Construction services

When it comes to construction, our vision is our customer's vision. We drive dynamic solutions to reach exceptional results.

When it comes to construction, our vision is our customer's vision. We drive dynamic solutions to reach exceptional results and make a difference to the people and communities that we serve. We have a strong track record of construction and engineering projects throughout the UK and Europe from single-storey construction to large-scale schemes including commercial offices, educational campuses, hotels, leisure centres, student living, shopping outlets and datacentres.

With our roots in fit out, it is not surprising that ISG is trusted with some of the most complex refurbishments, restorations and retrofits as well as traditional new build construction projects. We thrive on tight programmes and logistical complexities. We understand that delivering projects is not just about square footage or scale; it’s about being trusted with the responsibility to make an idea come to life, working back from the needs of the end user, and building lasting client relationships.   

New build

Working across private and public sectors, we offer new build capability across all sectors, creating places for people and businesses to thrive. From an office to a school to a distribution centre, whether the key driver is meeting a challenging programme or achieving maximum community impact, we will work with you to deliver your vision.

We also have specialist teams borne out of these strong client relationships, creating an offer that truly meets their needs, and in turn benefits the sector, driving the innovation to improve efficiency and deliver revolutionary change. From an engineering services team that delivers hyperscale datacentre solutions, providing a responsive solution that brings resilient capacity online quicker, to the development of a logistics and distribution division that recognises that speed and ease of fulfillment is critical to our retail clients’ success.

Refurbishment and restoration

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 tenant needs. With extensive experience working with conservation bodies and funding organisations, we are also proud to have been trusted to restore many prestigious and listed builds that boast rich histories, including the largest greenhouse in the world with the five-year restoration of The Temperate House, Kew Gardens, London, UK.
