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

...and how many more times are you going to put question marks at the end of sentences where there shouldn’t be any?

How many more times? For us, this is "manageable"!

I just want to raise awareness about this topic. Not everyone can or wants to pay a monthly mortgage installment of €1880 (about $2000) plus €450 (about $480) in additional costs for a house. Because that is exactly the amount you will have to pay every month for the next 22 years in order to be debt-free before retirement. This is precisely what many banks require!

I have just roughly calculated the living area we need and came to 130 sqm (about 1400 sq ft). Whether it will later be your estimated €400,000 (about $425,000) is seen differently by others here as well. We will see in the end who is right, but that’s not the main point. It is better to plan carefully and have a bit left over later than the other way around. And only we know how much equity we still have available, right? Another question mark!

Well, it really depends on what you do with your equity. As long as you don’t include the equity as actual equity in the financing, with 400,000€ you only have a loan-to-value ratio of 90% and no more. No matter how well-filled the account is. If it’s not used and spent before the loan is disbursed, the bank simply doesn’t consider it. It’s that simple.

Thanks for the exclamation mark!

By the way, these numbers were from the end of 2017. When are you starting construction? Early/mid 2019?

Irony or serious?

Where is the irony? – Everyone can see this (except for some zoning plan posters): when it comes to whether the building mass overwhelms the viewer or neighbor, the eaves height and ridge height are enough. The knee wall height only indicates how far below the eaves the ceiling runs inside. That doesn’t affect “third parties” positively or negatively – so why should it concern them? Whether I have 255 cm (100 inches) floor-to-ceiling height on the ground floor and a 125 cm (49 inches) knee wall or 280 cm (110 inches) plus 100 cm (39 inches), the eaves height remains the same and should be my business. If I stay within my eaves height “budget”: so what.
