Swallownest
Swallownest's commercial plots sit where the A57 meets the M1, suiting trade portals and vehicle workshops with secure yards. We design, fabricate and erect these as one package.
Commercial Steel Buildings in Swallownest.
Swallownest sits against M1 Junction 31, where Rotherham's commercial south meets the Rother valley, and its trade parks and village workshops keep a standing need for steel-framed space. We design, fabricate to BS EN 1090 Execution Class 2 at our Rotherham workshop and install commercial steel buildings here with our own directly employed teams.

Accredited for design, fabrication and installation, with the paperwork to prove it.
- BS EN 1090 Execution Class 2, UKCA marked: the execution class your engineer's design legally has to be fabricated to.
- Coded welders, BS EN ISO 9606: every structural weld made by an approval-tested welder, traceable on the documentation.
- ISO 9001 quality management: a quality system audited end to end, not a badge on a footer.
- CHAS Elite, SafeContractor & ConstructionLine Gold: the pre-qualification pack your procurement team lifts straight into a PQQ.
- GBP 10m public and GBP 10m employers liability: published figures, because your procurement team needs them on file.
- Directly employed, CSCS-carded site teams: the people on your site are ours, not subcontracted, so one team owns the result.

Common questions
FAQs
Yes. Our fabrication workshop is at Hellaby, Rotherham, in the same borough, and our own design, fabrication and installation teams cover Swallownest, Aston and the villages along the S26 corridor.
Yes. The junction corridor draws trade counters, vehicle workshops and small distribution users that need 15 to 30 metre portal spans. We design the frame around racking, doors and yard circulation from the first drawing.
Yes. Kiveton's regenerated pit ground typically calls for piled foundations tied to the Coal Authority record. We detail column bases to the as-built pile layout and verify bases before steel goes up.
We design, fabricate and install the structural frame, with mezzanines, staircases and secondary steel as part of the same package, then stay available for the aftercare once you are in.
BS EN 1090 Execution Class 2 with UKCA marking, coded welders to BS EN ISO 9606, ISO 9001, CHAS Elite, SafeContractor and ConstructionLine Gold, with GBP 10m public and employers liability cover.
The footprint and eaves height, the site postcode, what the building is for, your target dates and whether you need installation as well as the frame. Drawings help, but a dimensioned sketch is enough to start.
