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

I already wrote that it includes the plot! I have the documents! I just don’t want to post them because your name can be seen there.

When am I supposed to laugh? At you for believing the price or at the engineer for being so stupid?

How much did your plot of land cost? Do you think that with the difference minus additional construction costs you can get a house? What would the price per square meter/dollar for the house be then? 900€

Sometimes you make a typo.
With such a huge amount, it’s reasonable to ask for clarification.
Take a photo of the offer and redact the name digitally. Then please upload it as a JPG.

With such an insane amount, it’s worth double-checking.

Here’s proof so you can slowly start to believe it! The house was offered as a prefab house in timber panel construction:

Cost breakdown according to DIN276 including land, development, and shell construction in a table


Cost statement by trade for shell construction and foundation of a building project


Cost overview of construction expenses with tables and subtotals for building project


Cost table additional charges for exterior work including landscaping and cost overview

If I didn’t know that you and he are serious about this, it would be both funny and sad at the same time. After seeing the numbers, I can only say that he would have sent you into personal bankruptcy without hesitation. You would have been short by at least €150,000–200,000 (about $160,000–215,000) for the house. That’s absolutely unacceptable on a personal level. It’s good that you registered here.

But since I’ve been talking endlessly and you’re still talking about hiring individual trades and an engineer, this is really getting annoying. Listen to the people here who have experience and cut off all contact with that engineer. Have a house built by a general contractor (GC).

Which company does the kit come from?
Danwood quotes three times the price for an insulated ground slab.
Just the additional work from the tiler cost us about the same.
I would have the offer checked!
We’re not all-knowing either.
But for general understanding: Danwood and Scanhaus Marlow are budget builders, still acceptable if you don’t choose many extras.
You also have to add the ground slab and transport costs with them.
As well as additional construction costs like landscaping.
Please compare the prices now.
Your price sounds like a garden shed fitted with single-family house technology.

Ah... could it be that it’s a shell house with a technology package? Then the tradespeople’s work is still missing. That would make sense!!!!
