Flex | 99 Walker

Consider this your workspace, enhanced through quality ‘pay as you need it’ shared services and your name on the directory board. Here we celebrate true workplace flexibility, as SME’s can access a network of high-quality offices without committing to long term leases, rental bonds or expensive fit outs, and large corporate users in the building have the option and efficiency of project, meeting and short-term space.

Key Features:

  • Your business name on display, promoting your brand and individuality.
  • Modern office fit-out, reflecting your professionalism.
  • Contract direct with Abacus, the landlord, on flexible terms that work for you.
  • Seamless booking and billing technology.
  • Access to Abacus’ national portfolio, to assist your business placement and growth.

Previously, the traditional flex offering was only available in branded co-working and serviced office operations. Tenants were treated as ‘clients’ and were required to operate their business under the branding of the operator, an approach that we believe is unfair to SME’s and simply does not work for large corporate users.

Technology, the proliferation of co-working brands and a global pandemic have challenged how businesses operate within the office, resulting in an increased need for more diverse and readily available choices from landlords.

Our team are leading the way in this evolution. Branded by your business, and used how you want, Flex by Abacus is the answer to truly flexible work arrangements, combining the best elements of serviced office/co-working and traditional office leasing.

Building Management

The Building Management Team care for all aspects of the building, from maintenance to operations, ergonomics and sustainability. They handle administrative tasks, promote our tenants and ensure safe and enjoyable spaces for collaboration and renewal. They form an integral part of our strong partnership with our tenants, and understand that without this, the building wouldn’t be able to thrive.
