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

Where do you see that?

Roof shape: No restrictions

On a slab foundation – slightly into the slope on the north side (bottom of the plan), built up on the south side. Whether that’s possible, I don’t know.

The nearly square shape works well for the pitched roof upper floor option; for the “entrance-basement” variant, in my opinion, a more elongated shape with a ridge line running into the slope is better suited. So first we need facts here to give these considerations a proper foundation.

Oh, how embarrassing... I was mistaken! Please disregard the part about gable roofs!!!

Oh, you think so? I thought he wanted exactly that.

As I said, we are open to everything. I have learned that you should base your decisions on the building site or plot.

Well... here it says:

Yes, I also don’t understand why someone couldn’t accept a gable roof house with knee walls.
I can accept that. Nowhere did I say that I don’t want that.

Or a shed roof, for which a slope can almost be an invitation.

The problem nowadays is that people don’t accept a plot with its natural terrain as a gift and design something beautiful on it; instead, they have a fixed idea of a house design and then impose it on their plot like a mortgage.

I’m afraid I have to agree with you! Of course, you look at houses you like beforehand, but adapting the design to the plot is the sensible approach – and that’s what we want to do!

I missed it because I was only using my phone:

The zoning plan legend only allows gable roofs.

And here I want to advise Franky again:
1. Visit the plot, 2. read the zoning plan (building permit conditions / planning permission), 3. consider whether you can accept the zoning plan’s requirements. If yes, then calculate (possibly with a soil survey and/or architect) how much earthwork will be needed, 4. buy the plot.

After that, do not plan or favor what is not allowed.

This discussion is more or less pointless.
And without criticizing Katja’s design: there will be another design that fits a sloped plot as well.

I just read: the plot is already purchased...
So reconsider your requirements for your dream house and then post a section view including a photo and site plan of the plot.
If you have owned a plot for two months, you probably have a hand-drawn sketch with plot dimensions and have been moving rectangles around.
So share that, and then we can move forward.

Yes, the plot is already purchased and paid for! Here are the dimensions. Height data (which are on the already uploaded sketch) I only roughly received from a friend who had a leveling instrument on site.
