Hello, I have created the floor plan for a duplex bungalow with two rental units. There is a utility room planned with one heating system for both apartments.

Development Plan/Restrictions
Plot size: 700 - 900 sqm (7,535 - 9,688 sq ft)
Slope: No
Floor area ratio (FAR): 0.4
Site occupancy index: 1
Number of parking spaces: 1 on the left, 1 on the right
Number of floors: 1
Roof shape:
Orientation: not yet fixed
Maximum height/limits:
Additional requirements: 4.50 m (15 ft) maximum eaves height

House Design
Who designed it:
- Do-it-Yourself

What do you like especially? Why?
No wasted space, hallway as small as possible without feeling cramped.

What don’t you like? Why? Bedrooms and study too small?

My cost estimate:
€350,000 including 2 carports and the plot (€40,000)
Preferred heating system: air-to-water heat pump

If you had to give up, which details or features could you do without?
- Could give up: carport, instead of a hip roof a flat roof (6 percent slope)

Why is the design the way it is? For example:
In our new residential area (we moved into our single-family house last year), someone built something similar. Their apartments each have 99 sqm (1,065 sq ft). I optimized a bit and reduced the hallway size. Otherwise, much is adopted.

I think it’s good that there is only one utility room. Also, the distances are short (for pipes and walking paths).

Currently, two types of plots are being sold here. [...] And then larger plots ranging from 700 to 950 square meters (7,535 to 10,225 square feet) for families with children. [...]
According to the municipality, the plot data will be as follows:
Plot ratio (Grundflächenzahl): 0.3
- Floor area ratio (Geschossflächenzahl): 0.3
- Number of full stories: 1
- Detached single-family houses or single and semi-detached houses allowed

In that case, if I were you, I would design a one-and-a-half-story building, with one half sized around 700 m² (7,535 sq ft) and the other around 950 m² (10,225 sq ft), both “modular” plus additional rooms.

Those are different values now… and it’s quite bold to plan almost 250 sqm (2,690 sq ft) of ground floor area WITHOUT the terrace (which will be added), including carport and driveway, when only 210 - 270 sqm (2,260 - 2,906 sq ft) are allowed. Ecologically it’s a disaster; economically, I’m not sure.

But the very first rule is: start with the plot, then you can plan!

If you have to cut back, on which details / additions
You could do without: carports, replace the hip roof with a flat roof (6 percent slope)

Why did the design turn out this way? For example
In our new development (we moved into our single-family home last year), someone built something similar. Their apartments are each 99 sqm (1,065 sq ft). I optimized a bit by reducing the hallway. Otherwise, much was adopted.

I like that there is only one utility room for heating. Also, the runs (pipes and foot traffic) are short.

The land price suggests a low-demand location.
For barrier-free rental, I would plan a multi-family building with an elevator featuring well-designed two-room apartments where you can easily turn with a walker in all directions, close to a (spa) park and near the city center but with a large plot for parking. Your idea wouldn’t have occurred to me for third-party rentals, sorry.

Are you following along as well?

For a single-story building, an elevator is not necessary.

I will reconsider the issue of choosing between a bungalow or a one-and-a-half-story house and continue following the modular system from 11ant.

From an economic point of view, certain disadvantages don’t bother me up to a certain extent if I can use the apartment myself in old age. I only see that as an option with a bungalow.

Based on your experience, can you say what kind of deficit might occur if you compare a bungalow to a one-and-a-half-story house of the same size for rental purposes? How can this be assessed?

Building for more than two households would certainly be possible somewhere in our community on available plots. But I don’t feel confident about that. You would already need around 600,000 to 1,000,000 (depending on units and land) to invest. Of course, this roughly balances out with rental income. But somehow, I can’t wrap my head around it.

0.4 was indeed still an old value (from our building zone).

Yes, it will be tight. But driveways, carports, etc., under certain conditions, only count as half, as I have read.

Besides, I wonder who actually checks that. The house with the flat roof from my pictures has 99 sqm (1065 sq ft) per dwelling unit on a 750 sqm (8070 sq ft) lot. He will also add 2 carports with a driveway (although usually only one driveway is allowed). His application was fully approved.
