Good morning everyone,

we are building a single-family house with approximately 200 sqm (2,150 sq ft) of living space on a beautiful sloped plot not far from the city center. We shared some initial drafts a few months ago. Since a lot has changed since then, we are posting the current planning status again and look forward to the discussions:

Development plan/restrictions: development plan
Plot size: 500 sqm (5,380 sq ft)
Slope: yes, about 6 m (20 ft) drop over 28 m (92 ft) plot length (southeast facing slope)
Floor area ratio: 0.2
Plot ratio: 0.3 (variations are expected to be approved if the floor area ratio is respected)
Building envelope, building line and boundaries: standard setback distances
Edge development: garage will be built on the boundary line, which is permitted
Number of parking spaces: 1 + garage driveway
Number of storeys: I + IS (meaning 1 full floor + basement level → basement on the slope)
Roof style: no specification
Architectural style: no specification
Orientation: ridge must run east-west
Maximum heights/limits: eaves max. 3.60 m (11.8 ft) above street level
Other requirements

Homeowners’ requirements
Style, roof type, building type: gable roof with 48° pitch
Basement, floors: basement level – to be used as primary living space on the south slope with access to the terrace
Number of people, ages: parents just over 30, children 0 and 2 years old
Space requirements for ground floor and upper floor: ground floor: main living area and kitchen; upper floor: 3 bedrooms + bathroom; basement: summer living room/playroom with garden access, guest room
Office use: possibly a studio office under the roof (not a decisive factor)
Guests per year: long-term visits anticipated
Open or closed architecture: open
Traditional or modern construction: classic form with large, high windows
Open kitchen, kitchen island: open kitchen with cold island and seating
Number of dining seats: 6
Fireplace: probably yes, but as an external chimney
Music/stereo wall: no
Balcony, roof terrace: no
Garage, carport: prefabricated garage with masonry undercroft
Utility garden, greenhouse: no
Further wishes/special features/daily routine, including reasons why certain things should be included or excluded:

terrace access at ground level from the basement
photovoltaic system

House design
Who designed it:
- Planner from a construction company (civil engineer) / self-planned by homeowners

What do you particularly like? Why? Large basement room with terrace access. Comfortable overnight accommodation for guests.
What don’t you like? Why? The stair shape is very functional; it optimizes space usage on the upper floor and generally towards the south side of the house. A straight staircase would be preferred visually, though.
The current full storey definition according to the Bavarian Building Code of 1969 forbids, for example, raising the knee wall or adding a second dormer on the upper floor.
Estimated cost according to architect/planner: €360,000
Personal price limit for the house including fixtures: 400,000
Preferred heating technology: air-to-water heat pump

If you have to give up something, what details/finishes can you live without?
- Can give up: photovoltaic system
- Cannot give up: basement with living-quality standards

Why does the design look the way it does? For example:
Based on the plot conditions and the development plan, we have completely redesigned the first draft step by step, incorporating inspiration from this forum and new build areas (offline) / Pinterest and similar sources (online).

Currently, we are still considering the following questions:
- Floor-to-ceiling windows on the south side: single- or double-leaf? Originally double-leaf with 150 cm (60 inches) width planned. We prefer the look without the division, but then probably max. 120 cm (47 inches) wide would be possible.
- Fixed glazing as a large light strip on the southwest corner of the basement or rather two windows aligned with those above on the west facade?
- Omit the window in the small basement room on the northwest side to improve facade appearance?
- Add 2 extra roof windows next to the dormer on the upper floor to bring more light to the children’s rooms?
- Flooring on ground and basement floors: upper floor will have parquet; still undecided between parquet, continuous granite flooring, or exposed screed/smooth floor for the other two levels

We look forward to your comments!

Usually, when building a house, you don’t start from being homeless but already have experience living in an apartment or house (Is the dining table too close to the sideboard? Do you have to run the same marathon to fry an egg in the kitchen as you do for a wedding menu?). This simple option—to draw your current home and mark in red what you find inconvenient—is available to every future homeowner. Therefore, I don’t understand how anyone can struggle so much to find a proper starting point. Surely, finding graph paper and a tape measure shouldn’t be a problem. This is far more helpful than getting overwhelmed by show homes and trying to squeeze a standard model house onto your plot just because “the perfect house must be found,” or, like in your case, having the planner take a floor plan they have been pushing since 1950 for the Müllers just as readily as for the Meiers, only to alter it slightly by adding a secondary living room in the basement.

Hello everyone,

here are new, furnished floor plans for the (residential) basement and ground floor – however, we have changed the room layout and stair design again because, among other things, Maria was right that the room would otherwise be difficult to furnish. We are still undecided about the attic floor, so there is no floor plan for it yet --> but it could later accommodate a large master area and an additional bathroom.

@Maria: By other points, I mainly meant considerations about the size of the wardrobe area, master bathroom/children’s bathroom versus family bathroom, etc., which are secondary for us and should fit into an otherwise coherent floor plan.

In fact, over the last six months we have spent a large part of our free time focusing on such considerations and have had many, unfortunately not very productive, meetings with our home builder. Of course, you wouldn’t be able to tell this if we haven’t posted here for a while – so we understand your reactions.

Now we hope to receive more helpful suggestions from you here.

House floor plan: master bedroom, two children’s rooms, bathroom, hallway/landing, entrance area/wardrobe


House floor plan: open living-cooking-dining area, bedroom, utility room, stairs, and balcony.

Tell me: You always plan very generously, bigger than necessary ... is the budget available for this size? I still think: reduce by one meter (3 feet) on each side and instead hire an architect [emoji2]

Yes, in the end, the volume is too much. If I remember correctly, a 45° roof pitch is required (?), then the reduction must be applied to the floor area.

Hello, regarding the budget: the financing is secured, and the current shell construction offers give us hope that we will come close to the planned amount.

A gable roof is required by the city due to the “ensemble-protected” streetscape—> However, we can definitely make good use of the space in the attic because the grandparents often stay for several months and could have their own area there.
We have already scheduled an appointment with an architect for next week. We really appreciate your tips (which is why the living room is now in the basement) and if you have any further recommendations on the current design, we would be happy to consider them during our meeting.

Wow, you’re getting quotes for the shell construction and even have financing secured, but in the end still don’t have a floor plan? I find that a bit risky.
