In short, you will see the basic internal framework of the building as presented by the developer. While the main office space(s) will be in a “bare bones” state, developers often finish the communal areas to a high standard. These may include lifts, toilets and the reception; i.e. the areas that all the building’s occupiers can use. What is a CAT A Fit Out?

This generally includes work to the flooring, ceiling, fire and safety facilities, mechanical and electrical services, air-con and ventilation, basic internal finishes and more depending on the space. Following CAT A work, the space is essentially takes the form of an empty, open plan “blank canvas”. There are no desks and chairs, decorations or meeting rooms, as these elements are left to the incoming tenant for the next phase of the fit out – the CAT B. What is a CAT B Fit Out?

Tenants oversee and fund this part of the work, as they need to tailor the space to suit their unique needs and working practices. In addition to making the space suitable for the incoming workforce, tenants will play a big part in developing the aesthetic so it reflects their company identity and branding. Usually, the tenant will consult the help of an office fit out company to develop the space design and, later, conduct the install of the new elements. These may include, but are not limited to, the following: Office furniture solutions – Common furniture solutions include shared and individual desks, task chairs, height adjustable desks, soft furnishings, meeting tables, pods and booths. Meeting rooms – Partitioning will be required to create private meeting rooms. These are essential for collaboration, Zoom chats and meetings where employees share sensitive information. Decorations and Branding – These are key in making the space look inviting and creating a brand experience. Many companies introduce bespoke glass manifestation, feature walls and decorative acoustic panels. Other elements covered by CAT B include breakout areas, finishes, kitchen areas, ICT solutions and power points. Once the tenant is happy with the makeup of the space, the office is ready to move into. Related Content: Office Design Trends and Ideas 2022 How About CAT A+? The CAT A to CAT B model typically requires tenants to sign a fixed, long-term contract. However, in the current market, many tenants are seeking shorter-term contracts that offer more flexibility. This has resulted in landlords offering an alternative to the CAT A to CAT B model, known as CAT A+. The CAT A+ model is simply where landlords offer pre-fitted, fully furnished spaces to tenants on a shorter term deal. The spaces are connected to Wi-Fi, allowing tenants to easily plug in their devices and work away. This is why many people refer to these spaces as “plug and play” offices. Simply put, tenants get a fully functional workspace without having to commit for the long term, which is particularly attractive to small, ambitious businesses.
