Renovation & Residential Extension Architects
At Gregory Phillips Architects, we believe that transforming an existing house can be just as exciting—and often more rewarding—than starting from scratch. Whether you’re extending, reconfiguring, or renovating, we create homes that reflect your lifestyle, aspirations, and the potential of the building itself. Our services are designed to guide you through the process seamlessly, from concept to completion, with creativity, clarity, and care.
Why Choose Gregory Phillips for Your Renovation and Extension?
We specialise in the thoughtful transformation of existing homes—breathing new life into properties through contemporary extensions, interior reconfigurations, and sensitive renovations. With over three decades of experience, our award-winning practice has delivered exceptional results across a range of contexts—from period properties in conservation areas to modern urban dwellings and countryside retreats.
Working with an existing structure comes with unique challenges—from site constraints to planning sensitivities—but also offers unique opportunities. Our team brings a depth of knowledge and creativity to every project, ensuring that the old and new are integrated beautifully, both functionally and architecturally.
Whether you’re looking to add space for a growing family, improve natural light and flow, or reimagine your home for modern living, we have the expertise to deliver a result that feels entirely new—while respecting what already exists.
Our Process for Renovation and Extensions
Our process is specifically tailored to the complexities of working with existing buildings. We begin by understanding your objectives—whether spatial, aesthetic, or functional—and analysing the potential of your property. We consider site constraints, planning policies, and the architectural language of your home.
From there, we develop a concept that transforms your space—enhancing light, flow, proportion, and connection to the outdoors. We produce 3D visualisations, feasibility studies, and cost estimates early in the process to provide confidence and clarity.
We handle all aspects of the planning and statutory approvals process, including listed building consent where required. We coordinate necessary surveys and engage with trusted consultants to ensure a smooth path to approval.
Our technical detailed design phase prepares your project for construction, with detailed drawings and specifications. Whether you’re extending outwards, upwards, or reconfiguring internally, we design every element to a high level of precision and intent.
Throughout construction, we remain closely involved—monitoring quality, advising on finishes, and ensuring the design is faithfully delivered. We oversee the final stages, guide you through the handover, and provide ongoing support post-completion.

Sustainable and Thoughtful Design
As we move into a future of more responsible construction, our renovation and extension projects are designed with sustainability at their core. Reusing and upgrading existing structures is one of the most sustainable ways to improve a home—and we enhance this further through energy-efficient technologies, low-carbon materials, and high-performance detailing.
From upgraded insulation and glazing to the integration of renewable energy systems and smart home technologies, we ensure your transformed home is not only beautiful, but future ready. Our approach balances environmental performance with comfort, style, and longevity.
