About Us

I+D Studio is a full service, boutique interior design studio located on Sydney’s lower north shore. Originally established 20 years ago as the design arm of McNally Architects, I+D Studio was incorporated as an independent business in 2018. 

Our design philosophy for any space we create, is that it should evoke feelings of safety, comfort, warmth, engagement and motivation. We believe that great design must enrich the lives of those who live there and help to create harmonious and productive communities. 

We are experienced in concept development, interior design and decoration, documentation, project management and procurement. We take pride in our open and collaborative engagement with our clients. Our depth of knowledge in all facets of the design process means that we are agile in adapting to client changes and budget challenges.

Our Services

As a smaller studio, we take pride in our personalised approach and involvement in every project. I+D is unique in having a carefully curated team that is highly skilled in multiple disciplines. This gives our clients access to resources typically offered by large firms without the associated high overheads and allows us to offer a cost-effective solution for projects with potentially changing requirements.

Our Approach

No matter the size of the project, our design approach is divided into four stages:

Stage One | Concept Development

We listen to our client’s objectives to clarify and define the basis for the project. We then develop a scope of works ensuring that the integrity of the design vision is captured. We recognise the need for client collaboration and possible changes throughout the project and adapt accordingly.

We then create the conceptual documentation. This communicates our inspiration and creative adaptation of all design elements. Every design decision is run through this filter including custom joinery, furniture, lighting design, soft furnishings, artwork curation and decorative items.

Stage Two | Design Development

Following concept approval, we refine and confirm all finishes and design detailing.
The furnishing fittings and equipment (FF&E) schedule is finalised which outlines and specifies all finishes and furniture, lights, window treatments and signage to facilitate tender and construction. The documentation package includes floor plans, wall finishes plans, ceiling plans, elevations and joinery details. The furnishing schedule is created and incorporates selected soft furnishings, artworks and styling with detailed layout plans, sample finishes boards and furnishing swatch books produced.

Stage Three | Construction

This is where design starts to become reality. We liaise with appointed project consultants – architects, engineers, landscape architects, audio specialists – and integrate their documentation with ours. We attend site visits during construction to assure correct installation of all interior finishes.

Stage Four | Furnishing & Post Occupancy Evaluation

When the construction is complete, we then focus on procurement, delivery and installation of furnishings, installation of window furnishings and artwork placement and decorative styling of individual rooms. We also conduct a post occupancy evaluation to ensure quality control and absolute client satisfaction.


At I+D we think about styling as an important layer in the design process.  Styling adds personality and completes the design in any space. Complimenting the right soft furnishings, lighting and artwork can transform, refresh and provide a unique esthetic to relax, invigorate and motivate your surroundings.

I+D Styling experience spans across residential, commercial, schools and aged care. Our styling provides a range of services from consultation and layout reommendations through to complete specifications and fitout management. We have expertise in colour consulting, fabric design and furniture manufacture which allows for custom designs through our network of incredible suppliers.

Whether it be a child’s bedroom that needs a new fresh look or an office space that requires updating, our team has the experience to transform any space for any budget.
