I have browsed through several posts here in the forum and contributed occasionally. Today, I would like to take the opportunity to post a kind of diary about our project, ultimately to look back on the whole thing in the future and see what could have gone better – for my own learning experience.
We will be building in Saxony, near Dippoldiswalde (22 minutes and 19 km (12 miles) from Dresden). We currently live in a rental apartment in Dresden. Our workplaces will remain in Dresden; working from home is planned about 1-2 days a week. It is also worth mentioning that our child lives with us, and my two older children from a previous relationship occasionally stay overnight.
We found the plot at the end of 2021; the listing had been online for a few months at over €165,000. No one really wanted it because the 3,100 m² (33,365 sq ft) plot includes a protected biotope (an old meadow orchard) in the back, which cannot be built on. Additionally, there is a separate owner to the left, right, and in the center. We have what is basically a servient plot with easements (water, electricity, etc.). Since I tend to be optimistic and see this as an opportunity, we just had to have it. In the end, after negotiations, we bought it for €130,000, which personally I consider a bargain. The owner of the neighboring property (one house on the left, one plot with a bungalow on the right) is already 86 years old and in assisted living. We have already discussed a possible exchange or purchase with their successors at some point in the future.
Our general mindset is simple. Everything can be standard, functional, and serve its purpose. We do not like to spend extra money on things that only look good (like paint). I also buy and collect many items for the house and plot via local classified ads, especially for garden design right now—there are many giveaways 🙂
I really enjoy managing and planning the project and handle about 99% of the arrangements. My girlfriend fully trusts me in this. It is definitely an advantage and very relaxing not to have to discuss every single tile choice. Also, I make decisions quickly. We are building with Heinz von Heiden because I believe the price-performance ratio is good here. What the end result will be remains to be seen, but considering that they have built 50,000 houses, there is trust.
No official zoning plan. Building according to the surrounding development since it is a village. Mixed-use area, open development according to Section 34, Paragraph 1.
Plot size: 3,152 m²
Slope: 5%
Number of floors: 2 full stories
Roof type: gable roof, 25 degrees
Style: country house
Orientation: terrace facing northwest
Additional requirements: From the sewage operator: cistern (an old but good 3-chamber septic tank already exists and will be used)
Client Requirements
Basement, floors: no basement, 2 full stories
Number of people, ages: 3 (M: 36, F: 36, Child: 3)
Space requirement on ground and upper floors: 80 m² (860 sq ft) each
Office: family use or home office?: yes, an office/hobby room upstairs
Guests per year: occasionally, hence a guest room and shower bathroom on the ground floor (also in case one cannot go upstairs with age)
Open or closed architecture: ground floor rather open, upper floor closed
Conservative or modern style: mixed
Open kitchen, kitchen island: open kitchen, no kitchen island
Number of dining seats: 12 (the table is already owned, so no kitchen island)
Fireplace: planned, but the builder wants €6,000 for a masonry fireplace in the center of the house, which I find expensive. I want to install a stainless steel fireplace on the exterior wall myself.
Music/stereo wall: less important
Balcony, roof terrace: no, poor cost-benefit ratio given the large plot
Garage, carport: steel garage 6 x 8 m (20 x 26 ft) with gable roof, 3.30 m (10.8 ft) high and with electric door for the man of the house :p
Useful garden, greenhouse: not important for now
Other wishes/peculiarities/daily routine, including reasons why something should or should not be done: my major wish is definitely a fireplace, but it must be room-air-independent because the house has KfW55 energy standard. I am hoping to get some advice here in the forum on retrofitting a stainless steel chimney.
House Design
Who planned the design:
- Planner from a construction company: Heinz von Heiden prefab house C630 (The Immutable)
- Architect: Heinz von Heiden
- Do-it-yourself: painting and flooring, tiling, excavation, landscaping, and utility earthworks
What do you particularly like? Why?
We especially like the open area comprising entrance, living room, and kitchen with a glazed front facing the garden. The floor plan convinced us immediately. And of course, the space with 160 m² (1,722 sq ft). We currently have 91 m² (979 sq ft).
What do you dislike? Why?
It is rightly called "The Immutable," as walls cannot be changed. But it was €30,000 to €40,000 cheaper because of that.
Price estimate according to architect/planner: fixed-price contract signed in February with 15 months price guarantee:
~€260,000 including special features (standard: ~€235,000)
Included: air-to-air heat pump with storage, large controlled ventilation system, electric shutters on ground and upper floors, underfloor heating on both floors, all materials except tiles, floors, and walls
Preferred heating technology: air-to-air heat pump – not changeable
If you have to give up any details or extras:
- You can forego: upper full floor, large controlled ventilation system, electric shutters, photovoltaic (preparation only)
- You cannot forego: fireplace, 6 rooms
Why is the design as it is?
Standard design from the planner?
Yes
Which wishes were implemented by the architect?
Changes to windows and access to the master bathroom through the bedroom
What makes it particularly good or bad in your opinion?
Open design, large and sufficient rooms
Financing
Through our local savings bank. The plot is still variable at 1.8% interest, and the house loan for 15 years also at 1.8%. Equity is about 17%. Monthly payments should be around €1,380.
Construction costs per m² without additional building costs: €260,000/160 m²: ~€1,625/m²
Construction costs per m² including additional building costs: €322,000/160 m²: ~€2,012/m²
Plot cost without additional costs: €130,000/3,152 m²: €41.24/m²
Plot cost including additional costs: €147,000/3,152 m²: ~€47/m²
As mentioned, I am writing this primarily for myself as a "diary" to document everything in writing. Maybe it will also be included in the construction folder that I keep very meticulously – accountant mode 🙄 😀 I am always grateful for suggestions, opinions, tips, but also critical feedback as food for thought. Questions will certainly arise over time. You find a lot on the internet and other posts.
I am open to questions about the house, costs, builder, etc. anytime.

