Hello everyone,

For several months now, we have proudly owned a plot with an existing building and plan to start construction next year.
After several rounds with architects and general contractors (GCs), two are still in the running, and we want to decide by next month at the latest who we will build with.
The design mostly incorporates my sketches, and the more serious it gets, the more uncertain I feel about how coherent the planning is.

I have been following the forum for some time and look forward to your honest feedback, hoping not to be torn apart too harshly in the "lion’s den."

P.S. The site plan is not 100% accurate since we slightly enlarged the ground floor in the last round.

Thank you very much for your feedback and suggestions...

We still find the window situation a bit chaotic, and the many different sizes make it look quite busy. We will definitely want to make some improvements there.

Regarding the kitchen/living room swap, my wife is very keen on having the kitchen at the top of the plan, facing the street. One idea we are now reconsidering is moving the study to the basement to create more space on the ground floor. But I agree with you, it would have a certain charm to stand at the front door and then look through the kitchen into the garden. The short distance between the kitchen and the garage would be another advantage. The downside would be losing the freestanding kitchen island of 3 meters (10 feet) in width, given a total width of 4.31 meters (14 feet).

I can’t say much about the floor plan because others are more qualified, but I find the exterior views – southeast and southwest – somewhat unharmonious in places (I can’t enlarge the floor plan to read everything).
May I ask what budget you allocated for the windows? Especially the 6-meter (20-foot) window?
We ourselves are currently waiting for the final cost calculation, so we cannot give you exact figures at this time.

I think the access to the open living area hasn’t been given any attention in the plan. It really deserves more.
Indeed, we haven’t given much thought to the impression of the open living area. Our top priority was not to waste too much space on it. To enhance the area, we are now considering a left-turning open concrete staircase with a folded structure design and a railing for the children’s safety.

The 7.19 meters (24 feet) length of the living room should be thoroughly furnished to see that it’s not as spacious as it appears.

The living room couch and dining area roughly represent the real furniture arrangement. We are missing a footstool measuring 90cm x 90cm (35 inches x 35 inches).

For the shower on the upper floor, I would definitely only build the wall halfway high and then add a glass panel. Otherwise, it will be very dark there. Apart from that, I find the corner bathroom really interesting.

Great idea with the half-height wall and glass panel; we will definitely want to discuss this at our next meeting with our general contractor.

Changing the shower access in the bathroom.
What exactly do you mean by that?

I would have placed the living room upstairs because, purely from a floor plan perspective, the kitchen is better positioned next to the dining area. For me, the living room should be somewhat more separated than the kitchen. Additionally, the kitchen would then be directly next to the terrace, which means less walking distance in summer.

The interior walls are supposed to be solid masonry and are mostly built to the correct dimensions, but what exactly should I expect from the 40cm (16 inches) exterior wall?
I find the kitchen bay window less appealing than the window arrangement, which should be fairly easy to fix.

Shower exit not past the window, but along the interior wall, so no one can see in,

We were told that to meet the KfW55 standard, 40 cm (16 inches) aerated concrete blocks are necessary, combined with a ventilation system and an air-to-water heat pump. The interior walls are planned to be built with sand-lime brick.

From the outside, it looks more like a compromise. The extension would be great for the kitchen but is not needed on the upper floor.
