The Wall Upgrade Lightweight Block Internal Leaf Estimating Calculator estimates the materials and labour required to add a blockwork inner leaf to a single skin wall, as is often required when converting a garage into a habitable space.

To estimate the upgrade of a single skin wall with a lightweight block internal leaf, first review the dimensional information and estimating options, including whether a DPC is required above slab level. Please note, this estimating calculator assumes the internal leaf will be built straight off the existing slab.

The combination of information taken from the specification and the dimensions you enter will be used to calculate the following items:

  • Blockwork and coursing blocks
  • DPC
  • Cavity insulation
  • Plastering and rendering
  • Skirtings
  • Decoration
  • Plus all labour associated with the above

This Estimating Calculator is linked to the Specification.
