Concrete Blockwork (140mm external / 90mm internal) is a building-planning choice included in the Price Your Build estimator. It can affect structural method, material quantities, insulation and detailing.
What this option means
Routes external walls to M140 concrete blockwork and internal partitions to M90 concrete blockwork.
Why it affects the estimate
The estimator uses this selection to apply an appropriate allowance. Actual requirements depend on the final design, site conditions, supplier selection and contractor scope.
Before proceeding
Confirm the wall build-up, structural certification, weatherproofing and service-routing requirements.
Compare the final specification and inclusions against quotations before appointing a contractor.
