Reimagining a Cultural Landmark on the Isles of Scilly

Client: Council of the Isles of Scilly
Architect: Purcell Architects
Framework: Procure Partnerships

Project Background

Stepnell has been appointed as the principal contractor for the transformative refurbishment of the Grade II-listed Town Hall in Hugh Town, St Mary’s, on the Isles of Scilly. Working in partnership with the Council of the Isles of Scilly, Scilly Arts & Heritage, and the Isles of Scilly Museum Association, this ambitious scheme will breathe new life into one of the archipelago’s most significant heritage landmarks.

The scheme will see the Town Hall become home to a modern museum, cultural centre, 155-seat performance venue, new café overlooking Porthcressa Beach, and flexible community spaces for locals and visitors alike.

Scope of Works

Our role encompasses both sensitive restoration and significant new-build elements including:

  • Extensive internal demolition of a 1970s extension.
  • Gradual roof tile removal and replacement, including integration of photovoltaic panels.
  • Specialist conservation works, including removal of concrete pointing and repointing with breathable lime mortar.
  • Installation of a new lift shaft to improve accessibility.
  • Construction of new steel frames, groundworks, and timber cladding for the extension.
  • Installation of structural timber beams and columns to shape new internal spaces.
  • Careful logistical planning for materials delivery and storage to respect the island’s constraints and local community needs.

All activities are being conducted in close coordination with planning restrictions and heritage regulations, with a focus on minimising disruption to local residents and businesses.

“We are honoured to be a part of this transformative project that will not only restore a historic building but also create a vital space for the community. The Isles of Scilly hold a unique place in the UK’s cultural landscape, and we are committed to ensuring this project reflects the heritage and aspirations of its residents.” – Rob Speirs, Regional Director, Stepnell

Sustainability in Action: Step Energy’s Role

As part of our integrated approach to sustainability, Step Energy has designed and delivered a bespoke rooftop solar energy solution to power the future of the cultural centre.

Key Features of the PV System:

  • 32 kWp system delivering over 30,500 kWh/year
  • 156 m² of solar panels across multiple roof zones
  • 80 PV modules installed using a mix of in-roof and on-roof systems
  • CO₂ savings: Approx. 14,346 kg/year
  • Own power consumption: 54.1%, significantly reducing grid dependency

The system was engineered to blend seamlessly with the building’s conservation requirements while providing long-term energy efficiency for the facility. It supports the project’s commitment to environmental sustainability and complements the high-performance building fabric and M&E strategy.

Challenges and Solutions

Remote Island Logistics

With limited space and ferry access, we have developed a meticulous material delivery and storage strategy. All materials are stored off-site and transferred daily by forklift and trolley to reduce on-island congestion. Packaging is removed promptly to maintain site cleanliness.

Community Engagement and Business Continuity

Maintaining public access around the construction area and supporting neighbouring businesses has been key. We have established clear pedestrian routes, kept Silver Street shops accessible throughout the build, and contributed to public-facing communication materials including summer construction briefings.

Listed Building Sensitivity

As a Grade II-listed structure, conservation has been central. We are working with heritage experts to ensure all restoration – including mortar pointing and roof works – is carried out to the highest standards of authenticity and durability.

Craftsmanship and Heritage: Lawford Joinery

As part of our commitment to heritage excellence, our specialist joinery business Lawford Bespoke Joinery has been engaged to deliver bespoke timber features in keeping with the building’s historical character.

Key elements include:

  • Gothic Arched Sash Windows and Gothic Arched Casement Windows to the front elevation, faithfully replicating the original design.
  • Bespoke Servery Window within the new café extension, seamlessly blending traditional craftsmanship with modern usability.

Each unit is being carefully manufactured to conservation-grade standards using durable hardwoods and traditional joinery methods, preserving the building’s unique architectural identity while enhancing performance and longevity.

Social and Cultural Impact

The revitalised Town Hall will become a vibrant hub for arts, culture, and community life, supporting Scilly’s economy and enriching island identity. The project has received widespread support and funding from:

  • The National Lottery Heritage Fund
  • UK Government, MHCLG
  • UK Shared Prosperity Fund (via Cornwall Council)
  • Council of the Isles of Scilly
  • Cornwall Council
  • Arts Council England

Once complete, the facility will offer:

  • A museum celebrating Scilly’s maritime and social heritage
  • A year-round cultural venue for cinema, music, and theatre
  • Community meeting and event spaces
  • A café and Tourist Information Centre
  • Improved accessibility and sustainability features

“These plans will create a unique facility, museum and cultural centre, which will benefit residents and visitors alike for many years to come.” – Ann Tudor, Scilly Arts & Heritage

Looking Ahead

With enabling works now well underway, including scaffolding, demolition, roof upgrades and new construction. Stepnell remains committed to delivering a space that reflects the spirit, heritage, and future ambitions of the Isles of Scilly community.
