Hello everyone,

We have received a plot of land with a small transformer station located at one corner. We have considered various options but haven’t been able to decide on anything yet. This is our first build, so perhaps others might see possibilities or ideas we haven’t thought of.

Development Plan / Restrictions
Plot size
Approx. 21m (69 feet) wide x 30m (98 feet) long – minus transformer station = 570 m² (6135 sq ft)

Slope
Very flat, about 1m (3.3 feet) difference across the entire site.
Road is the highest point, then gently slopes down by -1m (-3.3 feet)

Floor space index
See plan

Floor area ratio
See plan

Building envelope, building line and boundary
Marked on the plan, distances according to Baden-Württemberg state building regulations

Edge development
Non-residential building. To the right side of our plot, the planned residential building with a 3m (10 feet) garage on the neighbor’s boundary is shown.

Number of parking spaces
2 per dwelling unit

Number of stories
2
Max. building height 6.00m (20 feet)

Roof shape
Open, as far as I have read, all roof types are allowed within the corresponding angles

Architectural style
No specification

Orientation
Flexible within the building envelope

Maximum heights / limits
Max. building height 6.00m (20 feet),
Full building height 8.50m (28 feet)
Max. deviation of 0.50m (1.6 feet) allowed for single-family houses

Other notes:
Existing transformer station at the top left corner.
Setback areas marked on our plot.
Currently surrounded by an earth berm that the utility company temporarily placed on our land for renovation – it will be removed.

Client Requirements
Style, roof form, building type
We are quite unsure. A modern townhouse would be great; I like spacious, bright rooms. Flat roofs are less preferred due to waterproofing concerns. Our plan: a single-family home, possibly with two dwelling units for future renting or an immediate granny flat for a home office.

Basement, floors
1 basement planned for hobbies and home office; 2 full floors possible at a max. height of 6.00m (20 feet)?

Number of occupants, ages
4 people (possibly 5 if we’re lucky), 2 adults around 40 years old, 2 children aged 2 and 5 years

Room requirements on ground floor and upper floor
Ground floor: open living room combined with dining area + kitchen + home office or alternative bedroom for older age.
Shower on ground floor.
Office: dedicated home office space, real workspace usage.

Number of guest stays per year
About 5–6

Open or closed architecture
Preferably open, lots of light, I like floor-to-ceiling windows. Still looking for inspiration, ideas from what is common today and what we might be missing.

Modern construction, white bright rooms, lots of natural light, sun, rather bold, extraordinary.
So far, we might be a bit conventional.

Real kitchen, my wife cooks and bakes, with an island and breakfast bar for quick meals or takeaway pizza.

Number of dining seats
6 for daily use, 10 for parties.

Fireplace
Yes, integrated would be sufficient.

Music/Stereo wall
No specific plans at the moment.

Balcony, roof terrace
Balcony planned facing south, intended to serve as sun protection.

Garage, carport
Double garage at least 6x6m (20x20 feet) or larger to accommodate bicycles and children’s toys.
How would you position the garage? I’m not fully satisfied. A large garage would be nice, maybe even 8m length (26 feet) for a caravan? Though probably too big to fit.

Lawn/garden for playing football and children to run around.

House Design
Planner from a construction company

What do you like most? Why?
Practical layout with smooth transition to the outdoors from the living room, open roof, exposed beams would be nice but complicated and expensive due to double-layer construction.

What do you dislike? Why?
South elevation top, balcony design, window depths, and arrangement – we are unsure. It lacks some flair in the layout.

We welcome ideas or suggestions – do you see things or approaches that we don’t, new perspectives or things we might have completely
forgotten or overestimated?

Cost estimate according to architect/planner:
Open, quote pending

Personal budget limit for the house including fittings:
Still in the budgeting phase and not fully clear yet

Preferred heating technology:
Open to anything – underfloor heating is mandatory

If you had to give up something, what features or extras
-can you go without:
Studio

-can’t you do without:
Home office

Why is the design the way it is now?
E.g., number and function of rooms, competitor offer as a basis, necessity of the layout due to the plot

What is the most important/fundamental question about the floor plan in 130 characters?
What implementation ideas do you have that we haven’t considered to optimize the plot use? Ideas for the house to inspire or ground us welcome. First build.

