Why choose the adjustable frame

The adjustable frame is perfect if you have an existing hard standing area, or an old concrete pad. It is easy to assemble and can be put together by one person, therefore saving time and money on preparing the groundwork on an existing site. If you are starting from a blank canvas, you can either create a full concrete base to fully support the building, or construct 4 pads for the corners for the adjustable feet to sit on.

What groundwork is needed for the Box Office

The steel chassis can go directly onto an existing hard standing such as an old concrete pad or paving slab base. If it is unlevel – the chassis can be adjusted by up to 100mm, to ensure the frame is level.

If you are installing on a lawn – simply remove the top level of grass, and create four hard standing pads for the four feet to sit on. You will need to dig down by 300mm – then either fill with concrete / hardcore with a paving slab – or simply fill a bucket with concrete and drop into the hole. This can be easily removed in the future if required.
