Plug-and-play floors that lease in weeks, not months.
The market has changed. Tenants want turnkey spaces that are ready from day one, and landlords want floors that let quickly and perform well. Our Cat A and Cat A+ fit-outs help landlords and asset managers reduce voids, support stronger rents and make buildings work harder from the outset. We call it Primed.
Fast-track, tenant-ready workspaces
We have achieved record results in terms of occupancy and signups… That is a testament to the quality of the finish and the quality of the product.

What is a Primed fit-out?
Exceeding tenants’ expectations with a CAT A+ fit-out.
Primed is our fast, flexible Cat A+ fit-out service for landlords. It transforms a standard Cat A floor into a finished, move-in-ready space, without tying tenants to a specific brand.
Delivered in as little as 6 weeks, Primed sits neatly between bare space and a full tenant fit-out. Each scheme is tailored to the building and leasing strategy, helping reduce voids, speed up lettings and make spaces easier to say yes to.
What is a Primed fit-out?
Less friction. Faster income. Stronger assets.
Measured by asset performance.
Primed is designed around the things that matter to landlords and asset managers – speed, income and long-term value.
Void days saved
When a floor is ready to tour and sign, marketing typically starts 30–90 days earlier than a traditional Cat A approach.
ERV supported
A considered amenity mix and proven performance help underpin stronger rental levels.
Faster absorption
Clear, finished space means fewer viewings, quicker heads of terms and, in the right market, pre-lets.
Capex efficiency
Optioned finishes keep costs within tolerance while maintaining a high-quality look and feel.
Clear ESG outcomes
EPC routes are agreed early, BREEAM pathways documented and embodied-carbon decisions captured from the outset.
Proven in practice
- Primed projects typically complete around 40% faster than traditional routes.
- FOUNDRY Wandsworth: 72% occupancy within six months of practical completion.
- Runway East, Brough High Street: 53% let on opening day.
- CEG Crescent: 23% was let at PC, rising to around 40% within three months.

Why Cat A+ outperforms Cat A
Cat A+ removes friction from the letting process. Instead of asking occupiers to imagine the finished space, it presents a workplace that’s ready to use. Decisions are simpler, timelines are shorter, and viewings convert more easily.
For landlords, the impact is practical and measurable: earlier income, reduced voids, clearer ERV evidence and stronger marketing from day one. With fewer moving parts for tenants to manage, Cat A+ makes it easier to say yes and quicker to get on with work.

Primed: CAT A+ Fit Out FAQs
What’s meant by a plug and play fit-out?
A “plug and play” style fit-out is often undertaken by a landlord to create a space immediately ready for a tenant to take over. Being able to offer a pre-fitted workspace to potential tenants speeds up tenant acquisition, reduces rent voids and provides landlords with a convenient and reliable competitive advantage in a rapidly-changing market. Interaction’s Primed service offers just this, with an experienced team creating fast-turnaround, high-quality spaces ready for tenants to call home.
What is Primed?
Primed is our “plug and play” programme – designed with the needs of landlords, serviced office providers and co-working operators in mind. Primed delivers high-quality, fast-turnaround workspaces that attract best-in-class tenants and “just work” from the minute they get the keys. Our experienced team provide a turnkey solution from the design through fit-out, including technology integration, furniture and interior styling. Explore Primed here, or take a look at some case studies.
How can a Primed space help a landlord?
Primed has multiple benefits for landlords looking to offer potential tenants a pre-fitted workspace. These include faster tenant acquisition, reduced rent voids and higher rental income. Read about Primed in our guide to Plug and Play offices.
How does a CAT A+ fit-out differ from a CAT A or CAT B fit-out?
CAT A fit-outs are a blank canvas for tenants who want a space that’s finished but ready for bespoke interior design and furnishings. CAT B fit-outs take this a step further with custom design features to infuse some originality and brand identity. In comparison, a CAT A+ fit-out has everything a tenant needs to get started right away – not just furniture and storage but technology, interior styling and any other finishing touches you’d expect in a fully-fledged office space.
Who is best suited for a CAT A+ fit-out?
CAT A+ fit-outs are not only great for landlords seeking ‘tenant-ready’ spaces where occupants can move in as quickly as possible. Some tenants want office space that’s conducive to strong and unique branding, to the extent that a shared co-working space may not be their ideal choice! A CAT A+ fit-out will not only have all the facilities that tenants need readily available, but it will also have the interior design and styling that makes an office space feel personal and unique.
How long does an office fit-out usually take?
We pride ourselves on Perfection at Pace, delivering on time, on budget and beyond expectations. Take a look over the case studies for Xledger, G2 Recruitment, Development Initiatives and Granger Reis, who were all on site for just 6 weeks before moving to their destination offices.
How do you quote clients for an office fit-out?
We help our clients from the very initial stages, using industry and market rates to assist with budgeting and choosing a building. We can then develop the process, taking a detailed brief including a targeted budget & specification. At this stage we would also design the project and cost the design, which becomes more accurate with every conversation between ourselves and the client. Naturally, we always work to a budget, but can also provide value engineering and upgrades as the project evolves.
How can I determine the return on investment in an office fit-out?
It’s not a one size fits all, as it depends on what you are trying to achieve from your fit-out. For example, some businesses may want to bring people back to the office while others are improving mental wellbeing, or company culture. Progressive companies are expanding the ways in which they track organisational health, looking at data points including NPS scores, project turnaround times, sick days and advocacy across social platforms.These are hard metrics but soft metrics will be equally, if not more illuminating. Regular agenda-free one-to-ones, exit interviews, off the record chats and open discussion forums will provide insight into what’s going on under the surface of your organisation – and how much further you may have to go. These factors collectively determine the return on investment of your fit-out.
