Yes, with slight modifications this is possible.
What is the maximum/minimum size for a Stormie?
While there is no technical limit to the maximum or minimum size of a Stormie, we recommend a build of between 5 and 9 metres.
Stormies under 5 metres are not as cost effective to build. Stormies over 9 metres will require extra mechanical ventilation to prevent overheating.
Will the polycarbonate turn yellow?
