ᐅ Doing Your Own Electrical Work in a New Build

Hello, I have a question. We are planning to build a house, specifically a prefab house from Massa Haus. We have heard that the electrical installation package offered by Massa Haus (upgrade package) does not include the highest quality components. So, we thought about finding an electrician who could sell us the materials directly, which is not that easy.

During our search, we came across a company in Karlsruhe (we are building in Pforzheim) that offers electrical material packages along with consulting for the electrical installation. It is important to us that we do not receive any “no-name” components that we would have to replace later.

This sounds to us like the same principle as an upgrade package: we get the materials, instructions for installation, and possibly assistance during the process.

What would you choose? The upgrade package from the house manufacturer or branded quality from a specialist company at similar prices? We asked for quotes from both, and the prices are comparable.

Maybe someone here has experience with this.

Thank you in advance for your advice.

We will also do the electrical work ourselves, but with support and guidance from our electrician. He will create the electrical plan and then mark on the shell construction where we need to chase the walls and drill holes for the boxes.
We will probably be able to plaster over the conduits ourselves as well. Later, together with him and a few helpers, the cables will be pulled into the conduits.

However, the connection and wiring will be done by our electrician, as we wouldn’t feel confident doing that ourselves. He will also handle the warranty.

It depends on how quickly you want to move in and how much you feel capable of doing. Of course, it takes much longer, and you probably need to be quite diligent to stick to the schedule set by Massa Haus.

Hello!

I did the electrical work together with a certified electrician. I should mention that I trained in an electrical profession long ago and became an electrical technician, but nowadays I work in software.
We wanted to install home automation, which the electrician didn’t want to do alone, as it was new territory for him.

Anyway, here are a few points to keep in mind from my perspective:
- Don’t underestimate the time involved! Professionals are faster… and often neater.
- It takes time to acquire the necessary skills. (e.g., embedding switch boxes perfectly flush)
- Lack of expert knowledge means you’ll need access to specialists. (e.g., Where should the cables run?) So a lot can go wrong due to inexperience… resulting in double work.
- Missing or inadequate tools… A standard drill for home use is very different from a precision Hilti.
- Physical work! Sitting all day at a desk is a totally different experience…

Despite all that, it can also be fun to spend some limited time “working on site.” :-P

Cheers, torsan

For electrical work, only the preliminary tasks might be feasible for a homeowner to do, and even then only under the guidance of a qualified electrician. The zones and depths for laying cables are predetermined. Questions already arise at this stage, for example regarding structural integrity if the chases are cut incorrectly, and regarding the equipment required (usually, one does not have a wall chaser at home). Simply laying the cables into the chases is challenging. Connecting (each wire, each socket) must be done by the electrician, who must also check any cables that were installed by the homeowner.

The question then is what savings are possible in a timber frame construction and what the balance is between learning/training time and actual work time.

The milling machine is provided by the electrician, and we only need to purchase the milling disc.

Yes, there are always ways and means... however, the electrician is usually faster anyway...
