Good evening everyone,

We recently purchased a fully serviced plot of land in our small town (in northern NRW) and have been working on planning the right house for us for some time. The current floor plan comes from a general contractor, and the challenge is that our house should be as compact as possible (to keep costs from skyrocketing) but still provide enough space for a family of five plus my parents.

Development plan/restrictions
Plot size: 472m2 (5,078 sq ft)
Slope: no
Site coverage ratio: 0.4
Number of parking spaces: 4
Number of floors: 2 (mandatory)
Roof style: open
Maximum heights/limits: max. 10m total height / max. 7m roof height
Other requirements: none (max. 2 residential units)

Client requirements
Style, roof type, building type: urban villa with setback floor
Basement, floors: no / 3
Number of people, ages: 5 (42, 37, 16, 13, 6) plus 2 retirees
Room requirements on ground floor (GF), upper floor (UF):
Office: family use rather than home office
Annual guest stays: 5 times
Open or closed layout: open
Conservative or modern design: modern
Open kitchen, kitchen island: open kitchen, no island
Number of dining seats: 5
Fireplace: no
Music/stereo wall: no
Balcony, roof terrace: yes / yes
Garage, carport: carport
Other wishes/special features/daily routine, including reasons why some options are preferred or excluded:

Our wish was to build a relatively small, compact two-family house on a small plot (472m2) so that we would still have a sufficiently large garden. Initially, we considered planning a separate apartment for my parents, with our living/dining area on the ground floor. However, we quickly realized that a two-full-floor house without an attic conversion would become too wide (about 14.5m (48 feet)), leaving us with hardly any garden. We do not want to convert the attic because we dislike sloped ceilings. We are aware that we have to compromise and build three stories so that the building footprint is not too large. Since my parents are already over 70, their apartment must be on the ground floor, meaning our apartment will be on the first and second floors. Because the roof height may not exceed 7m (23 feet) and we want to avoid sloped ceilings, only a setback floor was feasible for the attic. We actually like the setback floor because it also allows for a roof terrace.

The downside is that we wouldn’t have direct access to the garden from our apartment. This drawback is somewhat bearable because we have three outdoor options: the garden via the stairwell, balcony, and roof terrace. Of course, direct garden access would be better, but we want to grant that to my parents 🙂. If they are no longer with us someday, we would move down and rent out the apartment upstairs or give it to one of the children. Basically, we don’t mind living with others in one house. Currently, we live in a three-family house: we are on the ground floor, my parents upstairs, and acquaintances in the attic. The planned house could theoretically also be used as a three-family house eventually.

House design
Who designed it:
- Planner from a construction company: general contractor
What do you particularly like and why? The house is relatively compact, with sufficient garden space and a roof terrace
What don’t you like? Possibly too small, too compact?
Price estimate according to architect/planner: €540,000 (KfW 40+ house)
Personal price limit for the house, including equipment: €570,000
Preferred heating system: geothermal (only this heating system is offered in the development)

If you had to forgo something, which details/extra features:
- can you do without: balcony
- cannot do without: two residential units

Why is the design as it is now?
Standard design from planner? The design emerged because we want to build a compact house with two residential units.
Which wishes from you were implemented by the architect? Basically all
What do you consider particularly good or bad? The setback floor, free garden area are good; perhaps the room layout overall is not ideal

What is the most important/fundamental question about the floor plan in 130 characters?

Is the house big enough for us and my parents? Did we overlook anything? Is the living/dining area too small? No guest toilet (a problem?), enough storage space? Any feedback on the house is welcome. We are very curious to hear what the experts in this forum think about our project.

Thank you very much and best regards
Claudia

I don’t even know where to start, this just won’t work as is. So, I’ll just pick two appetizers: the maximum eaves height of 7 meters (23 feet) is definitely exceeded here, and you’ll also need to consider space for at least three parking spots.

For a house of this size, I consider the proposed budget to be too low.

I wouldn’t be so sure about that. In our building area, only 6.5 m (21 feet) eave height is allowed, but in the written regulations it states that for recessed upper floors the eave height is measured at the intersection of the exterior wall with the ceiling of the top full story. Some builders have taken advantage of this rule just like shown here.

What requirements do your parents have for the granny flat? A detailed room layout,
such as a bedroom with a 4 m (13 ft) built-in wardrobe,
a living room with an XXL sofa and bookshelf approximately 5 m (16 ft) high.
Also, consider which handicaps they need to accommodate while living in the apartment.

The same applies to your place. Create a precise room layout with the necessary furniture and dimensions.

Draw all furniture to scale, including clearance space.
For example, for a dining table, assume at least 80 cm (31.5 inches) of free movement space measured from the table edge. In other words, for a table 1 m (3.3 ft) wide, you need a minimum of 2.60 m (8.5 ft) of total width.
This way, you will see if your living area is too small.
I would plan the open living space on the top floor, so you have direct access to the outdoor dining area.

I would arrange a drug test at the building authority and the legal department – you can take my word for it, as they say in the precinct. I at least hope this is an isolated case and that the zoning plan for the original poster does not so casually approve a mere change of facade color as an “eaves height.”
