Hello dear forum members,

We are planning to build a semi-detached house with the help of an architect. After that, the working plans and individual contracts will follow. We have a floor plan and would like to get some feedback here. The floor plan is partly somewhat unconventional. According to the architect, everything is good and feasible.

Note: The surveyor’s excerpt is aligned to true north, but unfortunately, the floor plans do not show the cardinal directions. The open-plan kitchen and living area face exactly southwest.

House design
Who designed it:
- Architect according to our wishes

What do you particularly like? Why? large glass front facing southwest on the ground floor, orientation and size of children’s rooms
What do you not like? Why? layout of the bathrooms on the upper floor, uncertain regarding number and size of windows
Price estimate according to architect/planner: 410,000 including basement and ancillary construction costs
Personal price limit for the house, including fittings: 435,000
Preferred heating system: district heating mandated

If you had to give up something, which details / features
- you cannot do without: 2 shower options, cooking island, laundry chute

Why is the design the way it is now?
What wishes were implemented by the architect?
What makes it particularly good or bad in your opinion?
It turned out interesting, we’re just not sure how practical it is.

What is the most important / fundamental question about the floor plan in 130 characters?
Is the floor plan sensible? We usually only see standard layouts for semi-detached houses. Is the straight staircase too steep? Are the construction costs realistic?

Thank you very much for your feedback!

How long is the straight staircase?
What is the lounge intended for?
Why are there two bathrooms on the upper floor and none on the attic floor?
What is the multipurpose area, which is almost entirely below the 2 meter (6 ft 7 in) height line, supposed to be used for?

True, you can’t tell from the resolution. The staircase is 3.75 m long (12.3 ft).
The lounge is intended as a small retreat space—for reading a book, taking a nap, or similar.
A bathroom in the attic created a conflict with the sloping roof. There was consideration to design a bathroom accessible from the bedroom. However, this would limit use for everyone else.
In the workspace, a countertop runs along the entire length. It serves as an office, craft, and sewing area. There was a nice example of this online.

Working area in the attic: laptop, plant, books; three chairs, view into the bedroom.

The staircase is too short. One more step wouldn’t be a luxury. I would consider a different staircase design. Somehow it divides the house into two parts. The first part feels a bit like leftover space to me.

The workspace is nice, but definitely not 5 meters (16 feet) long. Also, cabinets and storage space are missing. To me, it seems more like a makeshift solution.
The shower should fit upstairs, though. Instead of a walk-in closet, you could have a small bathroom.
I find the lounge very small, and the kitchen could use a bit more space. Especially since you have your quiet retreat upstairs.
I find the floor plan unusual, but unfortunately not necessarily for the better. You don’t want something standard, which I appreciate, but this isn’t really working either. What is the purpose of the second room in the attic?

Hmm, I think the workspace in the attic is fine for parents' hobbies, like crafting, setting up PCs, the sewing machine, etc. The kids should stay downstairs since they already have their own floor. I would also try to fit a shower bathroom upstairs because I don’t want to have to go down the stairs if I need to use the bathroom at night.

The biggest drawback I see is actually in the living room — don’t you have a TV? Where would it go? There is also basically no storage space there. Or do you not have any furniture? That can happen too.
