Digital Building Components offsite saves 10–20% on overall cost and improves installation efficiency by 20-30%

Offsite manufacturing is 50% faster than traditional methods

Modular construction can reduce the energy used in the

construction process by 67% and waste produced onsite by

between 70% and 90% in comparison with traditional

construction methods

Using more technology we could cut energy use, create highly-skilled jobs and build a new export market

Key Drivers

Suitable for:

• Specific buildings

• Development plots

• Masterplan phases

• Standardised product/platforms
