Start here: conversion planning

A workable conversion plan connects budget, weight, layout and the order of construction. Begin with the journeys you actually intend to make: weekend trips, longer holidays or living and working from the vehicle. List essential functions before deciding on finishes. A bed, ventilation, secure storage and usable cooking space have dependencies that affect the whole interior; adding them late can mean undoing completed furniture or services.

Create a simple measured drawing and keep the dimensions of your chosen equipment beside it. Check door openings, wheel arches, access to fixings and the space needed to remove a component for repair. Allow for insulation, lining and mattress thickness rather than working only from the bare shell. A cardboard mock-up can reveal awkward movement or an inaccessible cupboard before you cut expensive materials.

Use the public conversion-cost calculator to separate the base van, equipment allowances, paid labour and contingency. Replace its example figures with dated quotes and include delivery, consumables, tools and inspection. Record what each amount includes so that two apparently similar products or installation quotes are genuinely comparable. Keep a running weight budget next to the financial one; unused cash does not compensate for insufficient payload.

Start here: define the requirements and layout, plan openings and hidden services, then schedule insulation, lining and furniture around inspection access. Develop the electrical and water systems before closing their routes. Reserve time for specialist installation, checks and correcting findings, and do not tie the first test of a new system to an immovable departure date. Photograph hidden work and keep a change log. If a component changes, revisit every affected connection, mounting position and allowance. The articles below cover each decision in detail and link back to the relevant system guides, making this hub a practical route through the build rather than a deadline to copy.
