When to use this service

We will work with a structural engineer to check whether your chassis design meets the structural requirement of building regulations in the UK. They will also provide capacity limits and requirements for your foundations designer.

Use this service if:

  • Your project is located within the UK.
  • You have already prepared a chassis design using standard WikiHouse Skylark blocks.
  • Your design has 2 storeys or fewer.
  • Your design includes lateral walls every 5.5m or less.
  • Your design does not include any double-height spaces, except over a staircase.

If your project lies outside these parameters you will need to find a structural engineer.

What you will get

  • A report from a structural engineer which you can give to your building inspector.
  • A summary of loading capacity limits and foundation load requirements.

To use this service you will need:

  1. A structural engineer will produce a set of calculations to check your design.
  2. If the design meets requirements, we will send you the engineer's reports.
  3. If it looks like changes are needed to the design, we will contact you to share the engineer's findings. You can then pass these to your design team, or engage us to make changes to the chassis (under a separate fee, to be agreed at the time.)
