Construction materials calculator for Netherlands
How many bricks, bags of cement, cubic metres of sand and square metres of roofing does a house in the Netherlands actually need? These quantities are computed from the way buildings are built here — 225 mm external walls at 110 units per m², 1:5 mortar, 1:2:4 concrete and a 25° roof — not from a global average. Quantities only: material prices move week to week, so pricing happens against your own drawings.

What these numbers assume
- —Footprint taken as a 15 m × 10 m rectangle (150 m²), 1 storey.
- —Wall height 2.7 m; external walls 225 mm, internal 115 mm — the NL convention.
- —Openings deducted at 15% of external and 8% of internal wall face.
- —Foundation taken 0.75 m deep — governed by a design frost depth of 0.6 m.
- —Wastage allowance of 5% applied to bricks, tiles and paint.
- —Low seismic risk assumed.
- —Normal wind loading assumed.

Take off my drawingsBuilding materials in Netherlands — frequently asked
How many bricks do I need to build a house in the Netherlands?
+
For a 150 m² single-storey house built the way houses are built in the Netherlands — 225 mm external walls at 110 units per m² — you need roughly 23,296 walling units including a 5% wastage allowance. Scale it from the table above for your own floor area.
How many bags of cement does a house need in the Netherlands?
+
About 313 bags of 50 kg cement for a 150 m² single-storey house, across mortar (1:5), concrete (1:2:4), plaster and screed. Mixes are the ones conventionally specified here, so the figure moves if your engineer specifies richer mixes.
How much sand and stone will I need?
+
Roughly 17 m³ of sand and a comparable volume of coarse aggregate for a 150 m² house. Order by the load and account for bulking and compaction — delivered volume and placed volume are not the same number.
How accurate are these quantities?
+
They are geometry-derived planning quantities from a rectangular footprint, so they are the right order of magnitude and internally consistent — good enough to budget and to sanity-check a supplier's list. They are not a measured takeoff of *your* plan. For that, upload your drawings and get an itemised bill of quantities measured to STABU / NL-SfB and priced in EUR.
Why are the quantities different from other countries?
+
Because the buildings are different. Wall thickness, block size, mortar and concrete mixes, foundation depth and roof pitch are all national conventions, and each one moves the quantities. This page is computed from the Netherlands profile specifically, not a global average.
