House design
Who created the plan:
-Synergy Architect + client, 4th draft now
What do you like especially? Why? Guest room and WC + shower, similar construction already now, works (although a bed is drawn, it is a sofa bed), office in the north, guest room size more than sufficient, wardrobe at the entrance, living room bright, washing machine + dryer on upper floor.
What do you not like? Why?
- Utility room is half unusable due to the insertion of the wardrobe (which actually makes sense) and therefore too small, attic must be moved from garage into the thermal envelope in the utility room, indoor unit could stay there. Controlled residential ventilation would also have to go into the utility room. Possible solution: enlarge kitchen to the back and correspondingly extend utility room. But the house then becomes even bigger... Another solution has not been discussed so far.
- Staircase too steep, architect now proposes 17.2/26. That would probably be borderline for tread depth.
- Daylight in the children’s rooms could be little due to window orientation west and about 12.5% window area/room size; might need to be checked in a simulation. Velux would not improve that much, only one dormer and then smaller windows in the gable.
- As the kitchen island is drawn, I do not like it, passage from utility room too narrow. Should be on the other side and sink + window to the left.
- In the bedroom and guest room air conditioning units should still be installed, but that looks impractical with windows and wardrobes.
- Shower on the upper floor under the slant, not necessary. But a minor point.
- Skylight in guest WC not at head height, a bit higher, also a minor detail.
- Bathroom door upstairs should open outwards
- Still missing storage under the stairs
- Wall in the garage not necessary

Price estimate according to architect/planner: n/a
Personal price limit for the house, including equipment: 650k
Preferred heating technology: air heat pump

If you have to do without, on which details/extensions
-you can do without: dressing room
-you cannot do without: office, guest room

Why is the design the way it is now?
Own design based on room requirements and architect’s counter-design further developed

What makes it, in your opinion, particularly good or bad?
Most important points to clarify are utility room + technology and daylight.

Personal price limit for the house, including equipment: 650k

Reconsider the budget. It is a very large house with a garage for a small price. Others are responsible for floor plans.

Utility room is half unusable due to the insertion of the wardrobe (which is actually sensible) and therefore too small

No, the utility room is not usable because of the two doors. What is supposed to go in there? And why a door when the front door is right next to it?

The more I look at it, the more convoluted I find the access to the [Allraum]. For that, the sofa still feels too far away for me. [HAR] is way too small for your multifunction. And the [Allraum] is all too elongated. Here is my suggestion, but only to be seen as a sketch. The stairs would need to be enlarged and mirrored, and the cardboard walls adjusted.

The more I look at it, the more complicated I find the access to the open space. For that, the sofa feels too far away for me. HAR is way too small for your multifunction. And the open space is all too elongated. Here is my suggestion, but only to be seen as a sketch. The staircase would have to be enlarged and mirrored, the drywall walls adjusted.

I completely agree with you. What bothers me most about the initial draft is this uninviting foyer. You come in and go into a dark hole with stairs. The exit lies twisted, narrow, and inconspicuously around the corner. Your sketch is better in comparison. I would rotate and mirror it again until the entrance is on the left side. Possibly then exchange the stairs to more easily access all rooms on the ground floor.

I would rotate and flip it until the entrance is back on the left side.

That's how I started. However, there is only a small space window for the staircase at the top. And this way, chaotic corridors are also avoided upstairs. The staircase on the ground floor was always in the way as well.
