Our Approach to Creating Spaces that Inspire

A designer’s role is broader than most people realise. When a designer manages a project, they ensure that every part of the process (and more) is handled to ensure that your significant investment of money, time and effort is safe and secure.  

The right designer will manage both the experts AND the process. 

We’ll guide you through every step of the process using our proven values-based methodology and bring a level of aesthetic expertise to your fit out that most people don’t have. We’ll help you choose colours, textures, and finishes that will create a cohesive look for your project. This can be especially important if you’re not sure how to begin or if you have very specific ideas about what you want.

Our Process

No two spaces are the same – that’s why we take the time to get to know you and your business. We want to make sure that we design a space that looks great and helps you achieve your goals.

The Project Scoping and Analysis occurs after our initial consult and is the first step in our journey together.

At this stage, we collect as much information as possible. This is where we gain an understanding of your goals, timeline, and budget; we also eliminate assumptions, conduct a feasibility study, identify project constraints, and find your best options. We’ll also visit the site to make sure we have a grounded understanding of the space.

We then send you a custom proposal including a project summary, recommendations, and outline the key deliverables for your project.

If you’re not sure where to begin: Download our Project Planning Guide which can help you get started.

We start by researching and preparing concept imagery and initial drawings to help us get on the same page as far as what kind or style is desired before moving forward together into putting together your ideal build team.

We also conduct further research and analysis, ensuring compliance with building and safety regulations, local planning regulations and restrictions. There may be laws surrounding the preservation of the local environment or any historic parts of a building and we need to take into consideration.

At the conclusion of this phase, we present you with a detailed design concept, which fulfills all your brief’s requirements. 

This is where the fun begins. We work closely together to translate your vision into a package of drawings and documents detailing the elements that make up the internal and external environments of your build.

This is used to guide cost planning and estimates for our scope of work.  We are 100% transparent about our process and will keep you in the loop every step of the way.  We’ll liaise with contractors and other tradespeople to get the best deals on materials and labour, with the goal of keeping within budget without sacrificing style or quality.

The outcome of this phase will allow a seamless transition into Construction Documentation.

Construction documentation refers to the drawings, plans and other information that is used to describe a construction project. This can include everything from the overall layout of the project, to detailed drawings of individual elements. 

This documentation must be accurate and complete to avoid problems during construction.

Our extensive experience in design and construction ensures that every project is managed and completed with care. 

We work closely on project delivery with our clients from start to finish, managing the entire project and working with builders and services consultants to ensure that the project is completed on time and within budget.

At every stage of your project, we apply our experience and expertise to reduce risk, manage the budget and improve the functional design of your project. 

We have years of experience in designing commercial spaces and we know we can create something amazing for you.

Frequently Asked Questions

There is no right or wrong answer to this question – it ultimately depends on your preferences and needs – and if you already have those services lined up. We have built great working relationships with a range of service providers – builders, services consultants, engineers etc – and we know they offer excellent advice and guidance. We would only recommend trusted service providers that match your goals and project style.

When hiring an interior designer, the first step is usually an initial consultation. This meeting helps us determine if we’re a good fit for each other and if our design styles are compatible. If you’re happy with what we offer, we sign up and get to work. You can book a consultation with us if you’re ready to get started.
