Knowing buildings... inside out.

Transforming Spaces for over 70 Years.

Collins is one of London and the South East’s leading fit out specialists – and one of the few with the expertise to deliver complex structural adaptations alongside high-quality fit out.

For over 70 years, we’ve shaped the commercial office and reimagined spaces across sectors, delivering projects from £1m to £75m with the same focus: clear communication, precise delivery, and outstanding quality. Every project is treated as our best, creating a journey for clients that is collaborative, rewarding, and results in an asset built to last.

Discover Who We Are

Collins Approach Refurbishment to Finishes

We integrate structure and fit out into a single streamlined process – saving time, reducing risk and ensuring quality at every stage. It is complex fit out delivery…made simple.
Cat A / Cat A+ Fit Out

At Collins, fit out is the craft of making spaces work. From high-quality interiors to smart structural adaptations, we tailor every project to the building and the people who use it.
Cat B Fit Out

We believe quality is defined by what sits behind the finish so our focus goes beyond surface-level design; we consider materiality, detailing and performance from the outset.
Refurbishment

We lead with reuse and rethinking established spaces. From listed buildings to commercial upgrades, our strength lies in preserving what works and improving what doesn’t.

“It was an enjoyable and collaborative journey working with Collins to create Landsec’s first ever flexible co-working space, Myo. Working together was a pleasure from start to finish, both in terms of the team and the end product. The team’s excellent communication and flexibility helped ensure any issues were easily & swiftly resolved. I would recommend Collins for future projects.”
