A Considered Approach to Interior Design

INTERIOR DESIGN

A space is only a space,
until it feels like yours.

Tailored packages for residential and commercial spaces — from single-room designs to full-scale renovations.

OUR DIFFERENCE

Design with Confidence, not Confusion.

Refreshing your space can feel overwhelming - too many decisions, rising costs, uncertainty around what will work or not. More often, this leads to spending more than budgeted and feeling decision regret after only a few months.

 

But with the right direction, it becomes a more confident and enjoyable process, where each decision feels aligned and intentional. That's where we come in!

Gabriela Mastroianni
ABOUT US

Behind the Brand

Founded by Gabriela Mastroianni, an interiors and branding designer focused on practical, meaningful spaces.

Our studio was founded to bridge the gap between high-end design services and going it alone - where many are left navigating decisions without clear direction or support. 

We work with clients who want to improve their space without overcomplicating it, focusing on practical informed decisions that align with how you live, what you need, and how it adds value over time. 

Our approach is grounded in intention. We prioritise thoughtful, sustainable decisions: repurposing rather than replacing, timelessness over trends. 

 

We design with wellbeing in mind - shaping environments that support sense of calm, function with ease and connect people together.  

Working with residential and small commercial clients across Sydney, with consultation available Australia-wide and globally, we strive to bring clarity and direction to every stage of the design process.

Commercial

From layout to atmosphere, we design commercial spaces that make sense and feel reflect your brand story.

  • for compact, detail-rich spaces (under 80sqm). Small but strategic — perfect for boutiques, pop-ups, or offices where every element needs to pull weight.

  • for medium-scale venues (100–200sqm). Considered layouts and layered storytelling for showrooms, cafes, salons, or brand activations.

  • for large-scale, flagship, or destination spaces (200sqm+). Expansive, experience-led design with spatial branding at its core — ideal for venues with vision.

TESTIMONIALS + PRESS FEATURES

Gab understood our vision and guided us through a thoughtful process, helping us refine our style and turn it into a beautiful restaurant space. From concept to execution, she curated the perfect environment for our brand.

Bellevue Woolloomooloo

Sydney, Australia

Finding a style match to our vintage bathrooms felt nearly impossible. Thankfully, Gabriela brought the clarity we needed and delivered a cohesive design on time and in budget for our summer Airbnb launch. Guests constantly compliment the style - it became part of the experience.

Emily M.

Manly, Australia

We struggled to find heritage-appropriate pieces that honoured our estate's history without blowing the budget. Gabriela understood the brief, sourced the pieces and made the whole process effortless!
