About CZARNIECKI ECO DESIGN - Interior Design and Residential Architecture Studio in London
STUDIO DIRECTION
About the Studio
Founded and led by an experienced interior designer in London with over 23 years of residential practice.
Now fully focused on London and the UK, the studio delivers projects ranging from considered room transformations to complete architectural schemes.
Each project is shaped by technical precision, a calm process and results designed to endure.
Good architecture is not about impressing. It is about making your life measurably better, every single day. At CZARNIECKI ECO DESIGN, we bring that standard to every project we accept in London and across the UK.
A London residential studio with over 23 years of international expertise, built on architectural precision, material intelligence and a deep understanding of how people live.
Our Approach
London homeowners face a specific challenge: high expectations, complex planning environments and contractors who expect fully resolved drawings before they quote. We understand this because we have been working within the London residential market since 2010.
Our role is to take complete technical and design responsibility for your project, from the first spatial concept through to build-ready documentation.
We provide photorealistic 3D visualisations so you see exactly what your home will become before a single wall is touched.
Every material is specified. Every junction is detailed. Every decision is made with long-term comfort and value in mind.
Whether you are planning a carefully considered interior transformation that improves how your home functions,
a bespoke kitchen, fitted storage or joinery system built to precise architectural standards,
or a full home renovation, rear extension or new-build residential project in London or the Home Counties,
we bring the same level of rigour to every scale.
Our clients are not buying a drawing service. They are buying clarity, confidence and the assurance that the result will be exactly what was agreed.
You can see how this works in practice on our process page.
The Practice
The studio was founded in London in 2010 by Łukasz Czarniecki, drawing on a professional background that began in precision joinery and craft before expanding into full residential architecture and interior design. Established as a limited company in 2023 under the name CZARNIECKI ECO DESIGN, the practice has consistently delivered projects where technical discipline and spatial sensitivity work together without compromise.
We work with homeowners who value quality over speed, who want to understand every decision before it is made, and who expect the finished space to reflect their life, not a generic template. Over more than two decades, we have built a reputation for calm, professional process and spaces that endure.
Borderless Studio, London Standards
Our core work is based in London and the UK, with additional projects delivered in Poland. Every project is coordinated through a fully cloud-based workflow, with 3D documentation, material schedules and technical drawings shared clearly at every stage. Wherever you are in the UK, you receive the same standards, the same access and the same professional accountability.

Łukasz Czarniecki
Founder & Studio Director
For over 21 years I have lived in London, while continuing to work regularly from my hometown of Szczecin for clients in Poland. This dual perspective allows me to deliver projects with technical confidence and a calm, measured approach.
My work combines architectural precision with the realities of everyday family life. From single-room transformations to complete interior schemes, I focus on detail and long-term comfort at every stage.
I understand how the construction market operates in Poland. That is why every project includes clear technical documentation designed to protect the client throughout the build process. -
Gabriela Sokołowska
Architect
Gabriela brings 25 years of professional experience, translating complex design ideas into practical, durable interiors. She leads projects in Poland from initial concept through to full construction documentation, ensuring precision and everyday usability.
For the client, this means confidence that the vision will be realised without compromise. At every stage of the process, there is support from someone who understands both the design itself and the practical realities of construction.
2006
FOUNDATIONS OF CRAFTSMANSHIP
The journey began in Szczecin, Poland, rooted in the discipline of precision joinery. This period built our deep respect for materials and the technical mastery required to turn a design into a perfectly crafted reality.
2010
LONDON ESTABLISHMENT
Łukasz Czarniecki established the independent practice in London. British design sensibility met European technical precision, creating a distinct approach to residential interior design and architecture focused on high-quality, stress-free living.
2023
THE ECO-LED EVOLUTION
The studio evolved into CZARNIECKI ECO DESIGN, shifting focus toward sustainable, healthy architecture that actively improves daily comfort and long-term well-being. The same technical rigour, now guided by environmental responsibility.
If you are planning a project in London or anywhere in the UK and you want it done with real precision and genuine care, we would be glad to hear about it.
