Local Groundworks

As groundworks are typically labour intensive, it can often be beneficial to appoint local contractors for this stage of the build and leave us to construct and assemble your Premium Steel Workshop. Many customers already have an existing base and only require footings. Every Premium Steel Workshop comes with full slab and footings plans with clear instructions and dimensions for you or your contractor to follow.

 For customers local to our stores in Bishop’s Stortford – Hertfordshire (within 25 miles), who would rather have every stage of the build taken care of by Steel Build Masters, we will be happy to offer a price for all your groundworks and arrange a full site survey to discuss your project in person.
