Because many of you are asking about the new building, I’d like to show you the thought process behind this idea and ask for your feedback. I hope the line of thought is understandable.

More information about the house also helps with understanding.



- It is a semi-detached house with the mentioned extension
- on the ground floor my mother lives (right of residence)
- on the upper floor we live (myself, my wife, three girls (5 months, 4 years, 6 years))
- on the attic floor lives the tenant. The room layout is bad and historically developed. Therefore, at some point, the former parents’ room in the attic became a separate room outside the rental apartment. The access from that room to the rental apartment was closed and a new door was installed. So, when you arrive in the attic, there are three doors. To the left the toilet, straight ahead the entrance to the rental apartment, and to the right access to the office. Above that is the old pull-out door to the attic storage. The layout is obviously absolutely terrible. I didn’t build it.



Here is the basement:



Here ground floor and upper floor:



So, how did we come up with the idea of a new build?

We have now been a family of five for five months. When we were four, we of course knew that at some point we’d need more space, but when the youngest came along, we addressed it more intensively. Five people in 84 sqm (that’s the size of ground and upper floor) is of course not enough. We’re not in a rush, as the children still share a room anyway. But in two years we should be done with “more space.”

At first, we had the idea to simply build up on the upper floor, stone upon stone. My mother on the ground floor does not need more space. Then I thought about taking her living room as living space for us. It was important that we wanted a separate entrance. If you had connected the living rooms of the ground and upper floors, you would have a separate entrance and a bit more space. But that’s still not really enough for several rooms, and I couldn’t come up with a decent floor plan either. An access to the office and attic would be great with an extension but not really feasible. At least I couldn’t think of anything.

Then I “googled around” and eventually came across tiny houses, flying spaces, etc. Then I thought one could build such a container/space on stilts and attach it to the north side (garden) of the upper floor and add three children’s rooms. That was an interesting idea at first.

Then we were told that such an addition would be so expensive that with “a bit more” you might as well build completely new.

That gave rise to the idea of putting up a separate house. This would have the advantage that we could move out of the upper floor and into the new house, thus making the apartment rentable as well. Eventually, when my mother is “no longer here,” there would be three rental units, and in the distant future, three apartments for three children. Whether they want to use them or not. And theoretically, it could later be possible to demolish the old building and build something new there again.

And then it was there, the idea of a house in the garden.

I hope that makes it clearer?

Then came talks with the planning office and the problems with setback distances and parking spaces. We could now, if we build an extension to the garage in the west and build up to 3 m from the neighbor in the east, build to 9 m width. About 11.5 m is the distance to the northern boundary. If you leave a small passage to the garage, you get 8.5 x 8.5 m. We would need 6 parking spaces (because of the new dwelling unit). It is currently being clarified by the building authority whether we need a guest parking space. Then it would be 7 and even more problematic.

So, I hope I was able to explain the problem and the history in a somewhat understandable way? :)

I’m now looking forward to your collective intelligence. :)

Simply to get suggestions regarding size and necessity. I have never built before. I didn't realize that a utility room is necessary. By now it makes sense. But you have to come to that realization first. The same goes for the size of the rooms, bathrooms, etc.

The connections and heating have to go somewhere. And laundry, freezer, and storage space are even more necessary with 3 children than in a smaller household. Even without the photos, everything is well explained in the initial post, including the semi-detached house, etc. The floor plan of the attic and the cross-section broaden the horizon. Nevertheless, nothing changes for me: renovation of the existing building, conversion of the attic into three children's rooms plus an office/guest room. Quite feasible with an architect. Better a scare with an end (temporary move-out) than a scare without an end (total overbuilding of the property).

I would terminate the tenant due to personal use. Then you have enough space.

I can absolutely understand the thought process of wanting to have a new, beautiful house, but I believe that is the wrong way. 1. You would completely destroy your beautiful property and 2. I don’t think you will be much happier with 8.5m x 8.5m. With 5 people + an office, you need at least three floors, otherwise it will be very tight and you will almost have no garden left. Aside from the fact that everything first has to be approved. That is also still uncertain. Have you considered selling your house and looking for another property nearby? From your pictures, it looks quite rural, at least not downtown. Is there nothing like that? Then you build there with a granny flat for your mother-in-law. Or 2nd option: really completely renovate the house, including changing the floor plan. It also occurred to me that even if you do build a new house now, sooner or later you will still have to renovate the old house if you want to keep renting it out. In that scenario, you might actually end up paying twice. New house + renovation of the old house. That can really get tight. At the very least, you will definitely have to pay for demolition, but then with the new house you have the problem that one wall is completely windowless and that is even the wall facing the street.
