OUR PHILOSOPHY
Architecture and interior design for spaces that are made to last.
Phasezero Design Studio is a London-based architecture and interior design practice specialising in luxury residential projects, sensitive historic building restoration, and bespoke hospitality interiors. We work across the UK, Italy, and Spain, from concept and planning through to construction delivery and final fit-out.
Our approach starts before the drawings begin. We call it Phase Zero: the strategic, pre-design thinking that makes every subsequent decision more purposeful. It is why our projects finish on time, on brief, and, in the words of the clients who commission them, feel entirely right.

WHAT WE DO
Our Services
Architectural Design
Bespoke architectural design for luxury residential projects, historic building extensions, and hospitality developments across London, the UK, Italy, and Spain.
Interior Design
We design for high-end private residences, historic homes, and boutique hospitality environments. Our interiors begin with the architecture of a room — its proportions, light, and material character. Everything else follows from there.
Landscape Design
Landscape and garden design as an extension of the architecture — external spaces that respond to the building and the site rather than sitting alongside them.
Management
Full project management from planning application to final handover, coordinating architects, engineers, contractors, and specialist trades so you are not managing a complex construction process yourself.
OUR APPROACH
Design Philosophy
Biophilic Design
Integrating nature into every space, creating environments that nurture wellbeing and connection to the natural world.
Sustainability
Responsible design that respects the planet. We source ethically, build efficiently, and design for longevity.
Attention to Detail
Every material, joint, and finish is considered with precision — because excellence lives in the details.
Timeless Aesthetics
We design beyond trends. Our spaces age gracefully, growing more beautiful with time and use.

CLIENT STORIES
What Our Clients Say
What stood out most was their attention to detail at the earliest stages. Lisa helped us define our priorities and align all stakeholders before moving forward, which made a huge difference as the project progressed. Her input has had a lasting impact on how we approach new developments. Highly recommended for anyone looking to get things right from the outset.
Residential, Grade II listed building
Working with Lisa & Flavia gave us confidence from day one. They quickly understood the complexities of our project and translated them into a clear, structured approach. Communication was always straightforward, and they were proactive in highlighting risks we hadn’t even considered. It’s rare to find a team that combines strategic thinking with such practical insight.
Hospitality Client, Management
We approached Phasezero at a very early stage with just a rough idea, and they helped turn it into something tangible. Their ability to challenge assumptions while still respecting our vision was incredibly valuable. The clarity they brought to the brief saved us both time and cost later on. It felt like a genuine partnership rather than a standard consultancy service
