Self Build Van 2 – Design Specifications

For van #2 index, see HERE

Note:  Writing this late 2018, build will be 2020-21 – so this is very much ideas and draft!!!!

The Van2 project is different to the NV200 self build.  The NV was designed as a camping car with a 5 year lifespan to fit in with our plans then, which included long trips, but more in a campervan environment than motorhome.

Van2 is more of a longer term van, 10-15yr, geared for longer trips as a motorhome, for both summer and winter trips, beaches and snow, and probably to use as car#2 for some of its life, and for stealthy camping.

So size needs to be small, yet it needs to be fully featured to be a fully functioning motorhome

One key element is that we want bikes and snowboards to be internal to the van.

The spec below is a bit OTT, but yep, thats the plan!  This is a long-term-usage project so no expense or design element will be spared!

The design specifications


  • Ideally MWB L2 H2 van (L3 if needed)
  • (CAD based on floor area of Ducato, but not taking into account any ingress if bulk head, roof, walls, beams or door structures, or access to light fittings etc).  So very much draft and ideas stage!!

Furniture/Design considerations

  • Lightweight faced ply, or unfaced where not seen.
  • Mixture of wall linings, but all insulated, vapour barriered, and lined.
  • Site lines from Sofa area designed not to see a “solid bulk head” to give impression of more room
  • Kitchen area kept wide and open to give feeling of more room
  • Cab area not used, so easy to seal off for stealthiness and insulation,  Means less wasted floor area using cab seats, and should be cosier.


  • All LED, and mixture of spotlights, reading lights,  recessed strip lights, and even colour hidden ceiling moodlights
