CAT A and CAT B commercial fit outs differ in purpose and level of completion: CAT A provides the essential structural elements, basic services and safety systems, while CAT B builds on this foundation by adding customised design, partitions, furniture, technology and finishes to create a fully functional, branded office environment.

DBSJ provides an integrated office interiors fit out solution – combining design, build and joinery. As custodians of your brand, we turn your vision into a reality.

Working with us as your new office fit out provider
Backed by extensive experience in the office fit out sector — and partnerships with leading UK and international traditional and flex office brands including Spaces, Regus and Signature — DBSJ brings frontline insight into an evolving marketplace and the trends reshaping demand for businesses, brands and landlords alike.
Driving that change are employees expecting better experiences, landlords needing revenue-generating spaces, and operators under pressure to create workplaces that feel more like hospitality venues than traditional offices. That’s where DBSJ comes in.
We design and build offices that attract people back in, increase occupancy and deliver a premium user experience. From CAT B fit outs and turnkey flex office schemes to bespoke joinery and amenity spaces, every project is delivered with one goal: exceptional results on day one and year 10.
When we deliver a centre with DBSJ, our opening occupancy numbers are exceptional. This is due to the quality of the centre and the fact they are always open on time. If there were delays, even by a week, it would impact our sales as we’d have to find alternative office space. However, we trust DBSJ to deliver on time.
Whether you’re repurposing underperforming space, developing a CAT A+ product, creating a premium flex hub or upgrading a traditional office, we help you:
- Increase opening day occupancy
- Create hospitality-led clubspaces for communities
- Improve tenant satisfaction and retention
- Make every square metre work harder
- Elevate brand perception and experience
Our work covers private offices, coworking floors, clubspaces, reception areas, libraries, kitchens, meeting suites, phone booths and more; all supported by in-house bespoke joinery to guarantee quality, durability and brand-led detailing.
Please contact our team about your office fit out requirements. We would love to answer any questions and establish where we can help.

Flex office operators: Flex office customers are looking for the right third space; the place between home and work where they can be productive, inspired and connect
They want places with atmosphere, comfort and character. At DBSJ, we help operators build hospitality-led workspaces that feel like a destination. Our experience spans new openings and brand rollouts, with rapid programmes, in-house joinery and a finished product that looks premium from the moment the doors open. Lounges, clubspaces, acoustic zones and amenity-rich areas are designed around community, productivity and visual appeal, giving operators a space that fills quickly and retains members. Whether you are upgrading an existing location or launching a new one, DBSJ provides one accountable partner from design through to delivery.
Private & corporate office occupiers: CAT B office fit outs are not just about adding meeting rooms, kitchens and desks
They are about creating a workplace that feels like a destination with purpose. At DBSJ, we turn empty floors into branded, functional, experience-led environments that people genuinely want to work in. Our CAT B schemes balance aesthetics, practicality and user experience, with seamless coordination from design through to delivery and in-house bespoke joinery for quality you can see and feel. Every detail is considered: acoustic comfort, intuitive layouts, brand expression, technology integration and hospitality-style amenities that support productivity and wellbeing. With one accountable partner, clients benefit from faster programmes, fewer interfaces, reliable cost control and a space that is ready to occupy on day one. If you need an office that performs commercially and feels like a place where people belong, DBSJ delivers CAT B spaces that work and work hard.
Office landlords & asset managers: Empty floors and slow leasing cycles are expensive. DBSJ helps landlords turn unused spaces into ready-to-occupy workplaces that attract tenants and generate revenue
We deliver CAT A+, plug-and-play offices and flexible amenity spaces that meet the expectations of hybrid workers and modern occupiers. With in-house design, cost planning, joinery and fit out, you gain a single accountable partner and faster speed-to-market. The result is a finished space that photographs well, shows well and performs commercially. If you need a reliable fit out partner to lift occupancy and unlock revenue from underused space, DBSJ delivers spaces that are built to be leased.

Frequently asked questions
Fit out costs vary depending on size, specification, building condition and the level of finish you want. Once we’ve understood your brief, reviewed design options and visited the site, we can provide a budget cost so you can plan confidently and avoid surprises later.
An office fit out typically takes 6-12 weeks for spaces up to 20,000 sqft but this depends on the scope of works and complexity of the building. Thanks to our in-house capabilities, we are able to offer fast turnarounds and a very clear programme from day one.
We provide a start-to-finish service, including workspace design, furniture supply and technology integration, not just construction. Our team manages everything from concept and space planning to sourcing and installing high-quality joinery and tech.
