HISTORIC HOUSES & ESTATES / INTRODUCTION

We are trusted custodians of heritage and creative partners for today.

Purcell is an international practice of Architects, Masterplanners, and Heritage Consultants. Since 1947, we have been leading exemplary projects to protect, enhance and evolve the world’s most significant historic places and listed buildings. Our specialist teams have extensive knowledge and experience of maximising opportunities to renew and redevelop heritage assets of all scales and complexities, from internationally important World Heritage Sites and Grade I-listed historic houses to country houses and rural estates in private ownership.

Whether our clients wish to refurbish their country house to meet contemporary lifestyle requirements, extend existing buildings, or obtain consent for significant new buildings, we are highly experienced in negotiating with local planning authorities, Historic England and other heritage organisations, to secure planning permission and listed building consent for proposed changes.

We are passionate about design quality at all scales, whether developing a masterplan for a rural estate or remodelling a country house or farm buildings to suit family needs, we strive to create beautiful homes that celebrate great design, craftsmanship, and detail while being practical for everyday life.

Owing to the confidential nature of our work for private clients, we include only a few examples of our work in this brochure. We can present a wider selection of our most ambitious transformational designs at a private consultation.

HISTORIC HOUSES & ESTATES / CONSERVATION EXCELLENCE

Inspired by a deep understanding of context, we craft the identity of the unique places in which we work by cherishing their heritage.

Understanding place forms the foundation of everything we do. By understanding why a place is important, our specialists enable clients to unlock the potential of their heritage sites. Reshaping and reusing our built heritage is vital to creating a more sustainable future and contributing to healthy, beautiful places.

We work with a broad range of clients, from homeowners and estates to local authorities and custodians of cultural and historic sites. We help them better understand their properties and undertake sensitive change to achieve successful and sustainable places. We work closely with Historic England and planning and conservation officers to gain complex statutory consents for work to listed buildings and historic places in the most sensitive contexts including Scheduled Monuments, UNESCO World Heritage Sites and National Parks and Historic Parks and Gardens.

Our in-depth knowledge of and enthusiasm for the built environment enable us to set out the potential and value of heritage sites whilst conserving and enhancing their significance. This understanding allows us to provide expert and bespoke advice that inspires creativity and enables the best of the past to be retained, made useable in the present and continue into the future.

We pioneer a conservation-led approach that celebrates our past and responsibly considers the legacy we will leave for future generations.

Oxburgh Hall Norfolk, UK

Raising the roof to secure the future Purcell was architect and lead designer for the ambitious Raise the Roof project at Oxburgh Hall – the largest conservation effort in the building’s history.

The £6m conservation programme across the Grade I listed building saw critical repairs carried out to the 15th century hall’s roof, chimneys, windows and medieval gatehouse facade, all while remaining open to the public.

Alongside our work for the National Trust, we have also acted for the Bedingfeld family on a range of conservation and improvement projects within their private residential accommodation at Oxburgh Hall.

The restoration completed in 2023, securing the future of this iconic National Trust property for generations to come. In 2024, our Heritage Consultancy team prepared a new Conservation Management Plan and gazetteer, strengthening the long-term stewardship of the gardens and wider historic landscape.

Shaping a historic home for today’s school and tomorrow’s visitors One of the finest 18th century classical buildings in Europe, Purcell has been leading a phased multi-million pound Strategic Restoration programme at Grade I listed Stowe House, Buckinghamshire for over 25 years.

Since leading the site masterplan, we have delivered successive phases that restore and modernise key spaces - including the library, music rooms, dining hall, as well as major external fabric repairs - ensuring the house can effectively function as a school and visitor destination.

Our exemplary conservation and maintenance work to the stonework façades and historic lead roofs has won numerous international awards, safeguarding the future of this classical masterpiece and enabling its removal from the Historic England Heritage At Risk register.

