Hello everyone,

I am new to the forum, but have been following along for a while and have already gathered quite a bit of knowledge.
Attached are the floor plans for the ground floor and upper floor of a single-family house; I know the dimensions do not yet match the floor area ratio, this is just an initial rough sketch that I plan to refine step by step.

Here are the details:
Development Plan / Restrictions
Plot size: 500sqm (5400 sq ft), rear plot
Slope: No
Site coverage ratio: 0.2 → 100sqm (1076 sq ft)
Floor area ratio: 0.3 → 150sqm (1615 sq ft) excluding the bathroom on the upper floor
Building envelope, building line and boundary: only 3m (10 ft) distance to the boundary must be maintained
Edge development
Number of parking spaces: 2
Number of floors: 1.5
Roof type: single-pitch roof
Architectural style: modern
Orientation: southwest
Maximum heights / limits: eaves height max. 4.5m (15 ft)
Additional requirements: old development plan → bathroom upstairs and air space are not included in the floor area ratio; likewise, no sealed surfaces outside the building

Homeowners’ Requirements
Style, roof type, building type: solid construction, rather modern style, large windows
Basement, floors: no basement, 1.5 floors
Number of occupants, age: 2 adults, 1 child (3 planned in total)
Room requirements on ground floor and upper floor: see floor plan
Office: family use or home office? Home office 2-3 days per week
Overnight guests per year: 10
Open or closed architecture: open
Conservative or modern construction: modern
Open kitchen, kitchen island: kitchen directly connected to the dining room via sliding door
Number of dining seats: 6
Fireplace: yes
Music / stereo wall: no
Balcony, roof terrace: no
Garage, carport: double carport → 2 parking spaces as mentioned above
Utility garden, greenhouse: no
Other wishes / special features / daily routine, also reasons why certain things should or should not be included: gallery window from ground floor to upper floor → I know galleries are not very popular here, but we like this very much

House Design
Who planned it: self-designed using building brochures and impressions from friends’ houses as well as show homes

What do you like most? Why? Open living area; the heart of life and a meeting point; central stringer staircase
What do you not like? Why? Corridor size on upper floor; it feels like wasted space as it is really just a hallway leading to the rooms
Estimated cost according to architect/designer: still open
Personal price limit for the house including equipment: 270,000 EUR (without electrical, heating, sanitary, and outdoor facilities) → land already deducted. We are building in northwest Germany
Preferred heating technology: heat pump

If you have to give up, which details or extensions
-can you give up:
-can you not give up: size of the walk-in closet due to the size of Ikea Pax wardrobes, gallery window, shower in the ground floor bathroom, external blinds on the ground floor

Why did the design end up the way it is?
A mix of many examples from various magazines...

What is the most important / fundamental question about the floor plan summarized in 130 characters?
I’m looking forward to your opinions and would appreciate suggestions for improvement J
For now, I have left out the windows, as we are still at the very beginning and it is only about the spatial layout...

Thanks in advance for your help and best regards
Karina

Next time, use graph paper, so you can also keep track of the width of the living room

Yes, and with graph paper, at least you can count the squares when there are no measurements given.

Here I am again, after rereading the original post and checking out the Weberhaus model.

I was confused about the dormer as well as the corner at the house entrance. I see that Weberhaus naturally used it as a covered entrance. You don’t have it because of the floor area ratio restriction, right? However, it will look really odd—rather than enhancing the house, it loses a useful covered entrance.

Then, of course, I understand the calculations involving the storage room and bathroom if @Escroda is confirming them (I’m still a bit skeptical, but if that’s true, then that’s good for you).

But I think it’s pointless to plan based on something like this:

can’t you live without it: the size of the walk-in closet determined by the size of Ikea Pax wardrobes,


When you’re paying around €2000 per square meter (about $210 per square foot) for the house, you don’t plan around a few Pax wardrobes that cost a few hundred euros. As I mentioned above, the rooms all have many flaws that will cause dissatisfaction over time. Kerstin apparently already pointed this out: the bed is inaccessible from one side, and the foot end will probably be too narrow as well.
The closer you look, the dimensions just don’t add up anywhere.

I strongly recommend hiring an architect familiar with the local development plan who knows how to work around or apply for exceptions.
We can continue the discussion then.

Please clarify again, how much exactly?
A dormer as well as an offset shed roof costs more than a gable roof. Add corners and niches and a panoramic window on top.

Edit: I want to correct myself: with this roof orientation, the bed is under the slope, so getting in is possible—except for the narrow aisle. However, the door to the bathroom will not open properly.

Exactly, you will especially bump into the sloped ceiling there, even if the door opens outwards.


Also, windows for Child 2’s room, the bathroom, and partially Child 3’s room will not be feasible due to the sloped gable there.

And a dormer (at least this area would have no slopes) for a gallery. I would recommend planning the gallery, because of the floor area ratio, without the window section under the slope and instead allocate the dormer to other rooms.

Regarding the ground floor as well… the passage line between the carport / utility room / kitchen

the doors will need to be repositioned; otherwise, the interior walls between the utility room/kitchen facing the hallway are rather useless.

I would also like to see some elevations regarding the ground floor extension towards the south and the dormer on the floor above. That doesn’t seem to fit.

Thank you for your feedback.
I have now adjusted the upper floor to match the ground floor and also moved the bathroom door. This time, I used a screenshot instead of the program’s print function so that the measurements are visible.
Unfortunately, I can’t plan a roof with this, but I think professionals will need to handle that anyway.

I’ve also started working on the furnishing... Fire away

Do you think a pitched roof would be better for this plot size and orientation?

Ground floor plan: kitchen, utility room, guest toilet, office, living/dining area with fireplace, cloakroom.

WHAT exactly are you drawing there?

A staircase is one meter (3 feet) wide, 3.80 meters (12.5 feet) long, the entrance hallway is still too narrow, you run into a wall at the utility room door, the sofa overheats from the fireplace’s heat, 40 cm (16 inches) behind the kitchen counter is useless, the fridge is in the way,
where does the gallery view lead?
Wardrobes are ideally 60 cm (24 inches) deep, not 40, where do the kids play? The desks under the sloped ceiling are a headache-inducing setup, a bed is longer than its mattress, I’ve said it twice already: anyone passing the foot of the bed scrapes along the wall, child 3 has about 7 sqm (75 sq ft) under the sloped ceiling... none of this is funny…
Please read your thread again from start to finish before we get stuck in an endless loop here.

I’m sorry, but I haven’t designed many houses yet. Accordingly, I’m also inexperienced with this software. It goes without saying that, for example, not every child’s room actually has a sofa—although I have added one for now. The placement of a bed is also something that can be discussed. At the moment, there is neither a specific bed nor the child to go with it.

The same goes for the refrigerator: it can also be integrated into the kitchen unit—this is by no means fixed yet.

As mentioned in the original post, we are still at the very beginning. This is certainly not an architect’s design. But before I approach a builder or an architect, I would like to have our ideas roughly put on paper.
