Detached houses
Electrical design for detached houses
A new detached house, semi-detached house, holiday home or a larger renovation: I produce an electrical design that a contractor can build as drawn and that is ready for future needs such as solar PV, a home battery and EV charging.
In short: TechDocuments Oy designs electrical systems for detached houses from Espoo and Tampere, for sites across Finland: detached and semi-detached houses and holiday homes, main board and circuits, plus provisions for solar PV, a home battery and EV charging. Low voltage up to 400 VAC.
Design scope
- Connection and main switchboard sizing (3-phase 400 V)
- Circuits and sub-distribution boards
- Lighting, sockets and interfaces with building services
- Provisions for solar PV and a home battery
- EV charger provision and load management
- Attachments for the building permit and network operator when needed
Deliverables
- Electrical layout drawings
- Switchboard diagrams
- Electrical description
- As-built drawings on request
Why a proper design pays off
A well-prepared electrical design makes contractor quotes comparable, reduces changes on site and already includes provisions for solar PV, a home battery and EV charging. Our background is in contracting, design and risk management, so designs are made to be built. House manufacturers and builders from abroad are welcome too.

Frequently asked questions
Do you design the electrics for a detached house?
Yes. We design the electrical installation for new detached houses, semi-detached houses and holiday homes: main fuse and main switchboard sizing, circuits, lighting and sockets, plus provisions for solar PV, a home battery and EV charging. The contractor receives clear drawings and switchboard diagrams.
Do you design solar PV, home batteries and EV charging for detached houses?
Yes. Solar PV, a home battery and EV charging can be designed as one package so that the main switchboard, protection and metering are sized correctly and the information the network operator needs is ready.
