Domestic Polytunnels 12' (3.65m) Wide
Domestic Polytunnels UK
span>The 12‑ft width is deliberately chosen because it allows a central bed with growing space on both sides, which isn’t just convenient — it’s one of the most space‑efficient domestic layouts. This width hits the sweet spot where you maximise usable growing area without creating awkward dead zones.
🔧 Structural detail you might have missed
Every model listed uses 35 mm galvanised steel, which is thicker than many hobby‑grade tunnels. That diameter is typically used in small commercial tunnels, meaning these “garden” tunnels are structurally closer to light commercial units than most domestic kits.
