Space Joists - Metal web floor joists

All our house kits and two-storey extensions are supplied with engineered metal web joists

(Eco Joists) for intermediate floors.


The open webs make it easier and faster for follow-on trades like electricians and plumbers to run services through the floor zone saving on the overall build cost.

Longer spans mean less internal load bearing walls are required helping to reduce foundation costs.
