House Design
Planner: synergy between architect and client, now 4th draft
What do you particularly like? Why? Guest room and WC + shower, similar existing layout already working (although a bed is drawn, it is actually a sofa bed), office on the north side, guest room size more than sufficient, wardrobe by the entrance, living room bright, washing machine + dryer upstairs.
What don’t you like? Why?
- Utility room is half unusable due to wardrobe protrusion (which is actually sensible) so it is too small. Attic storage needs to be moved from the garage into the thermal envelope inside the utility room, indoor unit could stay there. The mechanical ventilation system would also need to be installed in the utility room. Possible solution: enlarge kitchen to the rear and expand utility room accordingly. This would make the house larger though. No other solutions discussed yet.
- Stairs are too steep; architect now proposes a rise/run of 17.2cm/26cm (6.8"/10.2"), which may be borderline regarding comfortable step depth.
- Daylight in children’s rooms might be low due to west-facing windows and roughly 12.5% window-to-floor area ratio; simulation might be needed. Skylights wouldn’t significantly improve this; only a dormer and smaller gable windows would.
- As drawn, the kitchen island layout is not suitable for me; passage from utility room too narrow, should be moved to the opposite side, with sink and window to the left.
- Air conditioning would still be needed in the bedroom and children’s rooms, but with the current window and furniture arrangement this looks impractical.
- Shower upstairs located under sloped ceiling, not necessary but a minor point.
- Skylight in guest WC is not at head height, should be slightly higher, also a minor detail.
- Bathroom door upstairs should open outwards.
- Storage under the stairs is still missing.
- Partition wall in garage is unnecessary.

Cost estimate from architect/planner: unknown
Personal price limit for house including fixtures: 650,000
Preferred heating technology: air-source heat pump

If you must give up something, which features or extensions
- Can you give up: walk-in closet
- Cannot give up: office, guest room

Why is the design like it is now?
Own design developed based on space requirements plus architect’s counter proposal

What do you consider especially good or problematic?
Main issues to resolve are utility room + technical space and daylight.

Floor plan ground floor with kitchen, living/dining, garage, terrace and garden.

Floor plan upper floor: bedroom, bathroom, hallway, dressing room, child 1, child 2, office.

Two house views: northwest with gable roof; northeast with garage and modern facade.

Two house views: southeast and southwest with garden, trees and windows.

Attic: storage 26.92 m² (289 sq ft), stairs, two roof windows, continuous roof edge.

Detailed plan of street layout with red roadway, sidewalks, parking spaces and green areas.

Are the 9.50 meters (31 feet) ridge height in the architect’s plan already maximized? Is there a cross-section available for it?

I think the original poster should first finalize the attic issue, also considering the budget, before having new plans made.
Placing some of the technical equipment in the garage seems, in my opinion, rather unwise. Which equipment exactly and what do you expect to achieve with that? Is the space intended to be included within the thermal envelope?

The issues of technical equipment and attic have been discussed extensively. Now we are just waiting for a response from the architect, which might take some time.

No cross-sections yet, sorry, maybe in the next version.
No cost breakdown either, so no idea what we’re facing financially.

344 depth in the kitchen is tight,
You can feel free to suggest to the original poster to build larger.

Well, the house isn’t that huge after all. It’s a one-and-a-half-story building, and a total width of 12m (39 feet) isn’t unrealistically large given today’s wall thicknesses. Has it been stated anywhere how many square meters it is in total according to DIN standards?

Do you at least know the roof pitch, or has it been mentioned somewhere already?

At the earliest, this evening.
