Planning & design
We help with planning applications and design your building around the job it has to do, the site and your budget.
Our servicesBS EN 1090 accredited
CE accredited since 2014, so every frame we fabricate is certified structural steelwork, made in our own workshop.
About JSLBuilt by our own team
From the first drawing to the last sheet of cladding, the same family team fabricates and erects your building.
Our buildingsA family trade,
handed down
JSL Construction began with blacksmith George Leake, working iron for the farms around Ripon. The trade passed to John Stanley Leake, then to David Leake, and today David runs the business alongside his son Mark — the fourth generation of the family to work steel in North Yorkshire.
That history is why customers still deal directly with the people making their building, and why we would rather do one job properly than three in a hurry.

“David and Mark were very helpful and patient while my agricultural building went through a number of specification changes. I'm extremely happy with the final building and would recommend JSL Construction to others.”
