On-Brief Office Fit Outs for Landlords and Tenants

With 30+ years’ experience transforming interiors across London and the UK, we understand the importance of a quality office fit out. For landlords, it’s essential the space is fitted out to a high standard to attract tenants and reduce vacancy rates. For tenants, a well-executed fit out is key in creating a high-performance space where employees thrive.

If you are a landlord, we offer a range of CAT A office fit out services to create a functional and compliant “blank canvas” to put to market. From the ceiling installation to electrical work to laying new flooring, we’ll get the property in order so you can start leasing asap. We also offer a CAT A+ fit out service so you can offer a ready-to-use space if you wish.

If you’re an incoming tenant, we will bring our design flair to the CAT B fit out project to create a tailored office space. With an experienced in-house design team, we can guide you on office furniture, branding, decorations, layout solutions, and more.

Our Office Fit Out Process

Our time-tested project process has ensured countless clients have received outstanding office fit outs. Over the years, we’ve helped everyone from London tech firms to high-achieving corporates and innovative creative agencies.

Here’s an overview of how we work:

  • Site Survey

  • Project Proposal

  • Transformation

  • Client Aftercare

We kick things off with a site visit to evaluate your space and discuss the project objectives in more detail. During the visit, your designated surveyor will take measurements, identify potential challenges, and firm up the brief to feed back to our design and project teams.

The survey also allows us to get to know you and build a rapport, which is an important part of the transformation process.

If you’re a tenant, we’ll devise a stunning office design scheme in accordance with the survey information and brief. Our designers will provide a creative, original concept and work closely with you to tweak it to your liking. Depending on your preference, they can create a comprehensive 2D floorplan design or a lifelike 3D render.

For landlords, we will create a detailed proposal for the CAT A fit out works. This typically includes a layout of key elements, such as electrical items, plumbing, and HVAC systems.

Next, our project team and skilled tradespeople will conduct the fit out with renowned speed, efficiency, and professionalism. Having managed fit out projects for 30+ years, you can count on us to deliver a successful transformation.

To do so, we devise a schedule of works that provides a clear project roadmap. We understand that delays can be very disruptive to businesses, so this helps us to stay on course to meet the agreed timescale.

This typically includes the installation of lifts, washrooms, receptions, entrances, loading bays, and stairs. We will oversee this process to ensure your office is safe, functional, and durable.

CAT B Fit Out

For incoming tenants, we can complete the CAT B office fit out in accordance with your unique requirements. From the decorative elements to furniture installation and the creation of work zones, we will build a space that supports the way you work and reflects your brand identity.

CAT A + Fit Out

For landlords looking to offer a “move-in-ready” environment, we provide a premium CAT A+ service.

Tenants may be required to fund restoration works at the landlord’s request. These works are called dilapidations, and landlords can schedule them during or at the end of a tenant’s lease. We have vast experience in delivering fast and seamless dilapidations, helping you to move on to pastures without stress and complications.

“Rap Interiors definitely lived up to our expectations. What attracted us to Rap was the fact that they could handle the design, construction, and furniture elements of the fit out. This meant that although there were a lot of decisions that had to be funnelled through them, we didn’t have to work with multiple companies.”

Ruth Simpson, Simpsons Wine Estate


What’s the difference between a CAT A and CAT B fit out?

CAT A fit out works are the basic finishing of the building’s interior. They are commissioned by the landlord in order to create a “blank canvas” ready to put to market to find a tenant. At this stage, the space does not include things like furniture, decorations, or partitions that create work zones.

Once the landlord finds a tenant, the CAT B fit out phase begins. Tenants conduct this part of the work, as they need to tailor the space to suit their unique needs and working practices. Typically, the tenant will work with an office fit out company that will design and install elements like partitions, furniture solutions, branding elements, and breakout spaces.

How much does an office fit out cost?
