Núria Casellas

Interior Stylist & Spatial Designer

From Barcelona. With an engineering foundation and extensive hands-on experience, I craft interiors where light, material, and proportion define the space. My work merges Scandinavian clarity with Mediterranean warmth, creating timeless, refined environments that balance function, atmosphere, and quiet luxury.

01
Timeless Simplicity

I design spaces that feel calm, intentional, and enduring, free from trends, excess, or visual noise. Every element has a purpose, and nothing is accidental.

02
Natural Harmony

Materials, light, and textures are chosen to create balance and wellbeing. Inspired by Scandinavian clarity and Mediterranean ease, my interiors connect people to nature and to a slower, better way of living.

03
Quiet Luxury

Luxury is not about showing off, but about quality, craftsmanship, and how a space makes you feel. I focus on refined details, comfort, and elegance that speak softly but confidently.

My
brand vision

To create spaces where light, design, and refined sophistication converge, reflecting the harmony of Scandinavian minimalism and the warmth of Mediterranean style.

At LJUS Studio, I transform interiors and outdoor spaces into immersive spaces. Every project is guided by a balance of light, thoughtful design, and refined sophistication, blending the clean, minimalist elegance of Scandinavia with the warmth and vitality of Mediterranean style.

With 17 years of experience in project management, interior styling, and lighting design, I bring a personal, hands-on approach to every detail, ensuring each space feels both harmonious and uniquely yours.

Design without limits

  • My work is not about fixed packages or predefined solutions, it’s about listening, sensing, and creating spaces that reflect you.

    I work across interiors and exteriors, blending Scandinavian clarity with Mediterranean warmth, always adapting the process to your needs, your space, and your vision.

  • For clients who need clarity, mood, and a strong starting point.

    Includes for example:

    • Visual inspiration & mood direction

    • Color palette & material suggestions

    • Spatial feeling & atmosphere guidance

    • Initial ideas for interior and/or exterior

    Ideal if you want to define the soul of your space before going deeper.

    A Flexible, Thoughtful Process

    No two projects are the same.
    Some clients need clear guidance. Others want full execution. Many fall somewhere in between.

    I adapt my involvement to your needs, from concept and design to coordination and follow-up, ensuring the process feels smooth, structured, and easy for you.

    You don’t need to have everything figured out.
    That’s part of my job.

  • I collaborate with clients who value atmosphere, intention, and functionality, and who want spaces that feel right, not just look good.

    My role often goes beyond styling. I guide, design, coordinate, and adapt, always shaping spaces that support people, purpose, and everyday life.

  • I work closely with real estate professionals to help properties reach their full potential, emotionally and visually.

    This can include:

    • Styling guidance to increase appeal and perceived value

    • Redecorating spaces using my own curated furniture and décor

    • Temporary furnishing and styling for sales or rentals

    • Preparing spaces specifically for photography and marketing

    • Photography

    • Creating a clear visual story that helps buyers imagine themselves living there

    Whether you need strategic advice or a full transformation, the goal is always the same:


    to make the space desirable, inviting, and easy to sell.

  • For hotels, restaurants, cafés, and hospitality projects, I design spaces that are welcoming, durable, and adaptable, without losing warmth or character.

    I often:

    • Style open and shared areas (interior and exterior)

    • Design concepts that work year-round, with seasonal flexibility

    • Select furniture and décor that can shift between summer and winter

    • Collaborate with maintenance and operational teams

    • Follow the project through implementation to ensure coherence

    Projects can follow one of my design frameworks or be fully tailored, depending on the scale, timeline, and operational needs.

  • I support companies that want to improve their social and shared environments, spaces where people connect, focus, and recharge.

    This includes:

    • Redesigning social areas, lounges, and common spaces

    • Creating environments that encourage interaction, creativity, and well-being

    • Designing areas for both focused work and relaxed moments

    • Supporting Nordic work culture values such as fika, openness, and balance

    The result is a space that strengthens company culture and makes people feel good being there.

  • I work with educational spaces where safety, learning, and emotional well-being are essential.

    My approach focuses on:

    • Safe and functional decoration

    • Environments that support learning and development

    • Creating calm, happy, and stimulating spaces

    • Designing indoor and outdoor areas with purpose

    • Organising zones that encourage different senses, activities, and age needs

    From kindergartens to public institutions, the goal is always to create spaces where people, especially children, feel secure, inspired, and cared for.
