Hello dear community,

we are considering adding an additional floor to a Kampa bungalow built with timber frame construction. An alternative would be something completely different or a demolition, or to build "around" it once.

Currently, we live in the aforementioned bungalow. Over the past years, the previous owner and we have done a lot. For example: new bathroom, new guest WC, all floors renewed, all ceilings renewed, all interior walls insulated with a type of super styrofoam, new kitchen, basement expanded, new windows, new front door, roof newly insulated, outdoor facilities completely redesigned in front and back, building technology optimized, new switches, sockets and electric blinds installed, network cables laid throughout the house,....
That should roughly cover the most important things.

Unfortunately, it has since become too small for us due to the new addition to the family, and we only like it about 75%. We would really like it to be "cool"! We are considering whether to add a floor and renew a lot again and "properly." Our idea in this process is also to bring the house up to date in terms of energy technology (heat pump, possibly solar?! - currently oil). We would like to install underfloor heating everywhere. The first floor should be very open with large window areas. The bathroom should also be on the first floor (structural reasons). On the ground floor, we would like to rearrange the interior walls and also install a fireplace. If possible, this can also be connected to the water heating. And so on....
The two floors should ideally be connected by a new staircase, which should be realized as an "extension." There is enough space on the property (approx. 1,000 sqm).
The existing basement should continue to be used. (Is that even possible, what needs to be considered)

Now my question(s):
Is there a way to enclose the house with a solid construction and then gradually dismantle the old one, so we can live in it in parallel, or is that too much effort and cost?
- Alternatively, can you add a floor without structural problems? - Is it then possible to significantly improve thermal insulation (heat pump, door blower test)?
- Do you have other ideas that I currently do not see?

If anyone has faced similar problems and has ideas, I would be very grateful.
Have a pleasant Sunday and many thanks!
Hans v. D.

Interior walls all insulated with a type of super styrofoam PU? Spaceloft? Why is that? So, demolition without moving out seems difficult to me.

They were about 0.7 cm thick styrofoam boards that we glued to the inside of the walls before wallpapering. Why? – well, we thought it would help with insulation?! Hope it does. Regarding the demolition, the question remains whether it is necessary at all?!

My reaction only, since there are also rather critical opinions about Styrofoam insulation and especially Styrofoam interior insulation.

Year of construction would be interesting. If you don't like the floor plan and don't feel comfortable and need to enlarge, and the building fabric is questionable, demolition might not be the worst choice. Go to an expert, get a cost estimate calculated for the options (surely costs a few euros, but in the end you have a basis for decision) – I believe the whole thing might actually be rather complex.

Hello,

You should definitely first get a structural engineer to your house who can determine whether you can even build on top of the existing basement and ground floor without having to make major changes.

All other questions can only be clarified then anyway.

Regards,

Dirk

I would also first consult an architect and a structural engineer. Alone to know what you can still get out of your bungalow, and what a renovation and a new build would cost. Because if a new build becomes cheaper than a renovation, then the question is already answered. And you can also build a new house on an old basement. Everything is possible. But giving remote diagnoses is difficult.
