Full Service Interior Design

You don’t need more inspiration, you need a plan.

Renovating or building a home involves hundreds of decisions - and without a clear plan, it quickly becomes overwhelming.

At Assembly Interiors, we offer full service interior design across Melbourne and the Mornington Peninsula, guiding your project from early ideas through to a resolved, build-ready outcome.

Our approach translates your ideas into a home that feels considered, functional and sustainable – with clear, buildable designs removing guesswork and allowing your project to move forward with confidence.

We take care of the detail, so you don’t have to.


Depending on your project, this may include:

  • Spatial planning and layout refinement (Making your home work harder, flow better and feel right for the way you actually live.)

  • Kitchen, bathroom and joinery design (The hard working spaces, resolved properly.)

  • 3D visualisation, materials and finishes selection (So you can visualise the direction, understand the decisions and feel confident before anything gets built)

  • Detailed documentation for pricing and implementation (Clear drawings and schedules that give your builder what they need to bring the design to life)

Start Your Project

The goal is simple: a design that holds together from concept through to completion.

Clients work with me because I take the reins: clear process and communication, builder-ready documentation, decisive recommendations, and no “endless Pinterest spiral.” You value good design but don’t have the time to manage every detail. You want guidance you can trust and care about creating a home that feels like yours.

I’ll focus your thoughts, define your style and keep the project moving – without the overwhelm.

Our initial in-home consultation is $395, designed as the starting point to all successful renovation projects.

How the process works

  • Initial consultation

    We walk through your home, your plans and how you want to live.

    I want to understand your routines, priorities, pain points and plans for the future, as well as the opportunities and constraints of the property.

    Because good design starts with understanding the people who live there, not just the room dimensions.

  • Concept design

    This is where the ideas start to take shape.

    I develop the overall design direction, refining layouts, exploring joinery and establishing the look, feel and functionality of your home.

    You'll see the direction come together through 3D visualisation and initial material selections - giving you something tangible to respond to before we dive into the detail.

  • Design development

    This is where decisions are properly resolved. Materials, finishes, fixtures, cabinetry, lighting and all those seemingly small decisions that have a very large impact are properly resolved.

    Everything is considered together, so you don't end up with a collection of beautiful things that don't quite belong together.

  • Documentation

    A beautiful design is only useful if someone can actually build it.

    I prepare the drawings and schedules required to accurately price and confidently deliver the design.

    Less guesswork. Fewer surprises. A much smoother path from screen to site.
