Agree the base arrangements
Your building needs a suitable base. What is included depends on the range and your quotation, so confirm who is preparing or installing it before you book other work.
If you are supplying the base, it must be solid, level and at least the size of the building's footprint, with the final requirements agreed for your project. Allow at least 1ft around the base and completed building for installation, inspection and maintenance, together with the necessary roof clearance.
Tell us about known underground services and any difficult ground conditions. A ground screw solution still depends on site suitability; photographs alone cannot confirm what lies below the surface.
