For quick, cost-effective & robust onsite facilities, temporary or long term

PVC Roofed BigBox Temporary Building

Considering cost & speed, the standard achieved usually far exceeds expectations...

Pictured here is what we consider 'compromise insulation'; it's the best achievable with a "temporary building" - you need our all-steel fully insulated/sealed buildings for a higher standard. And yet this standard design with its double skin PVC (inflated) roof and steel sandwich panel walls protects well against temperature swings and condensation. Free-standing industrial outbuildings or linked to existing buildings, the effect achieved is usually a pleasant, welcome surprise.

This setup is a good choice as an insulated workshop shed or higher standard than the tent storage 'large metal shed' you can see below (PIR filled composite panel walls here changed for single skin cladded steel there); it's still quick & cheap but achieves a better work or storage environment and is easier / more effectively sealed at ground level.

Sometimes our honesty costs us a sale, but we don't have disappointed customers and the weaknesses of this building type are common to all providers... whilst it's often an advantage that these can be just installed straight on to an existing hard-standing (no ground-works usually needed), that's usually a two-edged sword, so we make sure everyone is clear about the risks of ground-level water ingress (and the ways to avoid it, which we offer as an option beyond regular sealing). We don't need foundations or even concrete, but we do pin or bolt, as deeply as structural engineering calculations specify to properly comply with Buildings Regs.

Ideal ambient storage solutions

PVC Roofed BigBox Temporary Building

Called "temporary", they rarely are...

A temporary building can be installed for a set period of time, e.g. during a renovation, but the reality (despite the name) is they're usually in place for many years, even decades, such is the robust design & life expectancy. Some call exactly the same structures "semi-permanent" simply as they outlive the perception of temporary (but we prefer to keep our definitions more distinguishable). Apart from a short lead time and quick installation, they are easily relocatable, tolerant of poor surfaces and don't require preparatory ground-works (we can install on a broken, uneven, sloping surface if you really want!)

Hence the description is subjective, meaning different things to different people, e.g. simply a quick storage shed or cheap industrial storage unit for most businesses, whereas for councils and Planning permission 'temporary' usually means <28 days usage (or 3m sides, <200m2 & >5m from closest boundary to qualify for Permitted Development and hence avoid Planning Permission). To us “temporary” means a lightweight structure, i.e. with a PVC roof, as opposed to the more permanent and improved performance & longevity from all-steel buildings.

We offer great long term & flexible rentals but you are always welcome to purchase, outright or spreading the payments via Lease so you own it after you’ve paid for it. You can rent first then opt to buy later and we’ll offset some of what you've already paid from the purchase price - this is not the industry standard so we recommend comparing the others' Terms before rushing in!

Lastly it’s useful to mention what they are not… you’ll see from the pictures these are not flimsy bolt-ons, so we can’t use shipping containers as walls or anchorage.

Tunnels to connect, or truly temporary cover, even as a Planning workaround...

When you need quick, easy, movable cover...

There's a wide range of useful applications these retractable tunnels satisfy, some obvious, others less so.  There's covered transit (vehicles, forklifts & people; cover between buildings at work, transport terminals, hospitals and wet weather queue cover...) and there's temporary cover; anything from vehicles to machinery and truck loading areas. A main advantage is there's a covered area only when it's needed and then retracted again when not - ideal for sites where spare space is not abundant, i.e. almost everywhere in southern UK!

The tunnels work either on rails (so strong & fixed to a certain track/route) or on wheels allowing them to be moved between locations. Either way, they are easily retracted and deployed according to needs. They are robust and yet lightweight with aluminium frames and covered in PVC but with various options (windows, doors, around corners and down hills etc), translucent, different colours, branded... The tunnels have a pantograph, concertina system that affords significant versatility.

And whilst we always advocate compliance with standards & rules, prospective customers are sometimes keen to avoid going through the Planning process (yep, most 'temporary buildings' need Planning, just like a building) but if you have a retractable tunnel that's on wheels, well, it's pushed back and away when not in use, so in use for less than 28 days at a time...

We'd love to hear your comments & questions or If you have a potential needs that could be solved using such a tunnel... please just get in touch with us using the contact enquiry form.

PVC Roofed BigBox Temporary Building


A temporary building has a PVC roof to keep the structure lightweight, even with steel walls, glazed windows, roller doors, fixed or retractable building links etc. They are engineered to last for many years in situ, can be extended as needed and parts can be replaced individually if worn or damaged. Quite simply a really useful tool for so many businesses!

Aluminium Frames

Aluminium framed building.

The most well known, most tolerant of poor surfaces, quickest to install and cheapest to move - often making them the best choice, or even only choice if a decision is left to the last minute. If you search for "temporary buildings" most companies ONLY offer these aluminium systems - whilst they are suited to many applications, they have their limitations (single span/width size, height, strength, security, PVC gables, internal cables, noisy in the wind...), so there are plenty of situations you should consider steel frames instead.

Steel Frames

Steel framed buildings with a PVC Roofs.

Steel framed "temporary buildings" - are much stronger and usually cheaper on a like-for-like basis (size/spec against aluminium), or allow considerably wider (treble the maximum sizes allowed by aluminium!) and much taller structures, although they have a longer lead time. With a PVC roof they are still 'lightweight' or 'temporary', work on most lower quality hard surfaces (not usually requiring ground-works, like aluminium) and have other benefits such as use of the whole roof space and being quieter in strong winds. So in many cases, steel is the better choice and yet rarely considered!


A PVC roof can be double-lined (or inflated) for anti condensation and provide basic insulation, so usually most suited to ambient storage - but it isn’t always the most suitable or desirable e.g. due to poor security and they will wear out every 10-15 years, which is why we also offer a permanent all-steel solution, including the roof, for long term use and proper insulation & higher standards.


We’ve completed projects with non-standard shapes & bespoke specifications in steel, so we aren’t confined to rectangles or restrictive standards: if you really need a triangle, pentagon or rhombus we can do that!


A 60m single span x 200m x 16m eaves height "temporary" building (for bulk storage or other huge open space needs) can be available for use at a windy quay side for example, even on a tarmac surface, considerably quicker and cheaper than putting up a traditional store.


Remember when creating an indoor facility on a previously outdoor surface, that surface won’t perform like your warehouse with its purpose-designed indoor floor. Whilst not mandatory for anchorage/stability, it will usually function much better with some preparatory groundworks, e.g. perimeter drains, slope correction near doors, slightly raised pad or ring-beam to manage rainwater and provide better/easier anchorage, all of which we can help you with.


A temporary building is produced and installed relatively quickly; often just 6 weeks’ lead time (larger and steel frame structures take longer). Although the installation might seem like a construction process, these structures go up quickly, often within the week. In our quotes we include all plant and construction equipment necessary for the build, so you get an 'all in' price. Standards of finish, fitting and performance are discussed long in advance so customers have a clear understanding to avoid unpleasant surprises - we believe in full honesty!

The main benefit: cost and speed

Many customers choose temporary buildings because they are a great quick and cost effective solution. As well as providing quick onsite facilities, they usually require no ground-works; just an existing hard standing to prevent subsidence. But we also help folk understand the weaknesses - and to consider alternatives.
