Fit out - Major projects

Creating clarity, order and efficiency from large-scale, challenging works is what drives us.

An inspired fit out gives a newly built or refurbished building a whole new personality. It gives occupiers the chance to put their own indelible stamp on the space and create a truly bespoke interior that speaks loudly about their organisation as well as stimulating productivity and enthusing staff, clients and visitors.

Delivering major fit out projects is all about navigating complexity. At ISG, creating clarity, order and efficiency from large-scale, challenging works is what drives us—and with some of the largest office fit outs in London on our books, we have the portfolio, accolades and repeat business to prove it.

Problem-solving culture

With our major project experience has comes perspective. There are few issues we haven’t tackled, few lessons we haven’t learned, and few tough conversations we haven’t had. We understand what it’s like to stand in our customers’ shoes, and we work diligently to meet their needs and address their concerns long before they become problems. To do this, we nurture a culture that asks questions and challenges the status quo. In simple terms, we work harder to deliver better.

Truly the best people

Every company claims it has the best people, but we know it for certain. Quite simply, the industry’s people most skilled and experienced in delivering major projects work at ISG. They have grappled with scale; they have navigated complexity; and they have delivered with pride again and again. We know how fortunate we are to have them—that’s why we work diligently to create a culture that is exciting and challenging, supportive of their ideas, and rewarding of their excellence.
