be done next year because some areas can settle by up to 5 cm (2 inches).

A city villa is a classic slab-on-grade house built on flat terrain.
What exactly do you like about the house? Maybe some aspects can be adapted.

Yes, you can already see that the soil has settled quite a bit. It has been there for about a month now.

What we liked about the house, apart from the appearance, was the few sloped roof sections.
