Reviving heritage through craft and care: The transformation of York House, Penzance

Bailey Partnership is proud to share the story of our regeneration and conservation project at York House, Penzance – a development recently shortlisted for the 2025 CESW Awards. This ambitious and rewarding project represents the best of collaborative, heritage-led design and construction, breathing new life into a historic Grade II listed property while preserving its legacy for generations to come.

A building with a story
Built in 1825 as a rural home for John Pope, York House has long stood as a landmark of late Georgian architecture in Cornwall. Over the years, it has adapted to various community needs – first as the West Cornwall School for Girls in 1929, then as council offices from 1974. By the time the site was acquired for redevelopment as part of the wider St. Clare housing scheme, the building had been unoccupied for some time and following fire and theft quickly fell in to significant disrepair.

A centrepiece of community-led development
From the outset, the vision for York House was clear: to place this iconic structure at the heart of a modern, high-quality residential development. The building would inspire the palette and character of its surroundings while being restored into 11 elegant one and two-bedroom apartments that respected its original form.

The aim was not simply preservation, but rejuvenation – maintaining the grandeur of Georgian proportions and detailing while delivering the comfort and performance expected by 21st-century residents. Key original features, such as sash windows, granite façades, and ornate joinery, were retained and sympathetically restored by local artisans and craftspeople.

Overcoming unforeseen challenges
In 2018, disaster struck when a fire destroyed a significant portion of the rear structure. This was followed by the theft of lead roofing, compounding the building’s vulnerability to water ingress. These events triggered major redesigns, structural stabilisation, and years of moisture management before work could continue. Despite these setbacks, our commitment never wavered.

Crafting solutions required the close collaboration of our architects, surveyors, conservation experts, and the client, Vistry Cornwall South West. Navigating the evolving requirements of the warranty provider, Building Control, and Conservation Officers involved numerous Listed Building Consent applications and careful consideration of every detail.

Craftsmanship at its finest
Traditional techniques were employed throughout the restoration:

• Stonework and lime mortar repairs by skilled masons
• Sash window restoration by artisan joiners
• Handcrafted plaster cornices and curved skirting recreated using steam bending
• Scantle roofing laid in diminishing courses in tribute to local vernacular practice

Modern updates were introduced where appropriate, including discreet secondary glazing, energy-efficient boilers, and insulated linings – all balanced against heritage constraints. WUFI software was used to assess moisture risk and tailor designs to avoid interstitial condensation.

Preserving legacy, enhancing performance
Despite the building’s age and challenges, all completed apartments achieved at least EPC C ratings – a strong outcome given the heritage constraints. Acoustic insulation and fire compartmentalisation have also been upgraded to exceed modern standards, ensuring both comfort and safety.

This achievement would not have been possible without the enduring efforts of a dedicated project team – some of whom have remained involved since the start of the scheme in 2017. Their continuity and knowledge transfer were instrumental to the project’s success.

An award-worthy effort

Today, York House stands not only as a beautifully restored piece of Cornish heritage but as a thriving residential asset that contributes to the local community. The project has been recognised on Historic England’s National Heritage List, and our internal CPD programme has captured its lessons to inform future conservation work across the practice.

The York House project exemplifies our multidisciplinary expertise, heritage sensitivity, and determination to rescue and repurpose important buildings. We’re proud to have worked alongside Vistry Cornwall South West and SMT Associates in delivering a project that balances tradition, technical rigour, and community value.

As we await the CESW Awards results, we’re thrilled to see this incredible journey and team effort in the spotlight.
