Low / Conservative (Smaller standard windows) is a building-planning choice included in the Price Your Build estimator. It can affect window and door allowance, solar gain, shading and thermal performance.
What this option means
Sets glazing calculation by window area; frame material is selected separately. Sets glazing calculation to evaluate windows at 10% of external walls.
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 glazing areas, orientation, ventilation, shading and any energy-compliance requirements.
Compare the final specification and inclusions against quotations before appointing a contractor.
