Hello everyone,
After browsing the forum a bit and mostly reading along, I would like to share our building project and ask for your opinions on our floor plan idea and the roughly calculated costs so far. The house will have the following key features:
We have put together the following floor plan, which best matches our current ideas:


What do you think? Some users have mentioned that it is not ideal for the staircase to be right next to the front door. I can understand the argument about dirt being tracked in. However, this layout seems to us to be the best option in terms of minimizing space used by the entrance area and stairwell. Increasing the house’s external dimensions would also significantly increase costs.
Regarding the guest room, we prefer to have it on the ground floor. We are also thinking ahead to when we get older and would then have a potential bedroom on the ground floor. That is also why there is an additional shower in the guest bathroom on the ground floor.
We have not given much thought to the windows yet. The windows shown on the floor plan are therefore not final, and we would appreciate any ideas or suggestions.
Concerning the overall costs, we would like your opinion on how realistic the following breakdown is:
205,000 € house price (= 1,450 €/sqm (135 USD/sq ft) – offer already received)
30,000 € additional building costs
15,000 € specification buffer + extras
10,000 € materials for outdoor facilities, mostly done by ourselves
-------
260,000 € total costs excluding land costs
Do you see any potential to reduce these costs? It all seems a bit high to us overall. We would also be grateful for any further suggestions.

After browsing the forum a bit and mostly reading along, I would like to share our building project and ask for your opinions on our floor plan idea and the roughly calculated costs so far. The house will have the following key features:
- Solid construction detached single-family house with approximately 142 sqm (1,528 sq ft) of living space and a gable roof
- No bay windows/balconies etc.
- Building location: Saxony/Chemnitz
- A "normal single-family house" for 4 people plus a guest/office room
- Slightly sloping plot from north to south – about 700 sqm (7,535 sq ft) in size

(Staircase faces north)
In the floor plans, the living area has now been reduced to 132 sqm (1,420 sq ft), which should also help lower the overall costs slightly. What do you think of the layouts? We are still not quite satisfied with the arrangement of the sanitary fixtures on the top floor. We want a walk-in shower with a built-up base, but as shown in the plans, it blocks a lot of natural light from the washbasins. Do you have any ideas for a different layout?

We also want to use it to store the printer, folders, etc. Originally, we wanted an open-plan kitchen, which would have opened up the entire ground floor. However, we changed our minds because of cooking odors. Additionally, we need the extra wall for a large bookshelf.

I would also swap the shower and washbasins as Mycraft suggests. Otherwise, the design seems functional and fine to me as a layperson. If you swap them, the shower’s side wall must not be built masonry either, because otherwise it would also lack natural light. Additionally, the door area could become very tight.

Somehow, I find the three fixtures quite cramped along the wall.
Maybe you could move the bathtub to the exterior wall, shift the toilet to the 2-meter (6.5 feet) limit, and place the shower next to the toilet (relocating the door)?
