I am posting the floor plan here for the first time – the basis is the Edition 425 Wohnidee from Viebrockhaus in the 1.5-story version – we have redesigned it with a gable entrance, because otherwise the entrance would be directly from the south, where we want to have the living/dining area + terrace.
The questions from the posted thread are, in my view, largely irrelevant since the basic volume is already fixed and only the interior floor plan is up for discussion, or marginal changes to the volume would be unproblematic. Still, here are the relevant details:
Development plan/restrictions Size of the plot – 743 m² Slope – no Floor area ratio 0.3 Number of parking spaces – double garage 6x6 + storage room Number of stories – single-story (eaves height max. 4m = rafter cut point) Roof shape – gable roof Orientation – S - SE Maximum heights/limits: eaves height (rafter cut point 4m), gable height 9m further requirements
Owners’ requirements Number of people, ages – 4 – 2 adults 38, 2 children 5 + 8 Room requirements on ground floor, upper floor: GF = kitchen, utility room, guest room, living/dining, guest WC, garage, storage room Office: home office Open kitchen, kitchen island – kitchen island: no; open: separable by an internal sliding door Fireplace – no Music/stereo wall – optional Balcony, roof terrace – no Garage, carport – yes, double garage + storage room, total 6x9 Usable garden, greenhouse – no Further wishes/special features/daily routine – separate parents’ area on the upper floor, second bathroom in the attic, guest WC without shower, pantry in kitchen; utility room for dryer + washing machine, remaining technology in basement; bus system, photovoltaic system + storage, central controlled indoor ventilation, underfloor heating (all in the basement)
House design What is disliked? – layout of the upper floor, especially bathrooms + layout of parents’ area; utility room could be somewhat larger Favored heating technology: air/water heat pump with photovoltaic (approx. 6.7 kWp + storage, approx. 8 kW), 300l hot water storage
