Testimonials

  • "LaSalle are really happy with the fitout on Castlereagh St. Sheldon have done a really great job providing lots of variety of workspaces and a striking design."

    Gareth Sneade, Senior Vice President, Asset Manager, LaSalle Investment Management

  • When the quality of suites is this good [as Sheldon] why wouldn't occupiers outsource this to owners, rather than going through all the challenges of building it themselves?

  • Speculative suite design refers to the process of designing and constructing office spaces without a specific tenant in mind. These designs aim to appeal to a broad range of potential tenants, balancing modern aesthetics with functional versatility.

  • Speculative suite design can attract a wider range of potential tenants by offering ready-to-move-in spaces that minimise the need for extensive customisation. This approach can reduce vacancy times and appeal to tenants looking for quick and easy office solutions.

  • Key elements include flexible and future focused layouts, modern and neutral aesthetics, high-quality finishes, energy-efficient features, and a wide range of work points. These elements should cater to general market trends and aspirational tenant needs.

  • Balancing cost and quality involves selecting materials and finishes that offer durability and appeal without excessively driving up costs. It's also important to work with contractors who can offer a turn-key solution, with a robust planning process that prioritises material reuse to reduce environmental and financial costs.

  • Effective marketing involves showcasing the suite’s ready-to-use condition, flexibility, and modern features. Virtual tours, high-quality photography, and highlighting unique selling points are crucial in attracting tenant interest. At the end of the day, the quality, location and functionality of the suite will be its greatest draw.

  • In 2023-24, tenants that have leased Sheldon’s spec suites largely consist of financial, professional, and technological services companies. The adaptability, size, and requirements of companies in service industries make them viable for the generic yet aesthetically sophisticated appeal of spec suites.

  • 97% of Australian companies now offer some kind of hybrid working arrangements to employees. Knowledge around a company’s office capacity and density due to hybrid/remote working arrangements is key in delivering suitable workplaces for them. High quality technology and meeting rooms is essential for hybrid working.

  • Spec suites can offer sustainable solutions through the reuse of existing materials in the design, reusing base building elements such as flooring and ceiling tiles, and diverting or donating unused materials.

  • To create truly future proof spec suites that will serve as strong assets to a building for a long period of time, they should be designed with multiple tenancies in mind. Providing modular and adaptable options is the best way to make the suites last well into the future.
