Hello Forum!
We have been looking more closely into the topic of building our own home for a few months now.
We have the opportunity to purchase a plot of land at a reasonable price. If we go ahead with this, our budget for the house would be around 150,000 to 160,000 Euros.
With this budget, we would like a house with a basement, about 130 square meters (1,400 square feet) of living space, that ideally meets the Energy Efficiency House 70 standard.
Self-build work would be possible, although I’m not sure to what extent. I would say I’m fairly handy and have also helped with building my parents’ house.
We’re just not sure if it’s possible to realize our ideas within this price range.
We have seen a house that might fit... Am I allowed to mention the name here? (Company Ha..mann Haus)
That would cost around 140,000 Euros with a basement, in a painter-ready condition.
I hope someone here has experience with this and can offer us some guidance...

And what leads you to this statement?

Hello!
Thank you first of all for the responses.
I’m a bit wiser now. I assume that I can probably forget the whole thing. Doing some of the work ourselves was considered, but since we both work in shifts and rarely have time together, the renovation would likely take a very long time. Also, since we are currently renting, the double financial burden would be too much for us to manage...
So I guess it will have to remain a dream after all!
Still, thanks for your efforts!
Best regards

Try to build up some equity. The KfW will most likely continue their programs until 2020, as the EU decision would only be implemented by then.
For energy-efficient houses, you also need time and nerves. If it drags on too long, the motivation simply fades.
@Bauexperte
The building envelope shown here, excluding the technical building installations (TGA).
Moreover, there are only a few who can properly plan and execute with aerated concrete or clay blocks. Many aspects require special solutions, which come at a cost. I would advise to stay away from cheap options. Thermal bridges form far too easily, or the load-bearing capacity limits get reached. Also, there is no masonry material more prone to cracking.

Yes, that would be an option, although we currently had the chance to buy a plot of land at a low price. That probably won’t happen so quickly in the future, at least not for 85 €/sqm (8 USD/sq ft).
So it will probably become even less feasible!
What bothers me is that the same amount we could save each month is being thrown away every month on rent. For example, if I could save €6000 (about $6,500) annually, I would frustratingly lose the same amount of money without any return… 🙁
Well, there’s no helping it...

The calculated annual primary energy demand QP is 55.15 kWh/(m2 a) andthus meets the minimum requirement of no more than 70% of the calculated maximum value for the reference building according to Table 1 of Annex 1 of the Energy Saving Ordinance 2009, which is 89.24 kWh/(m2 a). Furthermore, the transmission heat loss related to the heat-transferring building envelope HT’ is 0.26 W/(m2 K). At the same time, the maximum value for transmission heat loss HT’ specified in Table 2 of Annex 1 of the Energy Saving Ordinance 2009 of 0.45 W/(m2 K) [I](please insert value) is not exceeded.[/I]
Kind regards

the depicted building envelope.

Ignoring building services engineering for now.

There are only a few who can really plan and implement cleanly in aerated concrete or perforated brick.
parcus schrieb:That may apply to small contractors with limited purchasing options, although I have experienced some unpleasant surprises regarding the calculated figures in offers in this sector; it seems that for small contractors the thickness of their order book determines the final price. I have encountered competitive offers from such contractors that were sometimes up to 30,000 euros below my offer, with supposedly equal or even better specifications. +/- 5,000 to 10,000 euros are normal for comparable specifications.
Many things require special solutions, which come at a price.
parcus schrieb:There are manufacturer-specific thermal bridge catalogs for this 😉 However, I am convinced that our specialists have the proper training. And a structural engineer, based on all experience, does not simply sign off on incomplete calculations.
Thermal bridges are created far too quickly, or the structural load limits are reached.
parcus schrieb:Mostly due to rigid or incorrectly executed connections = a defect. How fitting that possible cracks remain hidden behind ETICS facades 😉 I have worked with expanded clay aggregate blocks, sand-lime brick, perforated brick, and aerated concrete, and I know of no single-family house without hairline cracks.
There is also no masonry through which cracks develop faster.
Kind regards

Bauexperte20 Aug 2010 10:52Hello,
You should not generally assume that. According to all findings, municipal budgets everywhere are empty; for this reason, municipalities are selling off their prime assets (properties). There will still be affordable building land for years to come—especially compared to private sellers—so there is plenty of time to save up equity.
Kind regards
