How do you want your future home on wheels to look?

The transformation starts in your mind:

Dare to try and take the first step

Before you grab the jigsaw and start cutting into your van, take a moment to pause and breathe.

Planning is everything, there’s a lot to think about: electrics, water, storage, and yes, where the coffee maker should go! In this section, you’ll get an overview of everything from layout planning to the small details that make a big difference.

Here’s where you decide on lighting, storage, and how to make the most of your space. This is your chance to add your personal touch, but be careful not to get lost in the details.

Personally, I’m great at getting lost in the details myself. I once spent hours choosing the perfect handle for a kitchen drawer in my first van. It mattered, sure, but it didn’t make or break the project. It’s easy to get stuck fine-tuning when the real goal is to get on the road and enjoy the journey.

Your results might not turn out exactly as planned, but your effort will take you further than you think.

Learn everything from electrics and insulation to shaping a kitchen worktop

Build your dream campervan with smart, long-lasting and safe solutions that make life on the road comfortable.
Always start with a plan: decide on key functions, sketch your layout, and prioritise insulation, electrics, and ventilation before you start installing furniture. Getting the order right saves time, money, and headaches later on.

Here you’ll find in-depth guides on calculating power consumption, battery sizing, wiring diagrams and much more, all based on real experience and practical solutions.

FAQ – Common Questions and Tips

What’s the best insulation for a campervan and how thick should it be?

Choose materials based on weight, moisture resistance, and ease of installation. Popular choices include XPS/foam boards, PIR, and wool. XPS offers good moisture protection and needs less thickness; wool breathes and helps regulate condensation. For Nordic-like climates, 20–40 mm XPS/PIR in walls and 30–50 mm in the roof usually works well. Add an air gap behind panels for better moisture control.

How do I safely install electrics, batteries, cables and fuses?

Start by planning your energy budget (all appliances × hours = daily Wh). Choose suitable batteries (AGM or LiFePo₄ depending on weight and budget), use correct cable sizes for 12 V systems (measure round-trip length), and fit fuses close to the battery. Add a shunt or battery monitor for control and ensure inverter and chargers have enough ventilation.

How can I design my electrical system for future upgrades?

Build with expansion in mind: leave spare cable runs, oversize your fuse box slightly, use modular DC distribution blocks and a central data hub (CAN or Victron Smart) so you can later add solar, more battery capacity, or a larger inverter without rewiring.

What should I consider when fitting wall panels or fixing cabinets?

Attach cabinets to structural framing or through the floor/vehicle frame rather than just thin wall panels. Use panel materials strong enough to hold screws and resist vibration; a thin plywood backing behind decorative panels improves fixing strength and long-term durability.

How can I reduce weight and keep strength in my furniture build?

Use sandwich constructions. A thin plywood or frames with lightweight cores (like XPS or honeycomb panels). Keep heavy items low and close to the vehicle’s chassis to maintain centre of gravity. Build in modular sections for easy maintenance and future adjustments.

Which flooring is best for a campervan: laminate, vinyl or wood?

Vinyl is ideal against moisture and easy to clean; laminate gives a stylish look and good durability but needs insulation or levelling beneath; plywood is great as a sub-floor for fixing furniture. Install flooring last or ensure fixings allow for slight movement to prevent buckling.

How do I install a roof vent or window without rust or leaks?

Pre-drill corners, use masking tape for clean cuts, remove burrs and metal shavings, treat edges with rust protection, and seal with a flexible marine-grade sealant. Measure carefully and follow sealing instructions to prevent future leaks.

How can I ventilate my campervan to avoid condensation and poor air quality?

Combine a roof vent with an extractor fan for active airflow, and position vents or windows for cross-breeze. Proper insulation, vapour control layers and a ventilated air gap behind panels help manage humidity and prevent condensation while cooking or sleeping.

What’s the best way to prevent moisture entering through seams and joints?

Use layered sealing: rust protection, flexible sealant, and an exterior trim or cap strip. Combine with mechanical barriers such as edge trims or flashing. Include hidden ventilation channels behind panels for dry-air circulation and easy inspection without dismantling the walls.
