Design-led, sustainability-driven, people-focused

At Lumin Architects, we believe exceptional architecture should enrich everyday life—enhancing well-being, honouring the environment, and elevating the way you live. Founded in 2018 by Lucy, an ARB-registered architect with over a decade of experience across both luxury residential and large-scale developments, Lumin was born out of a desire to offer more than just beautiful design. Our mission is to create thoughtful, sustainable homes for families who value quality, craftsmanship, and a personalised journey.

In 2025, Lucy was honoured with the Women Leaders UK Award in the Manufacturing & Construction category — a recognition of her values-led approach to architecture and the thoughtful way she’s grown Lumin Architects while navigating early motherhood.

We work with a select number of clients each year to ensure our full attention and creativity is focused where it matters most—on delivering designs that are as meaningful as they are timeless. Whether you’re transforming your forever home or investing in a high-spec development, we offer a tailored experience rooted in trust, collaboration, and integrity.

Our Design Philosophy

Lumin Architects was founded to bring together exceptional design, environmental responsibility and a deeply considered client experience. We work with homeowners who want a calm, functional and uplifting place to live — and with small developers who want high-performing, well-designed homes that sell with confidence.

Our approach balances:

  • Light, simplicity and timeless design

  • Sustainable principles embedded from the outset

  • Clear communication and structured workflows

  • Technical coordination that reduces risk during construction

  • Commercial awareness for developer-led projects

We believe great architecture enhances wellbeing, strengthens communities and stands the test of time.

Our Unique Approach:
Innovating for Your Well-being

At Lumin Architects, we design beyond the visual—we create spaces that feel as good as they look. Inspired by the WELL Building Standard, we thoughtfully shape each environment with natural light, clean air, acoustic comfort, and healthy materials. Every detail is intentional, contributing to a home that supports your health, mood, and energy.

Our projects are grounded in sustainability—from reclaimed and responsibly sourced materials to energy-efficient technologies that tread lightly on the planet. And because your time is valuable, we manage each stage from concept to completion with clarity and care, ensuring a smooth, transparent journey.

If you’re seeking a design partner who shares your vision for a sustainable, design-led, high-quality home—and you're ready to invest in that ambition—we’d love to hear from you. We take on a limited number of projects per year to maintain the integrity of our work and client relationships.
