ᐅ Experiences with Construction Companies in Berlin and Surrounding Areas (within approximately 50 km)

Create an Excel spreadsheet listing all the trades, from earthworks, construction access road, structural work, up to wallpapering, terrace, moving, paving paths, fencing system. Enter your planned quotes from the suppliers and compare them. During the construction phase, we also recorded the invoices there, so now we have a very accurate understanding of our costs. For example, electrical work: planned budget was 7,000€ (about 7,000 dollars), our preferred version came to 15,000€ (about 15,000 dollars), and upgrading to KNX automation can increase that to 50,000–100,000€ (about 50,000–100,000 dollars). The 30,000€ (about 30,000 dollars) difference reflects quality and scope — this is not a lottery win to be spent multiple times. Have fun planning and comparing. Regards, Nida35a

- 12,000 Smarthome (Somfy)

Is this an additional charge or the total price for the electrical work? And what exactly is supposed to be "smart" there? Number of users, etc.?

Briefly, what I have kept:
Control via touchscreen and app:
- Underfloor heating
- Alarm system (including information about window/door openings)
- Compatible with Google and Alexa
- Operation/monitoring of the roller shutters
It’s basically an "add-on module." If it fits within the price, I will look into it further.

Did you receive a scope of work document? It usually contains the key details.

The key points are usually included there.

I received one for the construction of the bungalow, including which systems will be used. It depends on whether you want to build to KFW 55, 40, etc. The scope of work for the bungalow is 20 pages long. Among other things, it included the following:

- Ground slab (including waterproof concrete, with a 22cm (9 inch) thick capillary-breaking layer of gravel-sand mix underneath)
- Exterior walls (24cm (9.5 inch) hollow bricks + 12cm (5 inch) insulation + 2cm (0.8 inch) plaster)
- Windows (fiberglass; certified for passive houses; manufacturer Brömse)

The following sections were described in the scope of work "The Bungalow":
1. General
1.1 Notes
2. Building planning
3. Shell construction
4. Roof structure/woodwork
5. Roof covering
6. Façade – General description
7. Dry plaster
8. Main entrance door/windows
9. Electrical installation
10. Heating/plumbing
11. Interior plaster – General description
12. Screed – General description
13. Tiles
14. Interior doors
15. Natural stone work – General description
16. Entrance stairs – General description

What are the crucial points one MUST pay attention to?

Yes, I’m familiar with the device. It costs 300 euros. An extra 12K is quite steep. Sure, there’s more included like the “fancy” touchscreens and so on, but still.
