Agile retail construction solutions

Retail is a fast-paced industry that thrives on its ability to respond quickly and meaningfully to its customers. At ISG, we set out to do the same for our customers. Across our business, we nurture an energetic and agile culture that rewards great ideas, fosters mutual trust and encourages care for our customers and communities. As a result, we are capable of not only delivering what you need when you need it, but also doing so with a genuine desire to deliver it better than expected.

For our customers, no problem or project is too small, and no request too great. The depth of our capability and supply chain has expanded in large part in response to the needs of our customers for a range of services and skills. Our goal is not just to deliver projects but also to align ourselves with your current and future needs. We measure our success in terms of our ability to respond quickly and solve your problems effectively.

Nurturing long-lasting relationships

25 years of service and counting: Our first project for the supermarket chain, Asda (a subsidiary of American retailers Walmart), was in 1993. We have since delivered hundreds of projects with Asda covering a range of construction services. When Asda acquired the Netto chain of supermarkets, we were required to rapidly convert 67 stores, with eight projects under construction at one time. Through maximising efficiencies and value engineering, we saved the store £28m. Our work with Asda has seen us cultivate closer ties to some of the UK’s other leading supermarket chains, including Morrisons, Lidl, Waitrose and Marks & Spencer.

Protecting your global brand

Best foot forward: Our work at the flagship Size? shoe store in Milan was borne out of our long-standing framework relationship with JD Sports, which owns the Size? brand. Our European team had four weeks to turn a former retail space into the style and messaging for the Size? brand. No matter where our clients are located, they can rely on our global ISG retail teams to deliver a consistent brand message which transcends layouts, buildings and geographies.

Overcoming logistical challenges

Our journey with John Lewis: Problem-solving is part of the job for all of our construction teams. When faced with delivering the largest John Lewis store outside London – located in the heart of Birmingham city centre and above New Street station – the need to plan strategically and effectively became paramount, especially when faced with a fixed, non-negotiable deadline. This flagship retail project for ISG was met with restricted vehicle access, limited storage capabilities and exceptionally busy public areas. We created a complex delivery programme to meet the project requirements and transform the building’s empty shell into a high-tech retail environment in only 33 weeks.

Updating listed buildings while Paris Sleeps

British fashion in a Parisian setting: We have a proven track record in delivering exquisite, stylish retail environments in listed buildings. Our Paul Smith store on the iconic Rue de Grenelle in Paris involved fitting out two levels in a protected building, installing new mechanical and electrical facilities as well as a bespoke terrazzo flooring – the first for any Paul Smith store anywhere in the world. With the building fully occupied and with a school located nearby, the majority of the works were carried out after 8pm. Despite the challenges, the project team delivered the job in only seven weeks – just in time for the Christmas shopping season.

Supporting your business expansion

Experience movie-star glamour at Charlotte Tilbury: We were privileged to work with the internationally renowned make-up artist Charlotte Tilbury on her second stand-alone UK store, located in Westfield’s White City shopping centre in London. Given the very personal nature of the Charlotte Tilbury brand, we worked closely with the client to manage all design changes, and ensure a smooth delivery in a very busy retail environment. We utilised our highly capable mechanical and electrical teams to install vibrant lighting and technology throughout the site, such as illuminated light-boxes and digital screens. The resulting store is visually striking, and an illuminating testament to the smart, agile, customer-first nature of our retail teams.
