Overcome the challenges of modern sustainable construction
We know that architects, builders and facilities managers need to meet regulatory requirements for energy-efficient, low-carbon, high-performance structures, while at the same time delivering practical, aesthetically pleasing and cost-effective buildings for end users.
The Ultima Building System from Portakabin Limited helps you achieve all of these objectives. Our Ultima building modules are fabricated off-site under strictly controlled factory conditions, where accurate, high-specification construction can be achieved. It’s an intrinsically sustainable form of construction, generating very little waste and minimising disruption on site.
Outstanding thermal efficiency for a comfortable, cost-saving, energy-efficient building – all year round
The Ultima Building System itself comprises high-quality, robust all-steel modules that deliver market-leading levels of thermal efficiency, with excellent insulation to keep the heat in and the draughts out. What’s more, tests conducted by the Building Research Establishment (BRE) show that our buildings exceed the Building Regulations Part L air-permeability requirements by 70%. That means you can achieve a low-carbon building that delivers energy savings and cost savings for life.
There are no limits on your design ambitions with our flexible building system
Ultima modular buildings offer incredible versatility. Our skilled designers will work with you to create a building of any size, up to 24 storeys high, to meet the particular demands of your application and site. You can have acres of column-free office space or intricate networks of rooms and corridors, or a combination of both, to suit your needs. Our buildings create comfortable, spacious and bright workplaces, whether you need to accommodate a small number of people – or more than 1,000.
Flexibility extends to the look of your building too, so there’ll be no restrictions on your creativity. With our range of design options, your building will look just the way you want it, whether you choose timber cladding, brickwork, a pitched roof, external canopies, a dazzling paint job or any other architectural embellishment.
