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

Sounds okay. Kitchen + upgrades +50k. Total at 375k – I could imagine that if you don’t go overboard.
Then we’ve met halfway :-p. So with everything included—fence, lawn, shrubs—it almost reached the stated limit.

Okay, then it should be fine. I’m completely unfamiliar with this, just asked based on a gut feeling. With a 2.2 m (7 ft 3 in) raw construction height, most people can comfortably stand inside in the end.

@Frank73

I think it’s not a disadvantage if the two know each other.
Earthworks are still missing.
Depending on the trade, it can still cost less than 400,000 euros.

The question is whether I prefer a steeper slope of the gable roof and therefore cannot stand at the knee wall, but at least the room reaches a height of 2.40 m (7 ft 10 in). Or if I accept a "box room" with ceiling heights from 2 m up to 2.20 m (6 ft 7 in to 7 ft 3 in) over almost the entire space. You can stand in that, but it’s not exactly pleasant. I have even considered placing technical installations in the 2 m (6 ft 7 in) areas above. Then the bedroom would have to be downstairs...

How does it work with a split-level design if I dig one half into the ground (considering the 1.40 m (4 ft 7 in) limit) and then have a shed roof above? Could I then sort of cheat and have two full floors?

Fascinating!

It depends on the scope of work! Just because the general contractor (GC) tells you that his scope of work is similar doesn’t mean it actually is. The price for the double garage is realistic.

How high are the L-blocks? How many courses? Will the terrain be shaped as well, or will you need to fill and compact it yourself with a wheelbarrow?

Let’s wait for the scope of work!

The L-blocks would be installed on three sides to enclose the property. The builder also mentioned that he would place another row of L-blocks beneath the building, positioned crosswise to stabilize the structure. This way, you could access a second level (the garden) from the terrace with just a few steps, which would then gently slope down towards the rear. Therefore, at the lowest point, you wouldn’t need 1.8 m (6 feet) or 2 m (6.5 feet) tall L-blocks, but smaller sizes, which would of course significantly affect the price.

The scope of work from the other builder was already quite good, as has been commented here. I’m hoping that now, when preparing the offer, he is aware of what his competitor is proposing.

We won’t be visiting Town & Country anymore. So far, I have a good feeling about these two. The better one will get the job...

Yes, it doesn't have to be more than necessary. We're also considering whether it really needs to be an attic conversion. Actually, we wanted to settle at a maximum of 350,000 euros (about $375,000)!

Equivalence )
"You basically get the same thing from us, we all know each other in the industry" is probably one of the most common sales clichés. So be careful who you commit to for the long term.

Avoiding full stories )
This is not exactly my area of expertise, but I would never advise trying to creep exactly to such a limit down to the square centimeter.
