Achenbach prefab house 1980 uninsulated - insulation costs

Hello,

we have been offered a prefab house from Achenbach (no information about this company can be found, the usual thickness of the walls from this period can be deduced from the floor plan) from 1980, which has received a new heating system but is otherwise completely uninsulated :mad: - original condition 1980. Since the house is very interesting in terms of floor plan, plot, and location :) I am now asking what a high-quality insulation roughly costs.

The house is an L-shaped bungalow, fully basemented, about 124 sqm of living space. The price is so affordable that we can afford to invest up to about 50,000 euros in an energy renovation. Nevertheless, the whole thing would still be cheaper than a comparable new build. The question is whether that is sufficient.

Thanks in advance for all answers

Hello,
with 50,000 EUR you can already do something. :)

The best thing is to get the energy consultant you trust. He can tell you which measure makes sense and what it approximately costs.

Hello,

...The best thing is to get the energy consultant you trust.

Trust is all well and good but does not replace expertise. Energy consultant is a legally unprotected professional title! Ideally, they should be an MEP planner and have a building engineering education (degree). The energetic refurbishment of existing buildings is significantly more demanding and complex than planning a new building. Without appropriate professional support, the initially inexpensive property can quickly become a money pit.

Best regards

I see it the same way.

The renovation of existing buildings should definitely be left to architects or civil engineers. However, they must also know what they can and cannot do. If the architect/civil engineer leaves their area of expertise, a specialist engineer must be involved (TGA planner, structural engineer, etc.).

The energy consultant should of course have knowledge in both areas of expertise (building and systems engineering).

Correct,


we absolutely had no intention of making things worse by ourselves with Styrofoam or similar, but rather to entrust the whole thing to a specialist company with the appropriate experts who specialize in renovating prefabricated houses. We would also get quotes from various companies.


In addition to the energy renovation, the bathroom and partly the floor coverings need to be done on the house; this is not included in the planned 50,000 but is in our financing plan. We have no idea what an energy renovation might cost. We have just completed the first short inspection; supposedly there is a building biology report stating that formaldehyde and the usual suspects are below the limit values (probably 30 years of continuous ventilation through the thin walls :)), so we can focus on the energy renovation and the rest. But there are also other houses available to us, so we do not necessarily have to concentrate on this one, although we like it.


But before we involve surveyors etc., I wanted to know whether one can roughly manage with this amount (if necessary a bit more, preferably less).

But at least get someone who supervises the construction work. Or better, someone who plans and supervises.

But before we involve appraisers, etc., I wanted to know whether you can roughly manage with this amount (if necessary a bit more, preferably less).

It depends on what you want or need to do.
50,000 EUR initially sounds quite good. But to decide if it is enough, you need to know the house and the extent of the measures.
