Measure twice. Plan once.
A measured sketch becomes a material list. Start with a slab or a simple block wall.
The drawing explains the dimensions; it is not a construction plan.

Measurements and assumptions
Slab: length × width × thickness (meters). Wall: (length × height − openings) ÷ block module area. Waste is applied once, then blocks are rounded up.
Quantity estimate only. No reinforcement, mortar, foundations, mix design, delivery minimums or structural verification included. Confirm dimensions and specifications with your project professional before purchasing.
