Hello,
after I had already posted our project once before, but it suddenly disappeared from the forum (probably due to my own mistakes), I would now like to give it another try after some revisions.

Here is the list:
Development Plan / Restrictions
Plot size: about 22 x 22 m (a few cm less), approximately 500 m² (5,382 sq ft)
Slope: minimal, negligible
Site coverage ratio: - (no development plan)
Floor area ratio: - (no development plan)
Building envelope, building line and boundary: §34 (3 m (10 ft) from neighbors)
Edge development: garage
Number of parking spaces: 1-2
Number of floors: 2 full stories
Roof style: hipped roof
Architectural style: urban villa
Number of residents, ages: 2 adults, 1 child + 1 more planned
Space requirements, ground floor and upper floor:
Office: family use – as playroom/guest room
Guests per year: few (1-2)
Open or closed architecture: rather open
Open kitchen
Number of dining seats: 4
Fireplace: no
Garage planned size: 3.75 x 8 m (12 x 26 ft)
Garden with small vegetable patch + playground/swing for children, otherwise designed to be low maintenance
Additional wishes/particulars/daily routine, also reasons why certain things should or should not be included: We want a spacious, open-concept living, dining, and kitchen area on the ground floor; otherwise, a small guest/playroom on the ground floor to protect the living room from a flood of toys. My husband insists on a door from the garage to the utility/technical room. The laundry room and technical room should be separated spaces.

House Design
Who created the plans: a mix of our own design, a “ready-made” floor plan from the internet, and drawings from our general contractor
What do we particularly like? Why?: The ground floor layout feels like an ideal compromise between our wishes and what seems feasible. The staircase is “open” in the living room, which might not be ideal but we accepted it to gain space in the open living area and not sacrifice it to the corridor. We really like the half-turn staircase with landing. Small hallway upstairs.
What do we dislike? Why?: Too few windows upstairs, especially in the bedrooms (children’s room/master bedroom). The upstairs bathroom is narrow and long – unsure if it can be improved; maybe orient it toward the south and adjust the utility room accordingly? Or does it only feel narrow (currently we have only a tiny bathroom, so maybe we lack the imagination for its actual size). Exterior appearance (windows) not attractive/asymmetrical.
Cost estimate according to architect/planner: about 320,000 including garage (possibly more, as the garage was initially planned smaller)
Personal budget limit for the house, including equipment: 400,000
Preferred heating system: gas + solar thermal system

Anything else to mention? The plot was subdivided from the western adjoining property, which belongs to my husband’s grandmother (90 years old). The street to the south is an unpaved road with a slight slope. All utilities (except water/sewer) are available only on the paved street to the west. We want to access the property via the dirt road and not through my grandmother-in-law’s property, even if the path is longer and thus more expensive.

Initially, we had a square floor plan, but not everything fit perfectly. That’s why we ended up with this rectangular design. Personally, I would prefer to rotate the house (open living area facing south, entrance on the east side) and place it closer to the northern building line. However, then the garage could no longer be directly attached to the house (which my husband really wants). Also, the garden/terrace would be fully exposed in that position.
The parking space in front of the garage is probably too short for any car bigger than a Smart. In any case, we don’t want a fence or gate in front of the garage but want to keep the space paved and open for easy access by car.

Okay, I think I have everything. I’m now very curious to see how severely the floor plan will be criticized ;-)

Much, much better.
I believe 5 meters (16.4 feet) in front of a garage is a legal requirement everywhere, right?
Now, I would only change the bathroom door along with the cloakroom, but it’s not absolutely necessary. Both options have their advantages, but I would shift the door to the open-plan living area a bit further toward the top of the plan. Possibly also add a dividing wall (short wall) between the staircase and the living room to ensure a bit more privacy 🙂

I didn’t like the original design at all,

Inside the house, the multi-utility unit requires space, but not on an outside wall. Ours is not even located on an exterior wall.

We just sat down again and reviewed how to incorporate the advice, while also positioning the main entrance facing south. It might be a bit difficult to see, but I hope it’s clear enough.
In this scenario, the house would be located at the very north edge (3m (10 feet) setback), the open-plan living area facing south, and the garage attached to the east side of the house as a boundary construction.
What do you think?

Overall, of course, it works like this!

Please try furnishing the living-dining room and the kitchen. Then we can see if the recess for the wardrobe works and if the entrance to the open-plan area needs to be positioned so far up. This creates a rather long, narrow, and dark corridor. However, I don’t find the slanted walls in the bathroom and guest room very appealing. But that could be done differently as well.

Yes, the slanted walls in the bathroom and guest room were definitely a mistake! Thanks for pointing that out!
I have now furnished it to scale with the furniture we have. Whether they will actually end up where they are now is, of course, uncertain. But everything would fit (at least I would say so).
We don’t have a concrete plan for the kitchen yet. We would probably arrange it in a classic L-shape and then put a counter (just for sitting/working, not a kitchen island) as a visual separation between the kitchen and dining/living area. But as mentioned, nothing specific has been decided yet.
We would definitely prefer the solution of placing the entrance to the south with this orientation. And if that means the open-plan area loses 2–3 sqm (22–32 sq ft), that wouldn’t bother us much.

Thank you very much for your input! We really need it and appreciate it a lot!

An HTR with a width of 1.5 m (5 feet) is far too narrow and overall too small. You might be able to fit the equipment in somehow, but you also need space to install everything and eventually perform maintenance or repairs. What exactly does the abbreviation HA in HTR stand for?
