With our roots in fit out, it is not surprising that ISG is trusted with some of the most complex refurbishments, restorations and retrofit projects as well as traditional new build construction projects. We thrive on tight programmes and logistical complexities. We understand that delivering large projects is not just about square footage or scale; it’s also about being entrusted with a big responsibility to make big ideas come to life.


When it comes to refurbishing or retrofitting, ISG is one of the most respected and active specialist contractors. We have delivered numerous complex refurbishments, often in occupied buildings. We have a strong track record in transforming tired and unproductive real estate into vibrant and inviting spaces, always meeting both the developer and tenants’ needs. 


With extensive experience working with conservation bodies and funding organisations, we are proud to have been trusted to restore many prestigious and listed builds that boast a rich histories. From straightforward to complex structural alterations, our expertise within listed and heritage environments means that we are able to craft intelligent and dynamic solutions to meet the needs of each individual client.


We understand that a sustainable approach to development, retrofitting and reusing as much of the fabric of the original building wherever possible, is good for both our customer’s bottom line and the environment.  We have an enviable track record in bringing older stock up to the latest environmental standards, and have delivered numerous BREEAM ‘excellent’-rated refurbishments.


Sometimes buildings just need a refresh instead of a rebuild. Our team of experts can take rundown buildings with complex external refurbishments, and transform them into modern, vibrant and smart spaces. This has allowed our customers to bring new life to old buildings, and in effect, a brand new building back to the market. Reenergising façades can not only completely transform a building’s fortunes, it can also significantly improve energy efficiency and whole-life costs.


ISG has its own joinery workshop in the South of England to provide our clients with high-quality, custom made products. Our craftsmen produce bespoke, high-quality cabinets, tables, lighting and mirrors for projects across the globe.

Exhibition Centre Liverpool

We were appointed by Liverpool City Council to deliver the £65 million Exhibition Centre Liverpool and Pullman Hotel development on the city’s waterfront. Constructed concurrently, the exhibition centre hosted its first event in September 2015 and the hotel opened to the public in February 2016.

Agilis Schools

ISG and Stride Treglown have developed a model school template with a compact and efficient floor plan achieving a 5% reduction over Building Bulletin 99 guideline areas in line with the EFA requirements. The template has already been rolled out successfully across a number of schools and is proven to deliver modern, dynamic and affordable education spaces. Unlike other solutions in the marketplace, we recognise that every school is different and flexibility underpins our design.
