House Design
Who designed it:
- Do-it-Yourself
What do you particularly like? Why? Rotation towards south, living area facing garden
What do you dislike? Why? No sunlight from southeast in living area, but no space alternative found as garden access is more important
Cost estimate according to architect/planner: turnkey offer received over €426,000
Personal price limit for house, including equipment: €480,000
Preferred heating technology: heat pump

If you have to give up, which details/finishes
- Can give up: shower in guest bathroom
- Cannot give up: convertible attic

Why is the design like it is now?
E.g., side entrance because otherwise the hallway would be too narrow. Garage on north side where there is no sun. Bay window for sunlight from different directions since neighboring houses are only 2 m (6 ft 7 in) away. Utility room partly usable as cloakroom if space remains.

What makes it especially good or bad in your opinion? Rotation towards south to get more sunlight. Flexibility.

What is the most important/basic question about the floor plan summarized in 130 characters?
Are there any further helpful tips or ideas? What could be improved? Does it feel coherent? Where is further saving potential?

Interesting project. What I still don’t understand:
Why are you starting the house so far back when the front of the plot would allow for a wider house? Is a 10m (33 feet) setback from the street mandatory?

Unfortunately, the building line only starts where the other houses begin, so this is not possible. The front corner is practically on the building line.

Why are the walls 42cm (17 inches) thick?
With thinner walls, you gain more interior space.
I would go for 36 or 30cm (14 or 12 inches), minimizing them to what is strictly necessary.
Is it possible that the house could be slanted, meaning wider at the front than at the back?

That would worsen the southern sunlight exposure, which you can clearly see in the site plan.

As long as there are no children yet, the children's rooms will probably be used as offices. How far is the attic conversion planned to go? By the way, those are two nice rooms.

On the ground floor... unfortunately, the kitchen won’t be very large, so it definitely makes sense to make use of the space under the stairs as a pantry, otherwise the utility room will become overloaded. Maybe also use the rising space with pull-out drawers and store, for example, the freezer cabinet or similar items in the tallest area.

I would also add another window on the right wall of the living area.

I would also suggest deviating from the rectangular shape here. Maybe not angled right away, as that is usually quite expensive. But at the front, you could go up to about 7m (23 feet) wide, which already makes a difference. Something like this:

A 12m (39 feet) garage edge construction would be quite unusual. Typically, it's a maximum of 9m (30 feet). I find parking two cars one behind the other very impractical anyway. The parking space in front is fine. Why not have two next to each other?
Considering the proximity to the neighbors, I think the sun corner is unnecessary. Instead, plan for large, wide windows and patio doors to bring indirect light into the house.
