We know that offices are rarely just places to house people - we make sure your office is as resilient and agile as your business.

Businesses in the midst of change require specialist teams that understand the related pressures and complexities. At ISG, we know the office is rarely just a place to house people and systems; it is a key part of your business infrastructure. It forms the backbone for sophisticated technology and operations. It plays a key role in attracting and retaining the best people. As such, it must be as resilient and agile as the business that occupies it.

Business Development Director, UK Fit Out

ISG has a strong legacy of creating offices that touch every aspect of the modern workplace. From new corporate headquarters, refurbished technology-led offices to the smaller moves and changes that keep companies competitive, we take our roles as enablers of business very seriously. We ask tough questions, challenge conventional methods and ultimately deliver offices that are more resilient to the future than their counterparts. We care deeply about helping our customers meet their business goals—and our extensive track record, exceptional client list and rate of repeat business prove it. 

We have specialist teams for each stage of the office lifecycle and for all budgets. We build, refurbish and fit out for developers, landlords, owner-occupiers and tenants in London, across the UK and in each of our global hubs in Europe, the Middle East and Asia. 

We are the number one fit out company for offices in central London but we are an office specialist across the world. We have a vast pedigree of projects for global blue chip clients, public sector organisations, media companies and smaller start-ups. We focus on your business drivers. Our experienced teams support landlords in transforming new and existing building stock into state-of-the-art prime space that attracts the best tenants. We recognise the ever-evolving needs of today’s occupiers, and we help our customers achieve impressive occupancy rates.

Our sustainability team is always on hand to make recommendations on how to improve EPC ratings and achieving BREEAM certification to future-proof stock, improve running costs and increase return on investment. 

Strength to strength. Shoulder to shoulder. End to end.

We are proud of our heritage in the commercial offices sector. This brochure is an overview of our global capability working across our four service lines of fit out, technology, construction and development.
