Hello,
Passive house according to the definition of the iPHA. Mainly achieved through insulation, therefore not so much additional technology.
Then it is not a passive house but a low-energy house; that is already a significant difference!
It is quite interesting what can all be sold under the magic word "PH":
the architect meant that one should rather pay attention to the cost-benefit ratio
That at least is a wise statement.
Well, then I’ll roughly estimate what it would cost here in the Rhineland, built solidly:
House 9.50 x 11.50 m as a KfW 70 efficiency house including living cellar: TEUR 283
Lift system: TEUR 6
Masonry garage basement/ground floor: TEUR 18
Rooftop towing FG: TEUR 5 - X, depending on execution
Controlled ventilation with heat recovery: TEUR 12 - 16, depending on provider
=> up to here including architecture and structural engineering costs
Typical ancillary construction costs: TEUR 35-40
I can’t say anything about additional foundation costs, as I don’t know the exact slope location or soil condition. But I would at least use the architect’s values
Painting and flooring in EL: TEUR 10
Outdoor facilities in EL: TEUR 10
Reserves for extras: TEUR 10
Floor plans attached.
Thanks.
Who came up with the sensible idea to locate the pantry under the ground floor bathroom? I would swap that with the small utility room on the ground floor regarding the pipe routing.
PS: what do you need three-phase power worth TEUR 12 for?
Rhenish greetings