The Auckland Project Bishop Auckland, County Durham, UK

Art, faith, and heritage safeguarded through restoration Purcell, in collaboration with Níall McLaughlin Architects, was appointed as architect and design team lead for the transformation of Auckland Castle, a 900-year-old, Grade I listed episcopal palace in County Durham. The project forms the centrepiece of The Auckland Project’s long-term vision to drive social, economic and cultural regeneration in Bishop Auckland.

The private residence of the powerful bishops of Durham for nearly a millennium, Auckland Castle had become disconnected from the community. The Auckland Project sought to reverse this legacy by opening the castle and its extraordinary collection to the public, creating a space for faith and heritage that would engage both locals and visitors.

Auckland Castle has an exceptionally high heritage significance. As a result, the development required a meticulous process of statutory consultation and consents.

Purcell led the project through a detailed appraisal of the development’s heritage assets to understand their significance and capacity for change.

Where once this was a palace just for the Prince Bishops, now everyone can come to explore the magnificent rooms, wander through the gardens, admire art or attend an event.

HISTORIC HOUSES & ESTATES / TRANSFORMATION & REUSE

Knole Estate Kent, UK

Conservation of a former royal palace Originally an archbishop’s palace, then a royal residence, Knole has been home to the Sackville family for over 400 years. In 1946, the estate was gifted to the National Trust and opened to the public, while the Sackville-West family retained the private apartments and much of the surrounding parkland.

Purcell has been the commissioned architect for all work at Knole since 1993, delivering a continuous programme of repair and conservation works for the National Trust across the public areas of the estate, while also acting separately for the Sackville-West family on works to their private residential accommodation.

Various parts of the house have been re-roofed and major repair projects have been undertaken in the Orangery and Long Gallery. The house has been largely re-wired, with conservation heating added to display rooms. Comprehensive fire detection, alarm and lightning conductor systems have also been installed, as well as a major programme of work to reorder and repair the family’s private apartments.

HISTORIC HOUSES & ESTATES / TRANSFORMATION & REUSE

By championing innovation rooted in heritage, Purcell helps historic houses and estates thrive for generations.

As one of few practices dedicated both to the care and development of historic places and the creation of innovative new buildings in sensitive contexts, we understand that heritage assets must adapt and change to meet contemporary lifestyles and to remain sustainable. Purcell helps historic houses adapt with integrity, ensuring they remain viable and meaningful in the present as well as the future.

Our in-house specialists in architecture, heritage consultancy, surveying, sustainability, masterplanning and regulatory compliance work as one team, allowing us to understand each site’s unique history, condition, performance and potential. All of our projects start with gaining a deep understanding of the place and context alongside understanding our clients’ preferences, needs and aspirations for their home or historic building.

Confident and experienced with both traditional and contemporary design solutions, our proposals are always bespoke, unique and tailored.

We see ourselves as creative stewards, balancing continuity with evolution. Working holistically helps our clients navigate statutory processes, develop long-term strategies, future-proof their buildings, manage risk and make targeted, informed decisions. Whether safeguarding a treasure house, revitalising a private home or planning long-term estate evolution, our approach supports care today and strengthens legacy for tomorrow.

Boston Manor House London, UK

Resurrecting a Jacobean gem Boston Manor is an extraordinary Grade I listed Jacobean house in the London Borough of Hounslow, rescued through a £5.7m National Lottery Heritage Fund and Historic England funded project led by Purcell as architects and lead consultants. Following extensive community consultation through early stages to define a spatial brief, our project delivered extensive conservation repairs to remove the house from the Heritage at Risk Register, and fully restored historic interiors to exemplary standards.

Our designs carefully integrated a passenger lift into a former privy shaft within the house with a rooftop extension, designed a new visitor café, and created exhibition galleries to provide a sustainable and fully inclusive community cultural resource for the London Borough of Hounslow - one of the most culturally and economically diverse boroughs in London. Our designs transformed the Victorian service wing into lettable office and education accommodation for creative industry business start-ups, bringing a longterm sustainable income and new audiences to this unique historic place.

