Hello.

The approved building permit / planning permission for a 160sqm (1,722 sqft) single-family house is available, so I want to start planning the electrical installation first. Tomorrow, I will have the floor plans of both levels printed on A0 paper so that I can mark everything on them.

What should I keep in mind? This is not just about deciding which and how many switches and sockets should go where. What else do I need to consider?

Hello,


Then take notes/space and discuss the actual installation on site (during the shell construction) with the electrician.

Exactly – the electrician will mark your requirements on the walls so that his team knows where to place everything. Then he will provide you with an offer for the additional services.

- Plan for the future (considering current trends) – there is a clear move toward networked devices, for example, refrigerators – so it makes sense to plan for this in advance.
- Make a list of the existing or desired electrical appliances for areas like the kitchen, living room, and office. Go through this list to determine which devices will be used permanently (fixed outlets) and which only occasionally (a work outlet in the kitchen might be sufficient – in the living room, simply plugging/unplugging or a temporary power strip might work).
- Consider which devices you plan to purchase in the near future (2–3 years), for example, a surround sound system. For these, you should arrange for suitable preparations or outlet installations.
- Think about any additional comforts you would like, e.g., a central switch for electric blinds; KNX control systems.

Finally:
Budget enough funds. We allocated 1,500 euros plus funding for the satellite system for the additional work. Our general contractor said he had already included an upgraded electrical installation. When the electrician’s offer arrived, it was shocking (more than three times the budgeted amount plus the satellite system), and budget cuts had to be made. We successfully reduced costs further and had to abandon some requests (such as preparations for central control of the electric blinds).
Still, some might say we got a relatively inexpensive offer.
