Design and build specialism
in a range of sectors

Our industry expertise means we deliver excellent value across various sectors, bringing a level of flexibility to every project that can only be achieved through experience. Working with us is a simple, transparent and collaborative process and final results go above and beyond expectations.

Explore what we do, and how we do it:

Commercial office fit outs

We deliver commercial office services spanning shell and core, category A and category B fit outs. We have many years of experience in this sector, covering everything from fit outs for new builds, to category B projects involving occupied buildings.


We have many years’ experience providing full turnkey design and build solutions to various clients in the retail sector. Some of our recent projects have involved food and clothing retailers, as well as high street banks.

Critical facilities

S-WORX covers critical facilities in new builds and occupied properties. We have a wealth of experience in this sector, providing solutions for comms rooms, server rooms and data rooms, as well as completing resilience upgrades.

Plant replacement

We can replace and upgrade MEP plant including boilers, switchgear and generators. Works are often required in restrictive environments where our expertise is called on to minimise downtime and avoid disruption for the client.

Where required, we can carry out detailed, in-depth validations and surveys to establish the status of existing services in a building. We can then discuss the best solution and how it can be tailored to you.

Our commitment to you

We offer design and build excellence. From the moment we take on your project, we are committed to achieving industry-leading quality and providing an unrivalled client experience.

We adopt a flexible, supportive approach, acting with honesty and integrity. We see our commitments through and find the best ways to support our clients.

We offer unrivalled design capabilities, bringing projects to life and saving time and money using building information modelling (BIM) and computer aided design (CAD).

Award-winning constructors

Detailed resource is committed from day one. By the time we arrive on site, we will have established all requirements – design and procurement will be fully reflective of this.

Projects are closely monitored from tender to completion. We use comprehensive management systems and issue weekly reports so you have full visibility of progress and costs.

Our team brings a positive, can-do attitude to every project. We’re proactive and responsive, remaining flexible to change where needed and striving to achieve the very best, first time.

Our management systems and processes are those of a large, well-established company. At the same time, we are still able to provide the flexibility and responsiveness of an independent business. There is nothing our clients can’t see: we operate with complete transparency and if you ever need us, we’ll be here.
