New Build Information

New Builds are a specialist area & should only be undertaken by competent, qualified & experienced professionals.

They require the services of a professional architect to approve all surveys, investigations & to oversee employment of other professional services.

The specifications only apply to dwellings up to 2 storeys although some are additionally applicable to 3 storeys.

The design & construction of the proposed works is always the responsibility of the designer, applicant & contractor.

When using our specs, checks should be made to ensure that they apply to your specific project.

Additional factors requiring attention for New Builds:

  • SAP Calculations
  • Structural Calculations
  • Water Calculations.
  • Other factors. This is not a complete list.

Please note: Use of our specs does not guarantee approval.

Please see the "New Build Info" page.
