This guide will show you how to turn an empty van into your ideal home on wheels — whether you’re keeping things simple or gearing up for full off-grid adventures. Skip the endless searching and guessing by following our tried-and-tested product recommendations, or choose one of our ready-made bundles for a smoother, cost-effective start. Select your budget, choose your setup, and get ready to hit the road.

When you order a bundle, you’ll receive a ready-to-go basket of high-quality materials — carefully selected and pre-packed in the exact quantities needed for your van model. No more overbuying, underbuying, or wondering whether something will fit.

To make the build journey simple and stress-free, we’ve organised this guide into clear phases:

Before you begin

Before You Begin: Plan First

Before you buy or strip your van, plan it properly.

Changing things later is costly — map everything out first.

Decide how you’ll use your van (weekends, full-time, off-grid) and shape your layout and budget accordingly. If you can, use a tool like SketchUp to visualise:

- Bed (fixed or convertible)
- Kitchen & appliances
- Bathroom/toilet setup
- Storage
- Lighting, sockets & wiring runs
- Plumbing & gas routes
- Windows & roof vents
- Seating/bulkhead (keep for noise vs remove for space; add swivels)
- Solar, batteries & off-grid systems

Get inspiration: browse real builds and storage hacks on our Instagram @campervanshop to spark layout ideas.

If you plan to reclassify as a motorhome, review DVLA criteria in advance (windows, access door, exterior features, and fixed internal features like seating/table, bed, cooking, storage). Photograph these clearly during the build and reference them in your DVLA cover letter.

Preparation
With your design locked, strip the van back — remove bulkhead, panels, flooring — for a clean slate. Check for rust, sand, treat, and protect exposed metal with primer/paint. Not glamorous, but essential for a dry, long-lasting build. Now you’re ready to order your first bundle!

Phase 1 – Foundation

Phase 1 – Foundation

Phase 1 is where your transformation begins—preparing the van’s interior shell and laying the foundation for everything that follows. This is where a bare metal shell becomes a warm, quiet, comfortable living space. Take your time — a solid start means a cosy, efficient van later.

What Phase 1 Includes

  • Sound deadening to minimise road noise and vibrations
  • Insulation for temperature control, energy efficiency, and condensation control
  • Carpet lining for comfort and aesthetics
  • Flooring — insulation, subfloor, and finish
  • Wall & ceiling cladding for a clean interior and hidden services

Note: Most electrical wiring (Phase 3a) and plumbing (Phase 4a) should be installed before full insulation & cladding. Some external hardware (Phase 2) also needs fitting before lining goes on.


Sound Deadening

Sound deadening reduces road noise and vibration. It also improves comfort and sleep while adding minor thermal benefit.

Best Materials

  1. Butyl sheets – stick directly to metal to stop vibration
  2. Acoustic foam – absorbs internal noise & echo
  3. Thermo Liner – reflective thermal + some acoustic control
  4. Acoustic sealant & foam tape – stops rattles and leaks

How to Install

  1. Clean all metal
  2. Apply butyl sheets (~60% coverage)
  3. Add acoustic foam / Thermo Liner
  4. Seal gaps & joints with acoustic sealant & foam tape

  • Thermo Liner
  • Green Glue Acoustic Sealant
  • Norseal Anti-Vibration Tape

Insulation

Correct insulation prevents heat loss, reduces noise, stops condensation & protects from mould/rust. It’s one of the most important steps in your build.

Best Materials

  1. Reflective insulation — radiant heat control
  2. Foam board — high R-value on flat surfaces
  3. Thermo Van Liner — flexible, adhesive thermal layer
  4. Dacron loose-fill — fills gaps, won’t absorb moisture
  5. Spray foam — high efficiency, pro install recommended
TypeMaterialR-ValueProsCons
ReflectiveFoil w/ air gap1.0–3.5Light, moisture-proof, cheapNeeds air gap, weaker in cold
Loose-FillDacron / wool3.0–4.0 / inchGreat in gaps, sound-absorbingCan settle over time

Foam BoardXPS / PIR3.6–5.0 / inchExcellent thermal valueHard to shape around curves
Spray FoamPU6.0–7.0 / inchBest performance, seamlessExpensive, hard to modify

Insulation Steps

  1. Prep & rust-treat metal
  2. Apply sound deadening
  3. Install Thermo Liner
  4. Pack cavities with Dacron
  5. Fit battens (leave space for wiring)
  6. Add lightweight ply (3–6mm)
  7. Carpet or clad
Layer order: Metal → Butyl → Thermo Liner → Dacron → Battens → 3-6mm Ply → Carpet/Cladding

Carpet Lining & Cladding

Carpet Lining

  • Ideal for curves & complex shapes
  • Warm & quiet
  • Budget friendly

Wood Cladding

  • Beautiful cabin look
  • Best on ceilings & flat walls
  • Needs battens

Best Combo

Carpet the awkward bits, clad the visible bits.

Install Carpet

  1. Clean surface
  2. Cut oversize
  3. Spray adhesive both surfaces
  4. Apply & stretch
  5. Trim clean edges

Flooring

Your floor must be strong, insulated, quiet & moisture-proof.

Floor Layers

  1. Optional: Butyl pads
  2. Gold Underfloor Insulation
  3. 9–12mm plywood
  4. Underlay if needed
  5. Your finish

Flooring Options

  • Vinyl sheet: light, waterproof, seamless
  • Vinyl click planks: premium look, heavier
  • Laminate: cheap, not moisture-friendly
  • Engineered wood: beautiful, heavy, seal well
  • Rubber coin: best for gear vans

Phase 1 Summary

Phase 1 transforms a bare shell into an insulated, quiet, comfortable living space. It supports all later systems. Plan wiring, plumbing, and windows before closing walls.

Done right, this stage sets the standard for the whole build.
