Unusually, they have names: Vanderlande, the smaller of the two has a roof area of 38,170 m2; while Savoye is a colossal 66,116 m2.
Their story began back in November 2005, when architect RPS Burks Green was commissioned for their design.
Principal architect, Kester Purslow, explains the initial work: "The process of designing the buildings started with assessing the client's requirements and making sure that the solution embodied the physical restraints of the work model, to create the most efficient solution.

In its striking IKEA colour scheme of grey and blue the building rises to seven stories and has a floor space covering the equivalent of eight football pitches.
The skin of the building was then designed around the work process in an aesthetic manner, which complimented and elevated the surrounding environment".
This sounds technical but essentially what the architect did was to take the employer's documented requirements and the client's wishes and work very hard to produce a scheme that not only satisfied the brief but also surpassed expectations.
High on this list of requirements was fire safety.
"An overriding factor in the design has been the fire strategy," says Purslow.
"The escape strategy for each building is quite complex, due to their size and the mechanical handling and storage requirements of the client.
Each building has large four hour internal firewalls to separate the fire risk at the request of the client's insurers.
"The cladding also had to include non-combustibility requirements.
We designed a built up system, rather than a composite cladding system, to meet their needs".
The architect specified Corus Colorcoat Prisma and Colorcoat HPS200 for the walls and roofs, respectively.
The systems used met the fire strategy and provided Purslow with the "quality, life expectancy, colours and guarantees" required for the project.
Cladding contractor YSIS first learned of Vanderlande and Savoye in February 2006, when it was approached to tender for the job and the firm started on site on 11th July 2006.
As with most of these contracts for large distribution unit time was of the essence.
"We provided a weather tight envelope to the on 30th October 2006, just 17 weeks after our start on site," says Verity.
The cladding contractor worked closely with both architect and steel fabricator to ensure that the project ran smoothly and that the detailed design benefited both it and the following trades.
On Vanderlande, YSIS installed 16,379m of Metallic Silver and Mountain Blue Colorcoat Prisma on the walls and 38,170m of Goosewing Grey Colorcoat HPS200 to the roof.
Savoye dwarfed its little sister: clad in matching colours, it required 22,086m of Colorcoat Prisma to the elevations and 66,116m of Colorcoat HPS200 on its roof.
"The sheer scale of the development and the coordination complexities of the internal fit out requirements, along with Next's requirements, meant a challenging coordination and communication exercise," says Purslow.
"In terms of timescale this wasn't an unusual project.
However, it was unusual to have two separate units of this size being built alongside each other at the same time." At the peak of the project YSIS had 80 operatives on site.
Labour had to be brought in from far and wide but to satisfy quality systems and ensure that a high standard of workmanship was maintained the contractor only used labour already known to it, or those who were able to demonstrate their ability and experience backed-up with references from contractors they had worked for previously.
The height of the buildings, at 24 m, necessitated the use of extremely large booms for the installation of the safety netting.
While to carry out the external cladding special mobile elevated working platforms had to be resourced.
"The original specification for the project did not call for Corus products," says Verity.
However, safety is paramount on all YSIS projects and due to the unique safety benefits afforded by the supplier of the cladding system - sequential packing and testing for non-fragility in place - together with the strength of Corus, there to backup the life of the product, 25 years for Colorcoat Prisma and 30years for Colorcoat HPS200, there never was any doubt as to what material should be used as far as Y.S.I.S.
was concerned.
"The specification that was agreed was a 25-year warranted TwinthermTM roof and sidewall system.
It provides our customers excellent value-for-money and allows peace of mind for all concerned.
And, having completed this project successfully we are confident that there is nothing too large for us to cope with and look forward to working on 'monster sheds' in the future." Case study.
