Hello everyone, we are looking for a floor plan for a semi-detached house!
Most semi-detached houses are long and narrow, but our building area does not allow that.
We want to live in one half of the semi-detached house
And rent out the other half. We prefer not to be alone.
Development plan / restrictions
There is only one supplementary ordinance. Construction according to Paragraph 34.
Size of the plot: 815 sqm (8770 sq ft)
Open construction method according to Paragraph 34.
Slope: yes, over 16 m (52 ft) there is a 1.5 - 2 m (5 - 6.5 ft) gradient.
Floor area ratio: 0.4
Floor space index: not specified anywhere.
Building area, building line, and boundary
8.5 m x 16 m (28 ft x 52 ft) according to surveyor.
Edge development: no
Number of parking spaces: flexible
Number of floors: 1.5 - 2 (neighbors)
Roof shape: gable roof > 35 degrees
Architectural style: classic mixed with modern
Orientation: see drawing
Maximum heights / limits: unknown
Other requirements
Homeowners’ requirements:
Style, roof shape, building type
Classic-modern, gable roof, semi-detached house
Basement: yes, floors 1.5 - 2
Number of people: 3 adults, 2 children, 1 toddler
Room requirements on ground floor: kitchen, living room, dining room, shower bathroom
Upper floor: master bedroom, two children’s rooms, bathroom.
Office: nice to have, but not mandatory – home office!
Guests sleeping overnight per year: none
Open or closed architecture: open
Conservative or modern construction: flexible
Open kitchen, cooking island: would be great
Number of dining seats: 8
Fireplace: no
Music/stereo wall: no
Balcony, roof terrace: no
Garage, carport: yes, 2 spaces
Utility garden, greenhouse
Other: 1 garden north, 2 gardens south
Requests / special features / daily routine, also reasons why this or that should or should not be included: we are open to everything, we want to build something that makes sense! It does not need to be large! We currently live in 102 sqm (1100 sq ft) plus basement and that is sufficient.
House design
Who is responsible for the planning:
We do not have one yet! The plan below would be acceptable for us, but it needs to be made quite square. Has anyone worked on a similar project?
- Architect: We want an architect to help us but do not want to hire one unprepared.
- DIY: That’s why we want to gather as much input as possible.
What do you particularly like? To make full use of the building area, if possible. Why? So that there is not a 100-130 sqm (1075-1400 sq ft) house on an 815 sqm (8770 sq ft) plot, and we would like to have neighbors!
What do you not like? The 8.5 m (28 ft) width of the building area. Why? 10 m (33 ft) would be optimal for a nice semi-detached house.
Price estimate according to architect/planner:
700,000 euros without land!
Personal price limit for the house including equipment: 400,000 euros per semi-detached half
Preferred heating system: solar thermal combined with gas
If you had to compromise on details/additions:
- What could you live without: office
- What can you not live without: large kitchen, all activity centers around the kitchen and dining room, we hardly ever use the living room!
Why is the current design the way it is?
We actually do not have one.
Standard design from planner? Yes
Which requests were implemented by the architect?
A mixture of many examples from different prefabricated house catalogs.
What do you think makes it particularly good or bad?
No compromise on the kitchen, as it is our central living space.
Bad: possibly planning a semi-detached house, maybe better a house with a granny flat?
What is the most important/basic question about the floor plan summarized in 130 characters?
How can we combine family life with spatial design in one half of a semi-detached house?

And now we are supposed to look back, figure out how your lot looked before, where the house might have been roughly positioned on it, and where north would be in each case?You can do that if you want, but all the pictures are oriented roughly toward north except for Fingerhaus, where you can see the terrace, which is supposed to be on the north side.
Part of my intention is that other builders might read along and possibly take away something useful for themselves or even offer another tip.
Good luck
Hello everyone, we have decided on the architect, and she is helping us with the building permit / planning permission application. After that, we will start looking for a general contractor! Alternatively, after receiving the building permit / planning permission, we might hire a construction manager and complete much of the work ourselves to build the house.
Here is the architect’s first draft.
We have already commissioned the following changes:
- New size: 8.5m × 12m (28ft × 39ft)
- Separate basement room directly next to the stairs in the basement, about 20–25sqm (215–270 sqft)
- We want the kitchen arranged differently, probably on the south side...
We appreciate any tips or suggestions.
Regards

Better to reopen it? I thought it would be better to continue here......
No, not new, but when posting a new floor plan, it’s helpful to include the key details again, possibly also adding the site plan as additional information, etc.
On the ground floor, I would place the kitchen facing the terrace, the dining area in the center, and the living room as planned towards the street side. It’s also useful to occasionally sketch a realistic kitchen layout.

Hello everyone, understood. Sorry, I didn’t mean to catch you off guard. We are currently working on the floor plan and are slowly getting overwhelmed.
I’ll write some more about it!
We want to build in 2019 with an architect who will support us only up to the building permit / planning permission stage. After that, an experienced site manager will take over together with the structural engineer. Each trade will be put out to tender individually.
There are 4 of us: 33, 32, 4, and 2 years old. Grandpa is going to move in as well, but not for a few years.
The plot is 815 sqm (8775 sq ft) and accessible from the south. It’s about 20 m (65 ft) to the building area, a long narrow plot with a slope.
The gradient in the building area is approximately 1.5 m (5 ft) over 16 m (52 ft).
We are allowed to build 8.5 × 16 m (28 ft × 52 ft).
We want a gable roof with a 35-degree pitch.
The house should be about 12 m × 8.5 m (39 ft × 28 ft), approximately 1000 cubic meters (35,300 cubic feet) of remodeling space.
It will have a two-layer masonry wall with clinker brick, 42.5 cm (17 inches) thick.
We are satisfied with the basement layout and would like grandpa to have a large south-facing front with a terrace and a separate entrance.
The entrance and driveway should be on the east side.
The terrace should face north with a slight tilt toward the west. The neighbors are 6 m (20 ft) away, and they are building a two-story house without a basement, so their living space is somewhat lower.
We want to place the kitchen on the east side,
the living room on the south side with a balcony (not yet drawn),
the dining area on the west side,
and an office on the south side, which could also be a dressing room and storage space…
Is the hallway wide enough? It’s 1.5 m (5 ft) wide.
Do you have any tips? What would you do differently or how would you organize the rooms?
Our idea was to have a large window with a balcony door in the living room to let in light from the southwest, as well as windows on the west side.
We are happy with the upstairs plan except for the children’s rooms, which we’d like to be around 17-18 sqm (183-194 sq ft).
But we have to think in three dimensions, which doesn’t work downstairs! Should we extend to 13 m (43 ft)? Would that fit everything? But that’s already quite large.
We would appreciate any advice.
The window planning will be done once the floor plan is finalized.
The basement bathroom will be twice as large, which bothers us.
The driveway is a concern for us.
The street is at 304.5 m (999 ft) above sea level, the house is planned to be at 305 m (1,001 ft), and the ground floor entrance would be at 308 m (1,010 ft). The entrance is about 25 m (82 ft) from the street, which is a 3.5 m (11 ft) slope over 25 m (82 ft). We were thinking of a carport, but our architect suggested putting the garage at 305 m (1,001 ft) and walking around the garage to the entrance, which sounds horrible to us.
I hope I didn’t forget anything and look forward to your tips. Thank you!
