Good evening,
I am new here but occasionally follow some of the posts. A brief introduction: I am 26 years old, a tax consultant, and I live in NRW, near Cologne.
Next year, I would like to build a house on my own. I would be very grateful if you could provide feedback on my building project and whether it is realistically achievable.
The plan is for a house with an accessory apartment for my parents, without a basement. The total size of the house should be around 300 sqm (3,230 sq ft). It will have two full floors, and the attic will not be developed. Possibly a KfW 70 standard house.
Next year, I will have two months of parental leave. The plan is to complete the shell construction with two skilled workers and one layperson (myself). My first question is: is this achievable within two months?
Second question: is my construction volume realistic? I am planning total costs for the house and plot at about 400,000€ (approximately), with the land costing around 130,000€, leaving about 270,000€ for the house.
I estimate material costs at around 180,000€ (including heating, roof tiles, plumbing, etc.). The remaining 90,000€ is planned for skilled labor.
Additional information: Among my acquaintances, I know a roofer, a window installer, and an electrician, who will do their work for free; I only need to provide the materials. Furthermore, I have a contact who works at a large building materials supplier and will grant me a staff discount.
I would like to start in April (parental leave begins at the end of May) and ideally move in by October.
Are my plans realistic?
Thank you in advance for your feedback.
Best regards

At our site, a construction team of 4 to 6 people worked on the building, completing the shell including excavation, utility trenches, formwork for the concrete basement, and concrete ceilings in 7 weeks. It went really fast, but they were a well-coordinated team.
With so much self-construction involved, I would rather estimate the construction time as 1.5 years. Who knows when they will have time; you might need longer, and I also doubt that your friends will really work completely for free.
What you must not forget are the additional construction costs! (development, architect, land surveying office, building permit/planning permission, etc.) There is a separate thread where these costs are broken down.

nordanney13 Aug 2015 08:48Recalculate your figures. 300 m² (3,230 sq ft) of living space equals approximately 1,200 m³ (42,390 cu ft). Your uncle is supposed to pay €600 per cubic meter. That comes to around €720,000 for you.
For the outdoor areas, the landscaping contractor estimates about €80 per square meter of the plot (terrace, driveway, lawn, plants, edging stones, etc.). Unfortunately, this fits well with what we have experienced.
Does your common sense still tell you that €300,000 will be enough?

Johannes198813 Aug 2015 19:40Good evening everyone,
Thank you very much for all the contributions. I am really starting to realize that I have no idea about this topic. Luckily, there is this forum...! 🙂
Now I also see that I expressed myself somewhat incorrectly this morning; it’s really hard to write a proper post on a phone.
Let me briefly summarize some points for my understanding:
According to the Federal Statistical Office, the average cost per cubic meter of enclosed space in the calendar year 2013 was approximately EUR 274.
Using this table, I tried to calculate the enclosed volume. For a building footprint of 10m by 15m (33ft by 49ft), two stories without a basement, and no finished attic, I come to about 920 cubic meters (32,485 cubic feet) of enclosed space.
I find this figure somewhat low. I would have expected the enclosed volume to be around 1,100 cubic meters (38,832 cubic feet). This would result in costs of approximately EUR 301,400, excluding exterior landscaping, garage, additional construction-related costs, and land.
Of course, some amount of owner labor would reduce this, but perhaps only by about EUR 30,000 to 40,000.
Does this sound reasonable?
Best regards

1) A 10x15m (33x49 feet) footprint with 2 full floors corresponds to about 240-250m² (2,585-2,691 sq ft) of living space. So, roughly 50m² (540 sq ft) are still missing.
2) Since 2013 (statistics), prices have increased by around 15 to 20%. By 2016, the additional costs will likely be about 25%.

Johannes198813 Aug 2015 20:52Really, have prices risen that dramatically? Wow.
This just shows once again how little I know about this field. I had almost thought that I should be talking more about 300 square meters (3,229 square feet) of usable floor space. But the plan is for a house with a footprint of 10 x 15 meters (33 x 49 feet). Of course, I know that with this size you still have to subtract the wall thickness, etc.