hanghaus202310 Mar 2023 12:26Is that written like this in the contract? It doesn’t make sense to me.

Oberhäslich10 Mar 2023 12:44Yes, that's correct, I need to make a correction. We have a different scope of work due to the self-performed tasks. The original version from the initial consultation included excavation of 30cm (12 inches) and compacted gravel with a 1m (3.3 feet) perimeter. Although I find that odd because Heinz von Heiden assumes a 2m (6.6 feet) perimeter. Also, in hindsight, I think the €2500 credit is really too low. I also contacted the civil engineering company that works for Heinz von Heiden, and they want over €1000 just for the site setup, and a total of about €12,500 excluding gravel. Well, the quote also includes some crane space and parking spaces, but with their offer, I end up with over €15,500 including gravel. And we only need to excavate or fill 20-30cm (8-12 inches) more.

hanghaus202310 Mar 2023 12:47That's how I pictured it. Exactly the contractual content to be read that is omitted.

WilderSueden10 Mar 2023 14:02That makes sense. The profit stays with the company, and the client gets a portion of the costs reimbursed 😉

Oberhäslich10 Mar 2023 14:15And when the additional costs come up, you may have to pay an extra 12,000 to 13,000. Still, it is cheaper if you manage the contracting yourself. This way, you save about 4,000 to 5,000 €.
I did some calculations. For 30cm (12 inches), you get roughly 40m³ (52 cubic yards) of excavation and 70t (77 US tons) of gravel. Just the gravel alone would cost around 1,250€. Another 1,250€ would go towards setting up the construction site, storing materials on the side, and bringing in/compacting/leveling the base.
The original question about whether billing is done by hours or quantity is mainly because I wanted to know if anyone has had a similar experience. It would be interesting to find out how long an earthworks contractor typically takes for excavation and foundation work.

He can more easily cheat on the hours, although the time estimate is already quite generous. I believe our excavation contractor back then took three days for the foundation pit and the final grading. I might be mistaken; it could have been a week. However, the excavation was 1 meter (3.3 feet) deep and the backfill was 1.2 meters (4 feet) high over an area of about 120 m² (1,290 ft²).
For quantities, you get weighbridge tickets as proof.
I would also recommend this approach for the neighbor.
