Creating the Vision

It all starts with the vision for your workspace. You’ll meet our friendly and experienced team of office designers, and we’ll work together to create a clear outline brief for your office interior project.


Workplace Research

Our approach to office design is more than just providing a creative space. It’s about improving the way your company works. We’ll explore the factors that link certain employee behaviours to better results, helping us design an office space that nurtures wellbeing and boosts productivity.


Block Planning

Incorporating your available space into your office design plan, our workplace and office interior designers will construct block plans outlining how you could allocate your space to get the best from your resources.


Office Concept Design

Our office designers produce initial concept sketches of your workplace design, giving you complete control and collaboration with our office interior experts to craft and revise your design accurately. Once you’re happy with the concept drawings, we begin creating a 3D visualisation of your office space design.


Office Detail Design

Our office designers produce a full drawing package for your workplace interior design. We provide accurate floor plans and 3D visualisations, allowing you to explore your new office design before any office fit out and build work begins. Including all the finer details, including joinery pieces, tea points and mechanical and electrical plans – envisioning the entire project scope.


Office Interior Finishes

An excellent office interior design is all in the details. Together, we’ll select the fabrics, textures, furnishings and finishes for your final office design. From office furniture planning to detail and build, our team can help you.