Plot plan:

Site plan of a building plot with boundary lines, buildings, and colorful markings


Neighborhood and roof shapes, etc.

Site plan of a street intersection: blue property boundaries, pink building areas, yellow roads


Basement floor plan

Basement floor plan with rooms for hobby, technical/laundry, and hallway; exterior walls marked red


Ground floor plan

Ground floor plan of a single-family house with living room, kitchen, terrace, garden, driveway, garage


Upper floor plan

Upper floor plan showing bedroom, bathroom, studio, rooms 1–2, hallway, dressing room, balcony


Section

Cross-section of multi-storey house with basement, stairwell, roof ridge, windows, foundation


Possible 3D renderings

Modern two-story white house front with wood cladding, garage on left, driveway, and garden


Modern white two-story house with large glass front, balcony, and garden terrace


Thanks for all opinions and ideas.

Just a quick question that might be a bit silly. The green circle marked in front of your driveway—is that a tree? Is it already planted, or do you plan to put it there? That would probably make it quite difficult to drive in and out of the garage.

I would install a kitchen window facing the garage despite the limited view. It still lets in natural light. Then you could cover the garage wall with some kind of greenery.

I personally like having a balcony on the upper floor. Although we have a large garden, the balcony was used as an alternative space quite often. When my boys played in the garden with many friends, I could retreat there, and later it became a reading spot for the older kids when the activity on the trampoline in the garden got too noisy. It also provides some shade at times. Those are just our experiences.

Regarding the angled garages: If we align the garages straight, then we need 5.00 m (16 feet) of parking space in front of the garage plus 6.00 m (20 feet) garage length, pushing the building footprint further south.

Yes, I wouldn’t want that either. But just based on the sketch, I don’t think it would be practical to regularly park and maneuver the vehicles there. It would especially annoy me a lot. That’s why I suggested a carport, hoping it might not have to meet those distance requirements (as is often the case).

About the kitchen window: Yes, the view isn’t great. Of course, the neighbor’s garage is also there. Moving the kitchen to the other side facing northwest wouldn’t work either, because of the transformer station there.


Isn’t the transformer station only on the north side? The west side would be much better for the kitchen window than looking at the garage twice. Or do you prefer the nicer view to be for the study instead?

@Ibdk14: Yes, the green circle marks a tree, and there is a planting requirement. We need to figure out how to implement this. We are not really excited about having to rotate the garages. Alternatively, we would have to move 1.50 m (5 feet) further south and reduce the size of the garden. I had the idea of an angled garage, but then there would be no view from the kitchen window.

@kaho674: Placing the kitchen on the west side was an idea, but the downside is that although you get a nice view, no sunlight comes in there, and we would end up with a rotated layout with the living room on the south side. The plan was to have the dining area in the southeast (morning sun) and the living area in the southwest (evening sun).

I want floor-to-ceiling windows in the kitchen. The 3D simulation showing my neighbor’s garage indicates that depending on the season, from around 8:30 a.m., sunlight can directly enter the kitchen, so there will be some natural light. We could also give up some of our west-facing area and set the house back by 3.50 m (11.5 feet) or even 4.00 m (13 feet).

Another idea was to create the driveway between the transformer station and the house; the distance from the house is about 3.00 m (10 feet), which would allow direct access to the angled garage. According to the development plan, garages can be built right on the property boundary, meaning no setback from neighbors is required and just 0.50 m (20 inches) distance to public spaces.

Ok

Ok, I wouldn’t have expected that.

Garages or carports?

Garage. According to the building regulations in Baden-Württemberg, a 9.00 m (29.5 ft) garage may be built on the boundary line up to a wall height of 3.00 m (9.8 ft).

Yes, but to get back to the main point, usually carports do not need to maintain a 5m (16 feet) distance from the street. This would mean that you can drive straight in with the car and the structure can remain as far north as possible. However, this varies in every municipality, and the question was how it is handled in your area and whether this wouldn’t be the better option compared to what I consider the impossible turn?
