Draft of the planner for our single-family house

White clinker bricks are simply disproportionately much more expensive. We like dark gray ones, and if it were only about the appearance, we would also plaster a white stripe about 5m wide on the gable ends. Unfortunately, this is probably not allowed and also contradicts the principle of a low-maintenance facade.

We have now decided on gray-blue clinker bricks and anthracite-colored roof tiles. On the planner's advice, the roof tiles are not glossy/glazed. The window frames will be white. The house has now become about 15 cm larger (north-south) to enlarge the utility room and the hallway in the bedroom. Then there was the question about the roof overhang. We have now chosen 80 cm in the north and 50 cm in the south, because otherwise the roof overhang/roofing over the kitchen would have been only 2.25 m high. It is still quite low, but the geometry of the roof is unfortunately determined by the projecting living room and the single-story structure. The planner advised against a "kink" in the roof at the kitchen roofing area. What we do not like 100% yet are the elevations; some fine-tuning is still necessary here—but according to the planner, this is still possible after submitting the building application. Currently, we are dealing with tiles. We would like to lay wood-look tiles throughout the entire ground floor and upper floor (maybe some variety in the kitchen area, bathroom, and utility room?). I have three questions for you about this: 1) Is this a good idea? Will one get tired of it and eventually wish for plain tiles? 2) Should one rather choose a light or a dark tone for tiles, or what should be considered here? Personally, I like dark because it looks more "honorable"... but dark tiles surely absorb a lot of light in the room and then it is necessary to have white furniture? 3) What price per m² should we set as material cost? We have now seen some for €15 / m², but also some for €40 / m². Both porcelain stoneware, through-colored, same abrasion class and slip resistance. The "expensive" tile mentioned something about an "Ink-Jet" process. Are there really differences here, or is that just the brand? Another topic is bathroom planning on the upper floor. The bathroom is 2.45 m wide and 3.3 m long. The door is on the short side. The planner suggested arranging the bathtub and shower on one side and the toilet and washbasin on the other side. But we had thought about a corner bathtub and have already searched a lot on the internet—unfortunately, we found few layouts that really fit. Does anyone happen to have an idea?

Hello,
regarding the tiles:
on dark tiles you can see every streak and every speck of dirt. In the entrance area, I would definitely choose something else.
I don’t think the wood-look tiles are so bad either, provided they guarantee a certain number of different patterns. This usually comes with significant price differences. That’s why they were out of the running for us.
In addition, there is of course the effect that the wood-look tiles might clash with the wooden cabinets. So if you, for example, combine strongly textured pine with core beech, it certainly looks ugly. That’s why I would always choose as discreet a look as possible for the floor—if you already have furniture. Or you buy high-gloss white furniture—yes, that can also be cool. Well, many roads lead to Rome...
Apart from the variety of patterns, we only noticed price differences with the tile thickness (1.2 cm for the floor was, I think, the minimum) and the finish—meaning straight edges and 90° angles. Under €20/m² was just rubbish. When doing the math, you should not forget the baseboard—that adds a nice chunk to the price.
Slip resistance and abrasion should also be mentioned.

[*]Abrasion class 1 – very low wear (e.g., for bedrooms and bathrooms)
[*]Abrasion class 2 – low wear (e.g., for living and dining rooms)
[*]Abrasion class 3 – medium wear (for heavily used living areas)
[*]Abrasion class 4 – high wear (heavily loaded areas such as store floors)
[*]Abrasion class 5 – very high wear (commercial use in shops and halls)

In the bathroom, we paid attention to high slip resistance, since you move around there with wet feet. Otherwise, it was not that important to us.

@kaho has already said everything about the tiles, I can only confirm these statements and add that with wood-look tiles a seemingly good wood appearance only occurs at over 70. Below these prices, you can see the fake appearance, which may, however, be intentional. Regarding the bathroom: Corner bathtubs take away space from narrow bathrooms, so they are not really suitable for that. The neat standard arrangement always looks elegant.

Thank you for the answers. We will take another look – maybe we’ll prefer more unobtrusive tiles after all.

One more question came up: according to the planner's calculations, we have about 70 m² of usable space in the attic (~29 m² living area). The planner recommended placing the airtightness layer in the wooden beam ceiling between the attic and the loft because it is simpler and therefore cheaper. Furthermore, there would be 124 m³ less volume to heat. However, he also said that a subsequent conversion would not be easily possible or at least not quite simple. We are now torn. We definitely do not need the space as living area at the moment, and we do not know if/why we would ever need it later, but we would also find it a pity to let the whole thing "decline." Has anyone of you also faced this choice and can still remember the additional costs for the converted attic – roughly, of course. Surely, you would have to calculate two roof windows, radiators, etc. as well.

Our finished attic (60m2 floor area) cost about 20,000 euros in total. Insulation, flooring, knee wall cupboards, stairs (not pull-down stairs), 2 regular windows (without shutters), 1 skylight, 2 doors, heating (however, no underfloor heating) all included.

By the way, one room will be a playroom for the kids and one room will be a basement substitute. In between, a nice hallway with a skylight and possibly a small retreat area for me.
