Building your own campervan is rewarding, saves money, and gives you exactly what you want. Here's what you need to know.
Essential Skills for Van Conversion
Carpentry
The foundation of most van builds:
- Measuring and cutting accurately
- Using a jigsaw for curved cuts
- Drilling pilot holes
- Basic joinery (battens, plywood sheets)
- Fitting hinges and catches
Electrical
Van electrics aren't as scary as they seem:
- Basic circuit theory (voltage, current, resistance)
- Wiring 12v systems (LED lights, sockets, fans)
- Installing a leisure battery

Plumbing
For kitchen and shower systems:

Insulation
Critical for UK van life:
