Wandi Granny Flat Construction – Granny Flat Drainage and Concrete Levels

Granny flat concrete needs to be coordinated with the building plans, engineering, services and access. In Wandi, Santa Concrete can assess strip drains, pits, slab falls, stormwater transitions and low-point corrections.

The quotation can cover demolition and earthworks through to the completed slab, paths, patio areas and external access concrete.

Any changes to the dwelling size, wall layout or engineering can affect concrete quantities and the construction scope.

The finished floor level needs to work with stormwater movement, door thresholds and the relationship to the main dwelling.

Rear-yard projects may require temporary fencing, protection of paving or landscaping and a defined washout location.

The project should be planned around finished floor levels, water movement, nearby buildings, drainage outlets and slab transitions. Changes to plans or engineering should be reviewed before concrete quantities are finalised.

Pricing is more accurate when engineering, earthworks, pump access, service penetrations and external concrete are clearly identified.
