Building a 1,000 m² net house

A good net house is the foundation for every IoT system that follows. This guide is for owners who want to supervise a contractor or build with a local crew. Market reference costs for net and film houses run about 150,000–350,000 ₫/m² depending on size and materials.

Steps

1. 1

   Choose and level the site

   Pick high, flood-free ground near water and power. Level with a 0.5–1% slope to drains. Orient bays north–south for even light.

2. 2

   Set out and pour footings

   String out the column grid (often 4 × 8 m). Dig 40 × 40 × 60 cm holes, pour grade-200 concrete, set columns or anchor bolts.

3. 3

   Raise the frame

   Fit columns, trusses, purlins and diagonal bracing at the gables and centre. Check plumb with a level before tightening.

4. 4

   Stretch netting and fit doors

   Stretch net on a calm morning and lock it into the channel. Fit a double-door airlock so insects don't follow workers in.

5. 5

   Prepare for IoT

   Leave buried conduit to the control cabinet, a 4–6 m gateway mast and a bracket for the climate station mid-house.
