These sturdy, demountable, relocatable buildings can comfortably remain in place for many decades. But without foundations they are technically 'semi permanent'.
These structures offer a far more permanent and clearly different design that meets very long term needs, or when facility performance must be higher. They make excellent warehouses, chilled storage, workshops, logistics buildings, factory extensions and assembly/production areas etc. Outstanding in service they will more than pay for themselves in a fraction of their lifespan. In comparison to 'temporary' our 'semi permanent' buildings:
These all-steel buildings are considerably more robust and whilst they have a higher initial investment level, they can often achieve the high specifications of a conventional building at a lower overall cost.
Whereas aluminium frame temporary buildings are more standard, 'off the shelf' quick turnaround products, semi permanent steel frame buildings are specifically designed. They meet regulatory requirements and structural engineering calculations are issued for each building. These buildings are custom made so entirely bespoke sizes and even odd shapes are no problem.
These are heavier weight buildings and will take longer to construct than temporary but nowhere near as long as a conventional build.
These buildings require more work on site than their temporary cousins, but the end result is a much more robust and accommodating structure.
Steel sandwich panel exterior buildings can come with a “no leak guarantee” unlike their temporary building counterparts, which are weatherproof but due to having PVC roofs and the fact they just sit on an existing hard surface, can’t be guaranteed waterproof.
Wall panel thickness, type and composition can be varied to suit the application, customer, landlord, compliance and insurance needs, e.g. LPCB standards requiring highly fire resilient cladding.
These buildings can be supplied with roofs with high levels of insulation unlike the PVC roof alternative, which is not as thermally efficient. This saves on running costs and meets any temperature care standards which need to be adhered to.
These buildings are well suited to sites where harsh weather conditions prevail, such as windy, coastal, off shore or higher altitude locations. As a comparison aluminium frames are usually only recommended to 100m above sea level.
The general rule of thumb is the less ‘temporary’, the more ‘proper building’ options you can have e.g. skylights, solar panels, fire sprinklers, HVAC, fume extraction, air purification etc.
Already achieving far higher Wind Return Periods (WRP) than aluminium frame buildings, these buildings can be designed to support weighty internal and/or external fixtures & fittings.