Burghley House Lincolnshire, UK

A holistic masterplan for an engaging and connected visitor experience Burghley House is a masterpiece of Elizabethan architecture — a grand 16th century English country house which stands tall in Stamford, Lincolnshire. Built and designed by William Cecil, Lord High Treasurer to Queen Elizabeth I, the house is still lived in by the Cecil family. Purcell was commissioned to design a masterplan for site, with a focus on improving the visitor experience of the house, grounds and garden, as well as to lead the conservation and restoration of the Lion Bridge, to ensure its preservation for the next 100+ years.

The purpose of our masterplan is to take the long-term view on how to improve the visitor experience of Burghley, including transforming underutilised buildings and planning a careful and considered route throughout the estate to better manage visitor flow.

A carefully considered balance between conservation and change Set within 250 acres of public parkland and woodland, Purcell has developed a comprehensive masterplan for the Haigh Hall estate. Proposals are centred on conserving its historic character while enhancing its role as a vibrant and accessible community destination.

The approved proposals, supported by a £20m Levelling Up Fund grant, place heritage and community use at their core, reimagining the 18th century hall as a multi-functional space for a wide range of visitors.

Alongside these new uses, the scheme includes essential conservation and repair works to address long-standing maintenance issues and to secure the building’s future.

The Future of Historic Houses

37

HISTORIC HOUSES & ESTATES / THE FUTURE OF HISTORIC HOUSES

Adapting old buildings for new uses, extending, modernising and making them accessible and socially relevant has a new urgency as we face up to the impacts of climate change.

Our approach has always been one of creative custodianship - learning from the rich history of the buildings we work with and innovatively imagining ways to ensure their long-term enjoyment, accessibility and functionality for future generations.

Heritage buildings are one of our most powerful assets in the constant struggle against climate change and biodiversity loss. By preserving and prolonging the life of our existing buildings, we are protecting our natural resources by making use of what we have.

We strongly believe heritage buildings should not be seen as a barrier to a sustainable and equitable future.

In recognition of this, we have been at the forefront of delivering pioneering research and guidance for energy efficiency retrofits in heritage buildings. We co-authored the Historic England Handbook on Energy Efficiency Measures in Traditional and Historic Buildings, and our collaborative work with the City of London Corporation has culminated in an open-source Heritage Building Retrofit Toolkit, launched in March 2024. Working with many clients facing the challenges of decarbonising their complex estates, we take a whole building approach, one which ensures heritage values are balanced against the urgent need for climate adaptation.

Ledston Hall Leeds, UK

Conservation and sustainable innovation to rescue a stately home Purcell developed an initial strategic plan and subsequently delivered a phased programme of conservation, which included extensive fabric repairs, sensitive extensions, and interior adaptations to create luxury residential homes and private function spaces, all while preserving historic features.

The restoration and conservation repairs, which led to the removal of both the Grade I listed hall and the Grade II* listed gate piers from Historic England’s Heritage at Risk register, have secured a sustainable future for Ledston Hall.

The design adopted a conservation-led approach, underpinned by an innovative sustainability strategy. Notably, Ledston Hall became the first Grade I listed building in the UK to receive Listed building consent for the replacement of its historic windows. This landmark approval demonstrates that progressive energy-saving measures can be successfully integrated with the conservation of heritage assets.

“Purcell is among the best heritage architects in the industry. We’ve had the pleasure of working with them over the past four years on a complex Grade II-listed site in Hampshire, including a registered park and garden. Their creative design work and deep historical insight were pivotal in securing planning permission, balancing landscape response with heritage sensitivity.

Throughout delivery, they’ve collaborated seamlessly and harmoniously with a world class consultant team—unafraid to challenge where needed. For any future project of historical significance and complexity, we would involve Purcell without hesitation. They’re a credit to the profession and a genuine pleasure to work with.”
